In this episode, let's talk about stress eating, also called emotional eating. It's when you eat in response to emotions rather than physical hunger. It's usually a way to cope with stress, anxiety, sadness, boredom, or even excitement.

Why does it happen? Stress triggers the hormone cortisol in our body, which increases appetite and cravings, especially for sugary, salty, or high-fat foods. Eating releases dopamine, the brain's feel-good chemical, giving temporary relief from emotional discomfort. Once your brain recognizes this pattern and associates food with pleasure and comfort, it forms a habit loop. Signs you might be stress eating include eating suddenly and urgently without much thought, craving specific comfort foods rather than balanced meals, eating even when you're full, and feeling guilt, regret, or sluggishness afterward.

How do you break the cycle? First, pause and check for hunger signals. Ask yourself: am I really hungry or am I seeking comfort? Identify your triggers by keeping a journal of what situations or emotions spark eating urges. For example, many women crave sugar during the premenstrual phase. Then find alternative coping mechanisms like taking a walk, deep breathing, stretching, listening to music, or talking to a friend. Managing stress proactively through regular exercise, good sleep, and mindfulness practices like meditation or prayer reduces cortisol levels over time. Creating a supportive food environment also helps: keep tempting trigger foods out of immediate reach and stock easy, healthy snacks like dates, nuts, or dark chocolate instead of cookies.

The bottom line: think of your emotional hunger like a smoke alarm. It's a signal that something's off emotionally, and food is just one possible fire extinguisher. You can choose other options that won't leave a mess behind or feelings of guilt afterward.

In this episode, I'm talking about glycemic index. The glycemic index is a system that ranks carbohydrate foods based on how quickly they raise your blood sugar levels after being eaten. The scale typically ranges from 0 to 100, with higher values indicating foods that cause a rapid increase in blood glucose.

Imagine your body as a fireplace and food as the logs you throw in it. The glycemic index tells you how quickly the food will burn. High glycemic index foods (70 or above) cause a rapid spike in blood glucose. They're often low in fiber and quickly digested and absorbed. This food burns like dry kindling: quick energy, but the flames die down fast, which means you'll feel hungry or tired sooner. Examples include white bread, sodas, sweetened coffees and teas, sugary snacks, and many processed foods. Medium glycemic index foods (56 to 69) cause a moderate increase in blood glucose, burning at a steady pace. Examples include whole wheat products, sweet potatoes, sweet corn, bananas, and some types of rice. Low glycemic index foods (55 or less) cause a slow, gradual increase in blood glucose. Examples include most fruits, vegetables, legumes, whole grains, apples, and oats.

Why does it matter? Stable blood sugar equals steady energy and fewer crashes. Low glycemic index foods help maintain steady blood sugar levels, leading to better satiety and easier weight management because they keep you fuller for longer. Diets rich in low glycemic index foods are also better for your heart, helping manage cholesterol levels and reduce the risk of cardiovascular disease. Factors that influence the glycemic index include the type of carbohydrate, fiber content, preparation and cooking methods (al dente pasta has a lower GI than overcooked pasta), ripeness of fruits (ripe bananas have a higher GI than unripe bananas), and fat and protein content (combining carbs with fat or protein slows digestion and lowers the GI).

The bottom line: understanding the glycemic index can help you make informed choices about your diet, particularly if you're managing blood sugar levels or optimizing energy throughout the day. Our goal is to mostly consume low or moderate GI foods, or combine high GI foods with fat and protein to slow digestion.

In this episode, Dr. Deepti Sharma sits down with Erica Rooney from Walk West to pull back the curtain on why this podcast exists — and what drives her work in obesity and lifestyle medicine.

You'll hear Dr. Sharma get personal about the patient story that changed everything, the 30-year-old with undiagnosed diabetes who passed away suddenly, leaving behind young children. That moment shifted her focus from treating illness to preventing it — and it's the reason she's here today.

This conversation covers the real stuff: how to fit exercise into an impossibly busy life (spoiler: gardening counts), why mental health is the starting point for all health changes, the two core nutrition principles that actually matter, and how to stop treating movement like a separate chore on your to-do list.

Dr. Sharma also tackles the stigma around obesity head-on — why it's a chronic neurohormonal disease rooted in genetics and biology, not a moral failure. And why creating a safe, shame-free space for her patients is the foundation of everything she does.

If you've ever felt overwhelmed by conflicting health advice, stuck in patterns you can't break, or like you're failing because you "know what to do but can't do it" — this episode is for you.

In this episode, we're talking about metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO). These terms describe different metabolic profiles in people with obesity. Despite similar BMI, these two categories differ significantly in terms of their risk for developing obesity-related complications like cardiovascular disease, type 2 diabetes, and other metabolic disorders.

Individuals with metabolically healthy obesity have a BMI in the obese range, but they don't exhibit the metabolic complications typically associated with obesity. They have normal blood pressure, normal insulin sensitivity, normal blood glucose and cholesterol, lower levels of visceral fat (fat around internal organs), more subcutaneous fat (fat under the skin), and lower levels of inflammation. Although these individuals are at lower risk for metabolic complications than their metabolically unhealthy counterparts, they're still at higher risk than individuals with normal BMI. And over time, they can transition to metabolically unhealthy obesity.

Metabolically unhealthy obesity is characterized by elevated blood pressure, fatty liver, high cholesterol, borderline diabetes, elevated fasting glucose, higher levels of visceral fat, chronic inflammation, and insulin resistance. Individuals with MUO are more prone to develop obesity-related complications like type 2 diabetes and cardiovascular disease.

The bottom line: understanding the difference between MHO and MUO helps us tailor medical and lifestyle interventions. While metabolically healthy obesity might suggest a lower immediate health risk, it does not mean there's no risk at all. Both groups benefit from lifestyle changes like improved diet, increased physical activity, and weight management. From a treatment standpoint, metabolically healthy obesity is the right time to intervene and prevent metabolically unhealthy obesity. Our goal as physicians is to intervene before microvascular damage starts.

Diagnosing and treating obesity is really challenging due to a variety of barriers that can be broadly categorized into patient-related, healthcare provider-related, and systemic barriers. Let's break them down.

Patient-related barriers include stigma and shame, which deter people from seeking help. Lack of awareness means some don't recognize they have obesity or underestimate the health risks. Psychological factors like depression, anxiety, and eating disorders complicate treatment. And misinformation makes it difficult to know what strategies are effective and safe. Healthcare provider-related barriers include lack of adequate training in obesity management, bias and stigma within the healthcare system, time constraints in busy clinical environments, and communication challenges because discussing weight is a sensitive topic.

Systemic and environmental barriers are significant. Insurance coverage for obesity treatment is often inadequate or nonexistent. Geographic, economic, and cultural barriers limit access to healthcare providers, healthy food options, and safe places for physical activity. Social determinants of health like poverty, education level, and food insecurity make it difficult to adopt healthy lifestyles. Cultural perceptions also play a role. In some cultures, higher body weight is not viewed negatively or is even considered desirable. For example, in the Indian community, an obese child is often considered a healthy child. Treatment-specific barriers include long-term adherence challenges, the complexity of obesity as a multifactorial condition, and side effects or complications from medications and bariatric surgery.

The bottom line: overcoming these barriers requires education and awareness to reduce stigma, provider training to improve care, policy and systemic changes to expand insurance coverage and access to healthy foods, and patient-centered care that tailors treatment plans to individual needs and provides ongoing support. By addressing these barriers, the healthcare system can more effectively diagnose, treat, and manage obesity, leading to better health outcomes for individuals and communities.

Obesity is one of the most complicated diseases we face today. By the time people walk into my office, they've already tried multiple diets, cleanses, detoxes, and exercise programs, and they often feel frustrated or defeated. So how do we begin? Today, I'll walk you through how I approach the initial workup in my practice and why it matters.

Every visit starts with the basics: weight, height, BMI, blood pressure, and heart rate. Then I assess for conditions that often accompany obesity like diabetes, high blood pressure, high cholesterol, sleep apnea, PCOS, metabolic syndrome, hypothyroidism, mood disorders, and even eating disorders. Obesity rarely stands alone. It's usually tied to other medical conditions that must be recognized if we're going to make real progress. I also use tools like DEXA scans or InBody scans to measure muscle mass, fat mass, body fat percentage, and basal metabolic rate, because BMI alone doesn't tell the whole story.

History taking in obesity is about hearing someone's story. I ask about the age of onset, traumas, stressors, or life events tied to weight gain like pregnancy, menopause, infertility treatments, quitting smoking, depression, or grief. We go over prior weight loss attempts, screen for eating disorders and substance abuse, review family history, and assess medications, because some drive weight gain and can often be adjusted. I also look closely at daily eating patterns, food choices, physical activity, mental health, and sleep, because poor sleep or untreated depression can sabotage any weight loss efforts.

The bottom line: by the end of this initial workup, I have a clear understanding of the genetic, environmental, psychological, and physiological factors driving someone's weight journey. This helps me tailor a plan that's realistic, compassionate, individualized, and sustainable. My role is to be a partner, not a judge. Struggling doesn't mean failing. In the next episode, we'll talk about how I build treatment plans and why obesity care requires a multidisciplinary team combining lifestyle, medications, psychology, and sometimes surgery.

So far in this series, we've explored the biology of obesity: genetics, hormones, the gut-brain axis, and set point theory. But biology isn't the whole story. The world we live in, our environment, our communities, and daily stresses shape health in very powerful ways. And if we want to change the story of obesity, we can't just focus on the individual. We have to focus on the environment. This is where advocacy comes in.

Environmental and social factors affect almost every health choice we make: access to affordable, healthy food, socioeconomic status, the rise of desk jobs and reliance on cars, psychological stress and mental health, inflation and financial strain, work and family obligations, quality of sleep, home environment, workplace culture, relationships, exposure to endocrine-disrupting chemicals through cleaning agents and detergents, and the health of your community. Are there grocery stores nearby? Safe parks for walks? Fitness centers? Every one of these factors influences energy balance, appetite, stress hormones, and ultimately weight.

This is why obesity cannot be explained by "eat less, move more." It's not just about calories or willpower, it's about context. If someone lives in a neighborhood without safe sidewalks, works two jobs to make ends meet, sleeps only five hours a night, and has little access to fresh food, how can we expect them to succeed with a "just diet harder" approach? True health requires looking at the whole person. Policy change can improve access to healthy foods in underserved communities. Urban planning can create safe parks, bike lanes, and walkable neighborhoods. Workplace reform can reduce stress and support healthier lifestyles. Public health investment can expand community fitness centers and green spaces.

The bottom line: obesity is not simply a biological disease. It's also an environmental and social one, which means the solutions must go beyond medicine. They need to come from community, policymaking, and advocacy. If we truly want healthier communities and to reverse the epidemic of obesity, we must fight for environments that support good health, not undermine it. This wraps up our deep dive into the pathophysiology of obesity. Next episode: we'll shift gears into the workup and treatments, from lifestyle interventions to breakthrough medications like GLP receptor agonists.

Meet Sarah. Over the last decade, she's tried everything: keto, intermittent fasting, juice cleanses, low-fat diets. Every time, the pattern is the same. She loses 20 pounds, and within months the weight creeps back. Sometimes she ends up even heavier than before. If you've ever felt like Sarah, you're not alone. This cycle of weight loss followed by weight regain is so common it has a name: yo-yo dieting or weight cycling. And the reason it happens isn't about lack of willpower or failure. It's about biology.

When you follow a strict low-calorie diet, you can absolutely lose weight at first. But behind the scenes, your body detects what it perceives as a threat to survival. As soon as fat mass drops, the brain's regulatory systems respond. Hunger hormones like ghrelin go up. Satiety signals like leptin drop. Energy expenditure decreases, you feel more tired, and you burn fewer calories even at rest. Cravings intensify, especially for calorie-dense foods. That's the set point theory in action. The body fights to restore fat mass, just like it would restore red blood cells after a blood donation.

Research shows that after weight loss, hunger signals remain elevated for weeks, even months. The drive to eat stays high long after the diet has ended. This explains the weight regain because the body is defending a higher set point. Repeated cycles of weight loss and regain are harmful both psychologically and metabolically. Each cycle increases fat storage efficiency, meaning you end up with slightly more fat mass. It stresses the pancreas and insulin pathways, worsening insulin resistance. And it creates shame, frustration, and loss of trust in weight loss methods, when in reality it's the physiology that's broken, not the person.

The bottom line: yo-yo dieting isn't a personal failure. It's a body defending its fat mass through powerful biological systems. The challenge and the hope lies in finding ways to reset those systems, and that's why newer medications in obesity medicine are so useful. They help people lose weight sustainably by reregulating energy balance, not just fighting against biology. Next episode: we'll talk more about these newer treatments.
