What if the scale isn't moving, but your health is dramatically improving?

If you've ever felt discouraged because the number on the scale won't budge—even on a GLP-1 medication—this episode will change how you think about these drugs. Dr. Cooper breaks down the research showing that the biggest benefits have nothing to do with weight loss. It's all about metabolic health.

This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor answer listener mailbag questions from California, the UK, France, Washington, Wyoming, and beyond. 

The team breaks down why Dr. Cooper does not recommend calorie tracking (and when limited tracking can make sense), how to build confidence in eating without data, and why “mechanical eating” sometimes needs medical customization—especially for people with slow gut transit or gastroparesis-like symptoms.  info_outline Mailbag: GLP-1 Weight Regain, Meals vs Snacks, and Why Some People Don’t Respond show art Mailbag: GLP-1 Weight Regain, Meals vs Snacks, and Why Some People Don’t Respond

his week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor answer listener mailbag questions that get to the heart of metabolic health. The team explains the real difference between meals and snacks, discusses whether GLP-1 medications can be appropriate for children in complex cases, explores why some people appear to be “non-responders” to Wegovy, and breaks down why alarming headlines about rapid weight regain miss the bigger metabolic picture. They also explain how to set

This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor break down two GLP-1 studies that challenge a major media myth: GLP-1 medications don’t drive weight loss just because people eat less. Instead, drugs like tirzepatide and semaglutide create direct metabolic shifts—including increased fat oxidation and improved fuel partitioning—regardless of appetite.

The team also explores mechanical eating, the psychological impact of “diet food,” and Andrea’s 13-yea

This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor tackle a wide-ranging mailbag episode with listener questions from the U.S., UK, and Europe. Topics include unexpected weight regain on GLP-1s, post-meal sleepiness and hypoglycemia, metabolic dysfunction despite normal labs, GLP-1 dosing strategies, and why these medications are about metabolism, not appetite suppression.

Dr. Emily Cooper, Mark Wright, and Andrea Taylor talk with Maria from Buffalo, a longtime listener who shares her lifelong journey with obesity, psoriatic arthritis, and binge eating—and how finally understanding the science of metabolism gave her hope. Maria describes early childhood weight gain, joint damage, and years of restrictive dieting and food shame, then explains how GLP‑1 therapy (Zepbound) plus mechanical eating helped her lose about 50 pounds while eating more food, more often, and with more joy. 

Dr. Cooper breaks down the underlying biology—leptin, weight set point, the melanocortin pathway, and the impact of pain, sleep, and chronic inflammation on hunger hormones—and reframes obesity as a symptom of deeper metabolic problems, not a character flaw. This episode doubles as a practical, emotionally honest guide for patients trying to navigate a traditional health‑care system without a dedicated metabolic specialist.

Key Questions Answered

  • How can rapid childhood weight gain, autoimmune disease, and early joint damage signal serious metabolic dysfunction rather than “too much food” or “not enough exercise”?

  • What is leptin, what does “too low for your size” mean, and how does that affect hunger, weight set point, and weight loss?

  • What is monogenic obesity testing, who might qualify for free genetic screening, and how can results inform (but not necessarily change) treatment?

  • How do GLP‑1 medications like Zepbound work with mechanical eating so someone can lose weight while eating more regularly and with more variety?

  • Which labs (fasting glucose, insulin, leptin, etc.) help uncover hidden metabolic issues, and when is a mixed‑meal test more useful than a simple fasting snapshot?

  • When should brain‑active medications (such as bupropion/naltrexone combinations) be considered, and what trade‑offs and side effects matter?

  • How can patients respectfully push for tests, challenge old “eat less, move more” advice, and set boundaries around weigh‑ins and stigmatizing language?

Key Takeaways

  • It’s not your fault: Rapid childhood weight gain and early‑onset obesity often reflect serious metabolic biology, including rare gene variants, growth phases, and hormone signaling—not gluttony or laziness.

  • Obesity is a symptom: Excess weight is better understood as a side effect of underlying metabolic fires (leptin issues, insulin resistance, brain signaling problems) that need proper diagnosis and treatment.

  • Leptin really matters: Low leptin for your size can act as a biological brake on weight loss, and chronic dieting, under‑fueling, over‑exercise, and some high‑dose supplements can suppress it further.

  • GLP‑1s plus mechanical eating: Medications like Zepbound can quiet food noise and support weight loss, but scheduled, balanced eating is essential to avoid under‑fueling, protect muscle, and support hormones.

  • Pain and sleep are metabolic: Chronic pain and poor sleep increase hunger hormones like ghrelin and disrupt repair processes, worsening metabolic dysfunction unless directly addressed.

  • Script your visits: Bring a printed list of diagnoses, medications, and questions; use patient portals to request specific tests; and practice simple boundary phrases around weighing and diet talk.

Notable Quote
“This isn’t all just caused by diets and things like that. There was an original metabolic problem. It was amplified because of the food restriction and the psychology around it, but you are a product of cumulative insults to your system—not a moral failure.” — Dr. Emily Cooper
