Weight and Metabolism

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.🌐 Learn more at weightandmetabolism.com

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.🌐 Learn more at weightandmetabolism.com

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.🌐 Learn more at weightandmetabolism.com

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.🌐 Learn more at weightandmetabolism.com

If you've ever lost weight on a diet only to see it creep back within months, you're not alone. Your experience reflects one of the most important theories in obesity science: the set point theory. Our bodies love balance, what scientists call homeostasis. Just like we regulate blood pH and body temperature very tightly, we also regulate fat mass. It's all about biology.The set point theory suggests that each of us has a biologically determined range of fat mass that the body naturally tries to maintain. When you lose weight below that range, your body fights back. Hunger rises, metabolism slows, and cravings increase. But here's the problem: in obesity, this regulation becomes dysregulated. The set point shifts upwards. Instead of defending a leaner fat mass, the body defends a higher one. Think of it like a thermostat stuck on the wrong setting.A landmark study in the New England Journal of Medicine demonstrated this vividly. After eating a meal, hunger signals normally dip, then rise again four hours later. But in people on low-calorie diets, hunger signals stayed elevated well beyond the meal, even weeks after weight was regained. In other words, the body fights to restore the fat mass long after the diet plan has ended. This is why yo-yo dieting is so common.The bottom line: obesity is a disease. This fat mass being a regulated phenotype, just like body temperature or blood pressure, occurs when the regulation system is disrupted and the set point has shifted upwards. The challenge is not just about eating fewer calories or exercising more, but about finding ways to reset the set point and restore healthier regulation of fat mass.

Energy balance sounds simple: calories in versus calories out. But it's actually a delicate conversation between the gut and the brain, orchestrated by the hypothalamus. Your brain and gut are in constant dialogue through the gut-brain axis, and this is the "neuro" piece of neurohormonal regulation.For most of human history, diets were simple and unprocessed. Then came urbanization, industrial food systems, seed oils, high-fructose corn syrup, and ultra-processed foods engineered to taste irresistible. This shift fundamentally altered our energy balance physiology.Here's the key: the chemical nature of calories matters. A small bag of chips has 150 calories. A medium apple has 150 calories. But chips cause a rapid blood sugar spike, insulin surge, sharp crash, and quick cravings. An apple causes a steady rise, slower decline, no crash, and no immediate craving. Same calories, completely different impact.This is why re-regulating energy balance physiology is the cornerstone of successful weight management. It's not just about reducing calories. It's about choosing foods that work with your body's signals, stabilize blood sugar, and keep the gut-brain axis balanced. The success of any weight loss intervention depends on re-regulating this disrupted physiology.🌐 Learn more at weightandmetabolism.com

When people say "I'm doing everything right, but the weight won't come off," the answer often lies in insulin resistance.Insulin is the key that unlocks your cells so glucose can enter. Once inside, your body can burn it for energy, store it as glycogen, or convert it to fat. In a healthy system, this works seamlessly. But here's where things go wrong.Insulin Resistance:When you constantly eat calorie-dense meals (sugar, sodas, refined carbs, fast food), each meal spikes your blood sugar and causes a surge in insulin. Keep doing this, and your cells get tired of insulin knocking at the door. Think of it like a rusty lock. The key doesn't fit as smoothly anymore. It has to knock harder and harder to get glucose inside.That's insulin resistance. Glucose is stuck in the blood. Insulin is working overtime. And yet, more insulin keeps coming.At first, your pancreas compensates by pumping out more insulin. But over time, it burns out. You start noticing borderline diabetes, then type 2 diabetes, where the pancreas can't keep up anymore.Why Insulin Matters for Weight:Insulin isn't just about blood sugar. It's an anabolic hormone that signals the body to store fat and increase hunger. When insulin levels are constantly high, biology is tilted toward storage, not burning. This is why women with PCOS or those in perimenopause or menopause often struggle with weight.The Bottom Line:Insulin is the gatekeeper for glucose and the driver of fat storage. When it works well, energy flows smoothly. When resistance sets in, the entire system breaks down.Next episode: We'll explore gut hormones like GLP-1, GIP, and PYY, the ones now being harnessed in Ozempic and Mounjaro.🌐 Learn more at weightandmetabolism.com

Obesity isn't just about food and calories. It's about a highly complex network of hormones that tells you when to eat, when to stop, and how much energy to burn. When that system gets disrupted, everything changes.The Key Hormonal Players:Leptin tells your brain "we have enough energy, stop eating." But in obesity, the brain stops listening (leptin resistance), so you feel hungry even when you're not.Ghrelin is the hunger hormone. After weight loss, it spikes higher, driving cravings and making weight regain more likely. This is why hunger increases when you're trying to lose weight. Your body thinks you're starving.Insulin regulates blood sugar, but when you become insulin resistant, it promotes fat storage.Cortisol is the stress hormone. Chronic stress drives overeating and belly fat accumulation.Together, these hormones create a tug of war that's incredibly difficult to win when the system is out of balance.Why Your Body Fights Weight Loss:When you lose weight, your body fights back. Hunger increases, metabolism slows down, and weight starts creeping back up. Why? Because your body views weight loss as a threat to survival.Fat Tissue is an Active Organ:Fat isn't just extra weight. It's an endocrine organ that produces 600+ signaling proteins (adipokines) that influence appetite, insulin sensitivity, inflammation, and chronic disease risk. When fat mass increases, it creates a hormonal storm that reshapes your entire metabolism.The Bottom Line:Genetics set the stage. Environment pulls the trigger. But the final pathway is elevated fat mass and disrupted neurohormonal signaling. That's why weight loss is so hard, and why treatments targeting hormones (lifestyle, medications, surgery) are critical.Next episode: We'll dive deep into leptin.🌐 Learn more at weightandmetabolism.com

Let me start by explaining what "pathophysiology" actually means — because this word gets thrown around in medicine all the time, and it's worth understanding.Physiology is how the body normally works (your heart pumps blood, your lungs bring in oxygen). Pathophysiology is the story of what happens when things go wrong — the behind-the-scenes explanation of how disease disrupts normal function.Now, let's apply that to obesity.Why do some people struggle with their weight more than others? Is it willpower? Lifestyle choices? Or is it something much deeper?The answer is overwhelmingly genetic.Studies of twins have shown that about 70% of our tendency to gain weight is genetic. If you've ever noticed that everyone in a certain family has the same body type, you're not imagining it — that's biology at work.This insight traces back to the groundbreaking work of Dr. Albert Stunkard in the 1980s. At the time, obesity was considered a behavioral problem — a matter of willpower. Doctors in the 1800s even described it as a "disorder of self-control."But Dr. Stunkard challenged that view. In one famous study, he looked at over 500 adopted adults and compared their body weight to their adoptive parents (the ones who raised them, cooked their meals, set their household habits) and to their biological parents.The results? There was no correlation with the adoptive parents. Instead, the adoptees' body weights closely matched their biological parents.He followed that up with twin studies — hundreds of pairs of twins, some raised together and others apart. And again, their BMI was almost identical, regardless of whether they grew up in the same home or separately.This was powerful evidence that genetics, not environment, was driving body weight.But does that mean genetics is all to blame and environment doesn't matter? Not at all.What it does mean is that weight gain is a biological phenomenon first and foremost. Restrictive diets and extreme exercise programs rarely work long-term because they don't change the underlying biology.Since Stunkard's time, scientists have identified over 500 genes linked to obesity. These genes influence metabolism, appetite, and fat storage. They help explain why two people can eat the same meal, do the same workout, and see completely different results on the scale.But here's where it gets interesting: while genes set the foundation, the environment builds the house.Think about what's changed since the 1980s:More women entered the workforce, leading to less cooking at homeIndustrialized food production created cheap, highly processed, calorie-dense foodsAir conditioning made it easier to stay indoorsTechnology gave us unlimited screen timeJobs became sedentaryWork hours became longer, leaving less time for movement and real social connectionAll of these factors created a world where obesity became more common — and it happened too fast to be explained by genetics alone.Genetics loads the gun, but the environment pulls the trigger.And here's the big takeaway: obesity isn't simply a matter of willpower. It's a complex interaction between our genetic blueprint and the modern environment we live in. That's why solutions that focus only on diet or exercise often fail — and why new approaches, from medications to structural changes in society, are essential.Understanding this isn't about giving up. It's about shifting blame off individuals and recognizing that biology and society both play massive roles. When we accept that, we can start building better, more compassionate solutions.If you've ever struggled with weight, I hope this helps you see: it is not your fault.Next time, we'll explore other contributors to the pathogenesis of obesity.🌐 Learn more at weightandmetabolism.com

Let's talk about something that doesn't get addressed enough: the stigma, bias, and discrimination that people with obesity face every single day.Obesity stigma exists because of oversimplification, cultural beauty standards, medical bias, harmful language, and — yes — legal discrimination. In many places, it's still legal to deny someone a job, charge higher insurance premiums, or refuse accommodations based on their weight.In this episode, I break down why stigma exists and the real harm it causes:Oversimplification: The "just eat less, move more" narrative ignores genetics, hormones, trauma, environment, and mental healthBeauty standards: Society still promotes thinness as the ideal, and social media amplifies harmful comparisonsMedical bias: People with obesity are more likely to be dismissed in healthcare settings, leading them to avoid care altogetherLanguage and humor: Fat jokes are still socially acceptable, and medical terms are weaponized as insultsLegal discrimination: Weight-based discrimination is still legal in many places — this isn't just social, it's structuralBut we can do better. I share practical steps we can all take to challenge stigma:Use respectful, person-first language ("person with obesity" vs. "obese person")Avoid making assumptions about someone's health or habits based on their sizePromote body diversity in media, schools, and clinicsFocus on behaviors and wellbeing, not just the number on the scaleLead with compassion and empathy, not judgmentIf you want to learn more about what I'm doing to fight stigma and advocate for change in healthcare and our communities, visit my website.🌐 Learn more at weightandmetabolism.com

Before we dive into all the science, protocols, and practical tools — let me tell you why I'm really here.In this episode, I'm pulling back the curtain on my own journey: from vanilla scones and lattes to oats and smoothies (thanks to my son for that wake-up call), from primary care physician to triple board-certified specialist in family medicine, obesity medicine, and lifestyle medicine. I share what changed when I became a mother, when I started noticing the stark difference between thriving 80-year-olds and struggling ones, and why my own battle with weight and habits led me down a path I never expected.Here's the truth: even with all my medical training and certifications, I still struggle to choose the healthier option. I still want the samosa over the nuts. And that struggle — that very human experience — is what led me to life coaching. (Yes, I was skeptical too. Very skeptical. But I was also very wrong.)This episode is about why behavior change is so hard, why knowledge alone isn't enough, and why addressing your health means looking at everything — your food, your sleep, your stress, your relationships, your environment, and the patterns you didn't even know you had.This is my work. This is my why. And I'm so glad you're here.🌐 Learn more at weightandmetabolism.com
