In later life, weight loss can be a double‑edged sword. A few pounds off the joints can be both helpful and risky. Shedding a few pounds may ease joint pain, but losing weight without meaning to can be a warning sign. Fast weight loss can also lead to muscle loss, which is key to staying independent.

Experts also point out practical issues: injections need good vision, steady hands, and a regular routine. Stomach and bowel side effects can be tougher for seniors, especially if they’re already losing weight without trying. complicate life for older adults — and how to approach them with a “safety first” mindset.

1) Aging changes the risk–benefit math (even when a drug “works”)

Older adults, especially those who are frail or have several health issues, are often left out of clinical trials. This is important because average trial results may not match the real-life experience of a 75-year-old who takes several medications and needs to manage appetite and hydration.

A 2024 debate paper on GLP-1 drugs in older patients, including those with kidney disease, points out that limited trial data and multiple medications make it harder to judge safety and effectiveness for frailer seniors. Clinicians need to make decisions based on each person, not just on averages. In simple terms, the real question is not whether GLP-1s are good or bad, but whether they help this specific older person with their unique health needs.

There’s another subtle issue: in later life, the goal is often less about chasing an ideal weight and more about protecting function—walking safely, rising from a chair, maintaining balance, staying hydrated, and maintaining enough strength to live independently. So for older adults, the most important question isn’t “How much weight will I lose?” It’s “What will this do to my strength, my nutrition, and my ability to stay steady on my feet?”

2) Common side effects can become serious for older adults.

GLP-1s often cause nausea, vomiting, diarrhea, constipation, and less appetite. Younger people may find these symptoms unpleasant but manageable. For older adults, though, these issues can quickly lead to dehydration, dizziness, and falls, especially if they also take blood pressure medicines or diuretics.

Current FDA labeling for semaglutide products highlights this pathway: stomach and bowel side effects can lead to volume depletion, and acute kidney injury has occurred, including in postmarketing reports. The label advises monitoring kidney function when starting or increasing doses in people who develop severe gastrointestinal reactions, and it notes that dehydration has been part of reported kidney injury cases.

This is how many real-life problems start: a few days of not being able to eat or drink much, then feeling lightheaded, falling, or needing emergency care for dehydration. Older adults may not feel as thirsty and may have less ability to recover. So, it’s important to watch hydration, electrolytes, blood pressure, and kidney function, especially in the first months of treatment and after increasing the dose.

3) Muscle and frailty: losing weight does not always mean better health.

The headline benefits of GLP‑1s often focus on pounds lost. But the body doesn’t lose only fat. Lean mass (including muscle) can drop, too. This matters in older adults because age‑related muscle loss (sarcopenia) is already common — and it’s tightly linked to frailty, falls, and loss of independence.

A 2025 mini-review on older adults warns that starting and stopping GLP-1s repeatedly can change body composition, sometimes leading to ‘sarcopenic obesity’ — having too much fat and too little muscle. The authors are not saying to avoid GLP-1s, but to remember that weight loss does not always mean better health for older people.

More pointedly, a 24‑month retrospective cohort study in older adults with type 2 diabetes reported that semaglutide use was associated with muscle loss and functional decline, particularly at higher doses and in patients who already had sarcopenia. The authors emphasize individualized risk–benefit assessment and the need for monitoring and intervention.

If you’re reading this as an older adult, it may help to translate the research into plain questions to bring to your next appointment: “If I lose weight, how will we protect my muscles?” “How will we check whether I’m getting weaker?” “What would make us stop or change course?” An older adult who becomes “smaller but weaker” has not gained health — only risk.

4) Other complications: gallbladder, pancreas, vision, and low blood sugar

Gallbladder and bile duct problems can be an unexpected issue. Losing weight already increases the risk of gallstones, and GLP-1s seem to increase it even further. A large review found that using GLP-1 drugs increases the chance of gallbladder or bile duct disease, especially at higher doses, for longer periods, or when used for weight loss.

For older adults, this might present as sudden pain in the upper right side of the belly, nausea, fever, or pain spreading to the back or shoulder. These symptoms should be checked by a physician right away.

GLP-1 drug labels also warn about the risk of sudden pancreatitis and say to get medical help for severe, ongoing belly pain. The overall risk is low, but older adults may have additional risk factors, such as gallstones or high triglycerides. Severe belly pain in later life should always be checked quickly.

Then there’s the risk of blood sugar dropping too low. GLP‑1s don’t usually cause hypoglycemia by themselves, but the risk rises when combined with insulin or sulfonylureas. Semaglutide labeling warns that concomitant use with an insulin secretagogue or insulin may increase the risk of hypoglycemia and may require dose reductions of those agents.

In older adults, hypoglycemia can be particularly dangerous: it can cause falls, confusion, fainting, and cardiac stress. It’s also easier to miss, because symptoms may look like “just being tired” or “a little off today,” especially in someone who already has memory or balance problems.

Eyes and vision deserve special attention. Semaglutide labeling includes a warning about diabetic retinopathy complications and recommends monitoring patients with a history of retinopathy. Beyond labeling, post‑marketing safety monitoring continues to explore visual signals.

A 2025 analysis of FDA adverse event reporting data found a potentially elevated risk of vision‑impairment reports with semaglutide use compared with some other diabetes and weight‑loss medications, and it called for vigilant surveillance and further research. That doesn’t prove the drug causes vision loss in an individual patient, but it is enough to justify a cautious posture: new blurring, blind spots, or sudden changes deserve a same‑week medical call, not a “let’s see if it passes.”

5) Surgery and sedation: delayed stomach emptying can cause problems

GLP‑1 medications slow stomach emptying — one reason people feel full sooner. But that same effect can complicate anesthesia and deep sedation if food remains in the stomach despite standard fasting. A 2024 review describes the connection between GLP‑1 medications, delayed gastric emptying (including gastroparesis), and increased risk of aspiration during anesthesia, as well as possible effects on the absorption of other medications.

This issue has become important enough that several medical groups have created guidelines for surgery. The 2024 guidance says many people can continue taking GLP-1s, but doctors should look for higher-risk situations, such as people with stomach problems or other risks of food entering the lungs, and adjust plans as needed.

This is important for older adults because they are more likely to undergo procedures requiring sedation, such as colonoscopies, joint injections, cardiac procedures, dental work, or surgeries. The easiest and most often missed safety step is to tell every physician involved — surgeon, anesthesiologist, endoscopist, dentist — that you are taking a GLP-1 medication and when you last took it. Do not assume it will be clear in your medical chart.

6) A senior‑friendly “yes, with a plan” approach

If you’re an older adult considering a GLP‑1 (or already taking one), a safer approach often looks like “yes, with monitoring.” That means starting with function, not just the scale: tracking energy, steadiness, and strength in everyday life, not only pounds.

It also means treating hydration as a real medical concern. Ongoing nausea, vomiting, or diarrhea is not just part of getting used to the medicine. These symptoms can affect blood pressure and kidney function, especially when changing doses.

Because muscle matters so much in later life, protecting it should be part of the prescription. That can include discussing protein intake, adding a realistic strength plan (even chair‑based work or physical‑therapy guided resistance), and reassessing the medication if weight loss is accompanied by weakness, poor balance, or reduced stamina.

Older adults should also have their medications reviewed with a focus on preventing low blood sugar. If insulin or a sulfonylurea is being used, doses may need to be adjusted as appetite decreases and blood sugar improves.

Finally, it is important to take symptoms seriously. New stomach pain, ongoing vomiting, or sudden vision changes should be checked by a doctor right away. Before any procedure with anesthesia or deep sedation, make sure to tell the medical team about your GLP-1 use — do not assume they already know.

The GLP-1 medications can help some older adults, but there is less room for mistakes. Side effects can quickly lead to dehydration, frailty, falls, or problems during procedures. The safest approach is not just ‘yes’ or ‘no,’ but ‘yes, with a plan’ — one that protects hydration, nutrition, muscle, vision, and safety during medical care.

Early Detection Poses Challenge

Glaucoma may strike individuals of any age, but it is most prevalent in people over the age of 60. For Black Americans, the rate of prevalence ticks up much earlier, at about 40 years of age, and people with diabetes or a family history of the condition are also more susceptible. Because glaucoma is asymptomatic in initial stages, early diagnosis is challenging.

The disease occurs when the optic nerve and the retinal ganglion cells — which relay visual inputs to the central nervous system — are damaged; elevated pressure in the eye, or intraocular pressure, is the main culprit. When fluid accumulates in the eye, such as from overproduction or improper drainage, it increases intraocular pressure and also the risk of developing glaucoma. Symptoms appear slowly, with changes in peripheral vision occurring before forward-facing vision becomes compromised.

Comprehensive eye exams can catch glaucoma in earlier stages, as these screenings involve optic nerve examination, intraocular pressure measurement, visual field testing and risk factor assessment. Patients must be proactive about regular screenings because once vision is lost, it cannot be repaired or restored. Available therapies can stop glaucoma’s progression and generally focus on alleviating intraocular pressure, but early diagnosis remains key.

Building on Existing Diagnostic Tools

Advances in diagnostic tools can give clinicians more and better information for treating glaucoma. Optical coherence tomography (OCT), for instance, uses light-wave imaging to help assess the optic nerve’s structural integrity. More recently, OCT angiography (OCTA) has been adopted to consider the optic nerve’s support system, such as blood supply. Functional imaging may be the next wave, as it should enable clinicians to identify cells under oxidative stress and take corrective action before irreversible damage is done.

Understanding a patient’s visual field is critical to identifying ocular diseases, and virtual reality goggles are emerging as a user-friendly, portable device. Doheny Eye Institute, dedicated to vision science, is investigating VR to enhance existing field vision testing and foresees future assessments that could bypass patient response. With its predictive powers, AI should also have a diagnostic role; AI may identify factors that clinicians could overlook when determining the risk of disease, progression, and aggressiveness so that patients can be treated early and accordingly.

Treatment Options Keep Evolving

Patients have various treatment options for glaucoma and generally take one of three paths: medication, laser or surgery. In the past five years, two new medications have surfaced, each with a novel mechanism of action that is additive to clinicians’ arsenals. The rho kinase inhibitor works to lower intraocular pressure, while a nitric oxide medication has dual action, reducing pressure and improving blood flow and oxygen to the optic nerve head. Research organizations like Doheny Eye Institute are also investing in the drug delivery arena, seeking ways to reduce patient error in medication administration and improve outcomes.

Laser treatment is nothing new in treating glaucoma, but techniques and instruments are constantly being refined. Laser trabeculoplasty has gained more acceptance, and as a minimally invasive procedure, it provides relief by reducing intraocular pressure. A more recent introduction, micropulse transscleral laser therapy also relieves intraocular pressure but by delivering energy in short pulses, which appears to minimize collateral tissue damage.

Should patients be beyond medication or non-invasive procedures, incisional surgery remains an option to improve natural drainage of the eye or insert an implant to create an accessory drainage pathway. Advances in surgical procedures, implants and devices continue to be sought after in research circles.

The Future Lies in Neuroprotection

Glaucoma research is a dynamic field, and an emergent focus is neuroprotection, where treatment extends beyond decreasing intraocular pressure to intervention in the chemical pathways that lead to the death of retinal ganglion cells. This exciting area considers protective effects, such as a drug therapy that could prevent cells from dying. It also explores how cells could be resuscitated, or what interventions could return damaged cells to their full functionality. Ultimately, this field of study is working toward neuro regeneration, where neural pathways may be fully restored so that lost vision may be regained.

With continued advances in glaucoma-related research and development across the board — from diagnostics and devices to pharmaceuticals and drug delivery to laser and surgical procedures — the future for patients is looking brighter. Maintaining momentum will be key for researchers to achieve the ultimate goal and find a cure for existing and future glaucoma patients.

Over a thousand epidemiologic papers were examined, including clinical trials of weight-loss or weight-control therapies. These investigations included observational studies on cancer risk and fat excess. Because of this, the assessments focused on the dangers of being overweight rather than the benefits of preventative measures.

Studies varied in their risk assessments; most focused on adults’ body mass index (BMI), while others looked at childhood or adolescent BMI or body shape, weight or BMI changes over time, or other measures of adiposity, such as waist circumference.

The analysis considered relative-risk estimates where sufficient analyses of observational data were accessible. The absence of extra body fat, it was concluded, reduces the risk of cancer at previously described organ sites. In addition, study results point to the fact that being lean reduces the incidence of eight more cancers: gastric, cardiac, liver, gallbladder, pancreatic, ovarian, thyroid, multiple myeloma, and meningioma. Once again, however, we must understand that correlation does not equal causation. But the indicators are of concern and great interest.

If the newly introduced GLP-1 medication can control obesity, which, in turn, may reduce the incidence of cancer, researchers are now questioning whether these drugs may serve other purposes in healthcare. There is a belief that GLP-1 medication use may extend beyond obesity and weight control. What areas are they currently considering for studies with these medications?

GLP-1 for Addiction?

The World Health Organization (WHO) found that 2.6 million people die each year because of alcohol intake (or 4.7% of all deaths), and 0.6 million people die because of the use of psychotropic drugs. Men accounted for 0.4 million drug-related fatalities and 2 million alcohol-related fatalities. But while alcoholism remains a serious health hazard, there are other addictions to street or prescription drugs that are also of concern to healthcare professionals and patients.

Cocaine use disorder affects an estimated 5 million people. Worldwide, the death toll from cocaine overdoses is rising at a faster rate than that from opiate overdoses.

But there is an intriguing relationship between obesity and addiction. Substantial evidence in the literature linking obesity to substance use disorders supports a link of sorts. Studies have shown that when people are exposed to meals that are very tasty, certain hormones in the brain are triggered, which makes consuming unhealthy choices more likely.

This is analogous to what occurs in the brains of those who suffer from substance abuse disorders. Behaviors comparable to addiction to foods high in fat and sugar have led to studies employing animal models of obesity, discovering typical neurobiological features of addiction in the brain systems. The reward system that is engaged, and that perpetuates a preference for specific types of foods, may also be involved in addiction disorders.

The conclusion, currently, is that there is a viable solution for addiction through the use of the GLP-1 medications. Researchers must further investigate these specific connections and detail their interrelationships.

Since the discovery of GLP-1 medications for obesity, several off-label uses have also been shown to be useful. Researchers are actively exploring the growing number of diseases that these medications might treat, which is extremely promising.

The potential utility of GLP-1 disorders of addiction and others include: food addiction (binge eating), alcoholism, Parkinson’s disease, depression, anxiety, heart disease, hypertension, fatty liver, polycystic ovarian syndrome, chronic kidney disease, inflammation, and opiate and narcotic addictions.

Addiction regulation, inflammation reduction, dopamine pathway modulation, and insulin sensitivity are just a few of the many physiological consequences of these receptor agonists. Because of these processes, they are promising candidates for the treatment of diseases outside of their original indications.

Medical and scientific communities are highly intrigued by the prospect of GLP-1 medicines potentially treating this wide array of illnesses, but research into these uses is still in its early phases.

The future, however, appears promising as new indications come to light, and as research reveals the areas where they may be brought into a treatment regime that is successful. At this juncture, however, it is not always apparent which biological pathways are being affected and that is a remaining question for future research efforts.

According to the ADA, the diagnosed cost of diabetes in the United States is estimated to be $412.9 billion in 2022, including both direct medical costs and indirect costs like lost productivity. As the prevalence of diabetes continues to rise, costs will climb higher and higher, placing an unsustainable and unnecessary burden on our health system and economy. It points to a stark, uncomfortable realization that the biggest cost burden on the American taxpayer isn’t drugs (11 percent of the total national health spend); it is the cost of manageable disease run amuck.

While the White House and Congress rightly tout their success in lowering the cost of insulin for Americans in need, the policy victory speaks to the persistent problem—akin to closing the barn door after the horse has escaped—that more and more people are being diagnosed with or unaware of their diabetes risks. The bigger “hairy audacious goal” is to reduce the number of people with diabetes in the first place.

A Tale of Two Americas

The Type 2 diabetes epidemic is not an equal opportunity offender. It disproportionately affects racial and ethnic minorities, as well as those with lower educational attainment and socioeconomic status. This is not a coincidence; it results from systemic inequalities plaguing our health-delivery system. It speaks to the long overdue need to use PK-12 education to inform young people about healthy diets.

Black Americans, Hispanic/Latino Americans, and Native Americans bear a heavier burden of this disease because of deeply rooted social determinants of health. Access to quality healthcare, education, and economic opportunities are crucial in determining who develops Type 2 diabetes and who doesn’t.

According to the ADA: “The poorer you are in America, the less likely you are to have a grocery store within walking distance of your home. Diabetes rates are inversely related to income level, and nutrition is critical to diabetes prevention and management. Every American with diabetes and prediabetes must have access to affordable, culturally relevant food and the information they require to eat healthfully.”

At the heart of this crisis lies a fundamental issue raised for years: our relationship with food and education. The lack of basic nutritional literacy in many communities is not just unfortunate; it’s a tipping point for heart disease and diabetes. Many Americans, particularly in underserved communities, make food choices that harm their health because of strained household economics or lack of information. The food label on packaged goods is helpful to those who can translate the percentages listed into actionable decisions. Still, desperation often makes those decisions for people regardless of what the label says.

In urban and rural areas with limited access to fresh, nutritious food, food deserts are not just inconveniences but public health hazards. When the only food options available are processed, high-calorie, or convenient and tasty fast foods, we set up communities for a lifetime of health struggles.

Innovation and Public Policy: Islands of Hope

Traditional approaches are proving inadequate in the face of this growing threat. The health system needs to embrace innovative, policy- and technology-driven solutions that can reach people where they are and provide personalized support.

More than 41 million people participate in the Supplemental Nutrition Assistance Program (SNAP) and receive an average monthly benefit of $191 per person, or a little over $2 per meal. ​Roughly four out of 10 SNAP participants (42%) are children under age 18; 16% are people 60 and older, and about 12% are people with disabilities. The results are dramatic!

Children receiving SNAP benefits have better health status than youngsters who are not SNAP participants, and their households are less likely to sacrifice health care to pay for other necessary expenses. Older SNAP participants are less likely to be admitted to a nursing home or hospital than their counterparts who do not participate. It seems like common sense. Caring for the chronically ill costs taxpayers more.

Telemedicine and remote monitoring technologies offer potential avenues for diabetes management. These tools can provide real-time data to healthcare providers, allowing for more timely interventions and personalized care plans. AI-powered nutritional guidance apps have the potential to democratize access to customized meal plans, accounting for an individual’s health status, cultural preferences, and economic constraints. These tech tools can only be used as preventive and interventional extensions of the doctor’s office if third-party payers – private and public – ensure it is in the health providers’ interests. 

On the pharmaceutical side of innovation are the GLP-1 receptors – that can help millions of people struggling with obesity – among the key catalysts for the surge in pre- and Type 2 diabetes. GLP-1 receptor agonists mimic the hormone’s action, crucial in regulating blood sugar levels. But here’s the kicker: these drugs don’t just lower blood glucose; they’re a Swiss Army knife of metabolic health. However, private payers often place obstacles in the path of access. Obesity is a complex – tipping point – disease leading to diabetes, mental health challenges, heart disease, and more. Payers often will not authorize GLP-1 use for people who are overweight and have prediabetes – waiting till people (their beneficiaries) graduate to Type 2, citing cost.

The Obesity Society spokesperson Katherine H. Saunders, MD, of Weill Cornell Medicine, New York City, in an interview with Medscape, comments: “What is more expensive than Wegovy (a GLP-1 class drug)? A day in the hospital. This is a particularly important finding for health plans, employers, and any group covering the total cost of care — many of whom are concerned about the cost of Wegovy. Hopefully, this data will encourage more decision makers to recognize not only the significant health benefits associated with Wegovy but also potential cost savings.” Dr. Saunders is among the nation’s top thinkers in the field of obesity and associated conditions, and as an entrepreneur, co-founded FlyteHealth, a community of health providers who specialize in helping people manage their weight.

Health- or Sick-Care – We Must Choose a Path

The economic impact of Type 2 diabetes is staggering. The time for half-measures and incremental change is long past. We need a coordinated, multisectoral response—the health sector, industry, government, and private philanthropy—working together to address the epidemic’s foundational causes.

Five suggestions include:

1. Investing in education at the primary school level and ensuring children understand healthy food choices and have access to in-school meals.
2. Addressing social determinants of health through Federal and state policies that promote economic equity and access to quality health and education
3. Leveraging well-proven approaches in remote patient monitoring to improve diabetes intervention, detection, and management
4. Strengthening the use of Federal and state programs such as SNAP and the Child and Adult Care Food Program (CACFP)
5. Fostering collaboration between health providers, community organizations, national professional health organizations and tech companies to deploy proven solutions.

The Future We Must Embrace

Current efforts to address Type 2 and prediabetes prevention are insufficient. By acknowledging the complex relationship among social, educational, economic, and environmental factors contributing to this chronic illness epidemic, the United States private and public health system must examine drug costs; however, it can develop more effective policies and campaigns for diabetes intervention and management. 

It’s time for a mindset shift in approaching this preventable condition. We must recognize that we have, to date, given lip service and window dressing to address disparities and support the needs of children growing up without sufficient knowledge about food choices or, in the case of cash-strapped families, access to a healthy meal that reinforces what they are learning in school. Half measures were never good enough and are no longer acceptable.

Every step toward managing Type 2 diabetes – or better yet, preventing it entirely – is a step toward a healthier, more equitable society. The challenge is immense, but the ability to make a difference is possible.  There are proven delivery methods for insulin, vastly improved ways to monitor blood glucose and policies that could be tweaked to meet people’s needs.  Together, we can turn the tide on this epidemic and create a future where Type 2 diabetes is no longer a looming threat but a manageable condition.

Pay now or pay later. It’s a decision payers and policymakers must make.

Obesity is a significant public health issue that affects people of all ages, genders, and socioeconomic backgrounds. The World Health Organization (WHO) states that over one billion people worldwide are obese. This estimate includes 650 million adults, 340 million adolescents, and 39 million children.

The World Health Organization explains that obesity impacts most body systems, including the heart, liver, kidneys, joints, and reproductive system. It can lead to various non-communicable diseases (NCDs), including type 2 diabetes, cardiovascular disease, hypertension, stroke, cancer, and mental health issues. Individuals with obesity are three times more likely to be hospitalized for COVID-19.

Now comes a brain imaging study that analyzed brain differences between females and males with a high body mass index (compared with those with a normal BMI).

Obesity — Men and women have different brains

The University of California, Los Angeles (USA) researchers analyzed data from magnetic resonance imaging (MRI) scans, clinical characteristics, and medical histories. They aimed to identify sex-specific brain processes that lead to obesity. Might men and women develop obesity for different reasons?

Historical studies examined brain images to see how obesity affects eating habits. Few studies have looked to see how the brains of obese individuals might differ in males and females.

Here are the current study results:

Specific brain parts differed between males and females with a high body mass index (BMI). The researchers offer that tailoring management to an individual’s sex may be essential to combating obesity.

In other words, investigating sex as a biological variable is key to determining obesity development and management response.

Obesity — Study details

The study involved a review of data from 183 participants. Of these, 78 had a high body mass index, and 105 had a normal BMI. The researchers used several brain scan forms. They also collected survey data on early life experiences, mood, and eating habits.

Using a method known as DIABLO, the scientists tried to accurately discern differences between those with a high versus a normal BMI. They also assessed differences between males and females with high BMI.

The analysis could effectively differentiate high BMI from normal BMI participants with 77 percent accuracy. Also, males with high body mass indexes could be distinguished from females with high BMI with 75 percent accuracy.

The study discovered differences in specific brain regions when comparing males and females. These variations appeared to be related to mental health, early life experiences, and touch sense.

Women with obesity exhibited changes in emotion-related brain centers associated with higher compulsive eating levels. On the other hand, in men, brain regions related to eating behavior and obesity were linked to gut sensations linked to abdominal discomfort and hunger.

Moreover, women with a high BMI had more significant brain signatures and lower mental health scores than men. Females may be more vulnerable to developing food cravings and addictions.

My take — Obesity and sex differences in the brain

This exploration of sex differences is unusual; of 199 studies found by the researchers, only 13 examined sex differences.

Key brain signatures are changed in obese individuals, affecting how an individual views food (and food cravings), eating patterns, and obesity. By looking at how these brain patterns differ by sex, the researchers open the door to a better understanding of the pathways by which women and men develop obesity.

In summary, there are gender differences in obesity. The reasons for the variation are unclear. By better understanding how the brains of those with obesity differ from those without it, we may develop better diagnostic and management tools.

Because the study was cross-sectional (comparing one group to another), the researchers cannot establish any causal relationships. We do not know if the brain MRI differences between men and women, based on body mass index, are due to gender or BMI. There may be some other factors.

Second, the researchers could have used more accurate measures of obesity, including waist-hip ratio or fat measurements (visceral adiposity).

Finally, I don’t think this provocative study has any implications for the current management of obesity. Given that those with a higher BMI report significantly greater childhood traumas, anxiety, depression, a tendency to notice body symptoms with hypervigilance, and other chronic stressors, we need to do a better job addressing these issues.

Blood sugar levels are already routinely monitored in patients with diabetes or those at risk of developing diabetes, but the importance of maintaining stable blood sugar levels for overall health is becoming more widely recognized. Elevated blood sugar levels, even if not high enough to indicate diabetes, may be associated with an increased risk of cardiovascular disease, kidney disease, and other health problems.

As a result, tracking blood sugar levels without diabetes or pre-diabetes may become a tool for managing both disease and wellness. Or perhaps, availability of broader data sets can foster research examine blood glucose levels and trajectory to offer new insights into the pathophysiology of related diseases at earlier points in time.

Digital health has often offered monitoring solutions that reside in the consumers hands (or wrists). And this has certainly been a mixed blessing.  Some tools have provided valuable insights into health.  Yet some have become merely a source of arbitrary information that cannot be translated into clinical value.  Further, this added burden to healthcare providers may further preclude adoption.  But as innovation has taught us, the next big thing can often be close at hand.  The emergence of continuous blood glucose monitoring (CGM) has been transformative for patients.  And the new data sets have given scientists powerful insights into glucose kinetics and insulin administration.   And these insights maybe game-changing with the global concerns of obesity and metabolic syndrome.

Your watch is becoming a value tool in wellness and disease management.  And that value is only beginning to be realized and implemented.

Risk factors for men

Our previous article on American health found that men have worse cardiometabolic health than women. This can be chalked up to an obesogenic and sedentary lifestyle — a lifestyle consisting of behaviors such as prolonged sitting, lack of physical activity, poor diet, and short sleep duration. These can all affect the regulation of our body’s insulin and contribute to the development of diabetes and other cardiometabolic diseases.

Unfortunately, men also tend to be more exposed to unhealthy vices. According to the WHO and the National Institute on Alcohol Abuse and Alcoholism (NIAAA), 36.7% of all men are tobacco users, and 8.3% are alcohol users, as opposed to 7.8% and 4.5% of all women.

Smoking and alcohol abuse have long been proven to be tied to type 2 diabetes. Regular heavy drinking can cause chronic pancreatitis and higher caloric counts in men. Additionally, nicotine makes it harder to control your blood sugar, which is why smokers are 30-40% more likely to develop type 2 diabetes than nonsmokers.

Besides these social mechanisms, there are biological factors that program men to be more vulnerable to type 2 diabetes. Research has found a link between testosterone and the development of type 2 diabetes, wherein low testosterone levels in men can increase visceral fat deposition in the body. This contributes to the reduced response of insulin to glucose. Because one in six males has low testosterone, this leads to a dramatic increase in diabetes risk.

Moreover, men are further disadvantaged in the distribution of fat because of how their bodies naturally accumulate excess fat around the abdomen. Abdomen fat raises the risk of insulin resistance more than any other type of body fat. All of these risk factors subject men to higher chances of type 2 diabetes, making them almost twice as likely to develop type 2 diabetes as women.

Mitigating the risks

Fortunately, healthy lifestyle choices can help prevent type 2 diabetes and overcome biological predispositions. Maintaining a healthy weight can improve one’s cardiometabolic health and thereby delay the progression from prediabetes to type 2 diabetes.

To start, men can alter their diets to primarily include foods lower in fat and calories and higher in fiber. In order to nurture a healthy relationship with food, weight loss programs based on nutrition science can consider an individual’s genetic susceptibility to diabetes and work around it by introducing customized meals that fit a user’s lifestyle and budget. This makes it easier for an overweight male to make the shift away from vices like alcohol and salty or greasy comfort foods and instead form lifelong habits that prioritize his health.

The same logic can be found in introducing exercise to someone with a sedentary lifestyle. Research has found that exercise tailored to an individual’s body is an effective way to address diabetes. Taking the time to understand how your genetic background determines your response to exercise can lead to faster results and thereby increase your motivation to continue the program.

An early assessment of your risk factors is often the best way to prevent type 2 diabetes, or at least stop it from worsening. By starting your lifestyle changes today, you can decrease these risks and improve your overall condition for a longer and healthier life.

Racial bias prevents many people from attending adequate schools, entering promising careers, and accessing adequate healthcare. This bias also affects where they can find suitable housing, and that housing may contribute to health difficulties brought on by pollution or vermin infestation. The situation, undeniably, is untenable, and anyone who believes in human rights will find each of these impediments anathema.

All the above is clear, but taking the situation two steps further will reveal the hidden extent of the potential damage raining down on anyone who is a victim of this bias. And, most disturbing, this further damage to health happens in the medical realm.

Socioeconomic factors lead to health risks such as asthma, and the need for ongoing, accurate treatment for asthma is mostly with inhalers. The condition is so severe that frequent emergency treatment is sought. Compared with white people with asthma, African American people with asthma are five times more likely to visit the emergency room for symptoms.

One of the inhalers of choice for asthma is albuterol, and here, again, there is a problem with treatment. A study of over 1,400 children revealed a genetic lack of appropriate response to this drug in some patients. And problems in sampling were apparent. We and others have documented the implications and challenges posed by the lack of non-European study populations in biomedical research. Sampling bias is at the heart of one major problem in device engineering.

Once asthma treatment is sought, there still needs to be a resolution to the underlying measurement problem. While in the ER, how is the oxygen level of these patients determined? The usual initial route is to get a quick level using an oximeter slipped on a finger. It’s a rapid and supposedly accurate measure of how much oxygen the patient has in their blood; vital information.

Who questions the oximeter readings? The assumption is that the task is accurate because the device is FDA approved, made by a reputable company, and has been used for years in hospitals. But that conclusion is patently false.

The validity of the readings was made primarily on persons of European descent. How accurate would they be on anyone who did not meet that criterion? The answer would seem obvious.

Studies dating back to 2005 show pulse oximeters tend to overestimate the amount of oxygen a patient with darker skin may actually have in their blood. It’s simple physics: Melanin in skin absorbs some of the light the devices analyze to make their readings. The darker the skin, the more melanin there is, and the less light passes through.

If the readings are wrong, how does that have an impact on treatment? Again, no question that there is a bias in oxygen levels leading to changes in medical care.

The FDA issued an alert on oximeters, but did everyone dispose of their older, inaccurate devices in healthcare and the home? Other factors affect these readings, including poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and use of fingernail polish.

NASA had developed guidelines and devices for more accurately measuring blood oxygen, but the corporation involved in it changed its marketing direction and the device was dropped.

We know that the disturbing use of oximeters tested in Japan (with a relatively homogenous population) may lead to delays in treatment in persons with darker skin. How is this permissible? It’s not, and the NASA devices should be considered again.

Ultra-processed foods are industrial formulations of substances made from foods (fats, oils, sugars, starch, and protein isolates) with little or no whole foods. Manufacturers often add colors, flavors, emulsifiers, and other additives for cosmetic enhancement and other non-essential purposes.

The result? We have lots of low-cost production products that are convenient and taste great, rather than unprocessed (or minimally processed) foods.

We know that ultra-processed foods can harm our health, leading to chronic conditions such as high blood pressure (hypertension), diabetes, and obesity. A recently reported study from Brazil illustrates another peril: Ultra-processed foods (UPF) consumption appears to be linked with a significant increase in all-cause premature, preventable deaths.

Defining ultra-processed foods

When it comes to my local grocery store, I sometimes fantasize about placing a big sign at the ends of the aisles of processed foods shouting, “avoid this area.” You may have heard a newer term, ultra-processed foods. We are seeing increasing evidence linking this food category to significant health risks.

So, you may wonder, what is the difference between processed and ultra-processed foods? Processed food is simply one altered from its original form.

The International Food Information Council defines processing as “any deliberate change in a food that occurs before it is ready for us to eat.” Examples of processed foods include pasteurized, heated, canned, or dried ones. Some consider refrigerated foods to be processed.

Most foods have processing to some extent. Processing does not always make a given food less healthy. Researchers created a classification scheme to understand processing better.

• NOVA Group 1. Minimally processed and unprocessed foods. Vegetables, fruits, grains, beans, and nuts fall into this category. These foods may have gone through roasting, boiling, or pasteurization to increase shelf life or make them safe to eat.
• NOVA Group 2. Processed culinary ingredients obtained directly from group 1 foods or nature. Examples include olive oil, maple syrup, and salt. Group 2 foods are mostly substances used to prepare and cook group 1 foods.
• NOVA Group 3. Processed foods, including items made by adding ingredients like salt, sugar, or other substances from group 2 to group 1 food. Examples include fresh bread, fruits in syrup, and cheese.
• NOVA Group 4. Ultra-processed foods. These contain little, if any, of the foods or ingredients from group 1. These items are meant to be convenient, hyper-palatable, and low-cost and are usually high in sugars, refined grains, fats, preservatives, and salt.

Let’s look more closely at NOVA Group 4, the ultra-processed foods. As you can see from the following examples, foods in this group usually have substances you and I don’t use when we cook at home.

Examples of ultra-processed foods

Ultra-processed foods include colorants, flavorings, modified starches, hydrolyzed proteins, hydrogenated oils, artificial sweeteners, and bulking agents. And I would be very remiss if I didn’t include my bete noir, high fructose corn syrup.

While reasonable individuals may disagree about classifying foods as highly processed, the guidelines appear reasonable.

Examples of ultra-processed foods include sugary beverages such as carbonated soft drinks, energy drinks, fruit punch, and sugar-laden coffee drinks.

Reconstituted meat products (such as hot dogs and fish sticks) fall into the ultra-processed category, as do frozen pizza and TV dinners. If you had sweet or savory packaged snacks such as cookies or chips, you had highly-processed foods. Not surprisingly, candies fall into this food group, too.

Other culprits include sweetened breakfast cereals, baking mixes (such as cake, brownie, or cookie mixes), packaged buns, and bread. I recently wrote about protein bars (and shakes).

Other problematic foods include ice cream, sweetened yogurt, cocoa mixes, instant soups, and boxed pasta products. Finally, margarine and ultra-processed spreads (for example, sweetened cream cheese) are NOVA Group 4 foods.

In summary, as Healthline nicely explains:

"Highly processed, or ultra-processed, foods contain few or no minimally processed or unprocessed ingredients and tend to be higher in calories, salt, fat, and added sugars. Plus, they contain additives such as flavor enhancers and thickeners."

Ultra-processed foods and premature death

Scientists designed a study to estimate premature deaths due to the consumption of ultra-processed foods in Brazil. The researchers estimated that approximately 57,000 individuals between 30 and 69 died prematurely from ultra-processed food consumption.

The Brazilian study is the first to estimate how ultra-processed food consumption impacts longevity. Researchers relied on a previous analysis, which compared the mortality risk of individuals consuming copious processed food to those who ate relatively small amounts of it.

Why age 30 to 69? The World Health Organization (WHO) considers death from non-communicable diseases premature at those ages. Here are the disturbing findings:

"If all adults in Brazil ensured that ultra-processed food made up less than 23 percent of their daily calories, the country might see around 20,000 fewer premature deaths annually. Most Brazilians are below that threshold, but a quarter of the country’s adult population gets up to half of its daily calories from ultra-processed food."

Before we in the United States point fingers, I remind you that, on average, ultra-processed food makes up around 57 percent of daily calories. The study’s lead author volunteers that “it is very likely that heart disease is among the main factors” contributing to these premature deaths. Diabetes, cancer, obesity, and chronic kidney disease may play a role as well,” he adds.

Research links ultra-processed food consumption with other negative health outcomes, including diabetes, cardiovascular disease, cancer, and cognitive decline.

Finally, this is not the first study to demonstrate an association between ultra-processed food consumption (in large amounts) and a higher overall risk of death. An Italian study reported similar findings.

In addition, previous studies showed that ultra-processed food consumption is linked to other health problems, including an elevated risk for diabetes, cognitive decline, heart disease, and cancer.

Completely avoid ultra-processed foods?

The new study adds to a growing scientific literature linking ultra-processed food consumption to chronic diseases and premature death. The researchers remind us that a healthy, balanced diet should be centered on minimally processed fresh foods when possible. I would steer away from too many ultra-processed foods.

Do we in the United States need policies that disincentivize ultra-processed food consumption? Nutrition education might be one component, as is improving access to healthy foods in so-called food deserts.

It is not essential to dodge all highly processed foods to enjoy a healthy life. I eat for joy and as a part of social engagement. Oh, I like desserts that incorporate dark chocolate. Still, I try to consume such foods in moderation and work hard to increase my consumption of whole, minimally processed foods.

Is this approach easy for me? No, but having grapes, apples, and nuts within reach makes it easier. While I recognize that the term is overly broad, I prefer a Mediterranean diet pattern. And the occasional chocolate dessert.

Thank you for joining me today. I hope that you have a joy-filled day.

America’s changing diet and physical fitness

How we eat looks a lot different today compared to 40 years ago in terms of how much and what we consume. The Pew Research Center analyzed data from the U.S. Department of Agriculture (USDA) and found that in 2010, Americans ate around 23% more calories than in 1970. That adds up to about 2,481 calories a day, more than the suggested 1,850 to 2,000 calories adults need to maintain their current weight. The Pew report also shows that we are eating less meat, dairy, sweeteners, fruits, and vegetables today than in 1970.

Along with diet, exercise has also changed over the years. The field of exercise science began in the 1800s to better the health of working-class people using dance and sports. By the end of World War II, more Americans worked in factories, resulting in less strenuous activity than farm work. The sedentary lifestyle culminated in the invention of the television, which kept more people at home and less active.

In the 1950s, a global study revealed that American children were less fit than their counterparts in other countries. The study prompted the establishment of the President’s Council on Youth Fitness. The council began to take shape under the John F. Kennedy administration, launching a national campaign on physical fitness and physical education curriculum for schools across the country. The council and its programs are credited with changing public attitudes and improving fitness nationwide.

Does exercise work for weight loss?

You may wonder how exercise fits into a weight loss program. Unfortunately, you probably will not see significant weight loss from exercise alone. Many people overestimate the number of calories they burn by exercising, which can lead to misjudging the number of calories they can consume. Exercise may also trigger hunger or the idea that you can splurge calories on a treat because you went to the gym. Research shows that changes to your diet – eating fewer calories and more nutrient-dense food – are a better strategy for long-term weight loss.

While it may not help you lose weight, exercise still offers many potential health benefits, like better sleep, lower anxiety, and weight maintenance. In recent years, Marissa Quinones of Grand Prairie, Texas, has prioritized exercise as part of her daily life. Quinones, the director of medical affairs strategy for a biopharmaceutical company, began participating in fitness challenges through Women of Color in Pharma (WOCIP), a network of more than 900 female professionals working in the pharmaceutical industry. Each season, WOCIP hosts the Nike Run Club, an 8-week challenge that encourages members to log at least 25 hours of walking, running, or jogging miles per month. The challenges have fostered a spirit of friendly competition in Quinones, and a love of walking, hiking, and the outdoors.

“I prefer to be out in nature. It helps to clear my mind and get ready for the day,” she says. Compared to indoor exercise, walking outdoors also helps her focus more on enjoying exercise and less on the time spent doing it. ”I’m not really good at the treadmill. It wasn’t fun for me.”

Quinones walked almost 250 miles in 2021; by September 2022, she had already surpassed that number, with the goal of reaching 300 miles by the end of the year. Beyond the physical benefits, she views walking and other exercise like yoga as self-care for her mental health. Science confirms this idea – an extensive study of 1.2 million people living in the U.S. published in The Lancet Psychiatry found a meaningful link between physical exercise and improved mental health, depending on the type, duration, and frequency of the exercise.

What are the different types of diets, and do they work?

Despite gains in physical activity, more Americans have become overweight or obese over nearly 50 years, which has led to the rise of a culture of dieting. An imbalance between the calories you consume and the number your body burns causes obesity. Losing 5% to 10% of your body weight can lower blood pressure, triglycerides, and blood sugar. Dieting for weight loss usually involves including more of a particular food or food group while excluding others. We use a wide variety of methods to shed pounds, from low-carb, high-protein diets, to fasting and cutting out all animal products. But which ones actually work to lose weight and keep it off? First, it may be helpful to look at the different types of diets. Most fit into one of three categories:

Controlling macronutrient content. This involves managing the nutrients you consume. For example, eating more protein and fewer carbohydrates on the Atkins diet. Or diets that require you to cut back on certain types of fat.

Restricting or eliminating certain foods. Vegan, paleo, gluten-free, and Mediterranean diets fall into this category. They all require you to stop eating specific foods or food groups.

Controlling the timing of when you eat. Many people use intermittent fasting as a way to lose or control weight. This is when you stop eating and drinking for a certain period. Common types of intermittent fasting include periodic fasting, alternate day fasting, time-restricted feeding, and religious fasting.

Scientists have examined whether these diets are effective for weight loss and maintenance. A 2019 study from a researcher at Harvard Medical School looked at several popular diets and eating methods. In the short-term, high-protein, low-carb diets and intermittent fasting could help “jump start” weight loss and boost the amount of weight you lose, according to the study. But researchers caution that these diets may come with side effects such as weakness and headaches.

Over an extended period, the type of diet you choose may not matter as much. Research shows that different diets resulted in similar amounts of weight loss. The bottom line is that no one way of eating works universally for weight loss. What matters most is the quality of your food, burning more calories than you consume, and sticking with a diet for the long term.

To lose weight and keep it off, experts recommend lifestyle changes such as eating fewer calories, more nutritious foods, and participating in physical activity. It may also require things like therapy, medication, or even weight loss surgery.

A note on BMI

It’s also important to note that although many doctors and scientists use body mass index (BMI) to measure whether a person is overweight or obese, it’s not a definitive test. It is a single measure in a larger picture of your overall health.

Plus, BMI definitions are based on white bodies. Race and ethnicity can determine the makeup of your body, including body fat percentage and amount of muscle mass. This means BMI may be a less accurate measure for some people of color. Your doctor should also look at other things like blood pressure, cholesterol, and blood sugar to get a more detailed view of your health.
