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.

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 explore the research proving GLP-1 medications are far more than "weight loss drugs." The team explains how cardiovascular outcome trials revealed unexpected heart protection, why inflammation reduction may be the real mechanism behind these benefits, and what the latest FDA approvals for kidney disease, sleep apnea, and fatty liver mean for patients. Plus: the new oral Wegovy pill, what's coming next in metabolic medicine, and why everyone should be screened for metabolic dysfunction regardless of weight.

What You'll Learn

  • Why two-thirds of cardiovascular risk reduction from GLP-1s is completely independent of weight loss

  • How these medications reduce inflammation, stabilize arterial plaque, and improve vascular function

  • The difference between MASLD and MASH—and why the name change matters

  • What the Flow Trial revealed about kidney protection (and why it was stopped early)

  • How Zepbound earned FDA approval for sleep apnea

  • Why metabolic screening should happen regardless of what the scale says

Notable Quote

"You can still become incredibly healthier even if the weight is more stubborn. So I think that's the thing, is to discuss with your doctor not 'Oh, I want to lose X amount of pounds' or 'How much weight do you think I should lose?' That is not the conversation. It's more, let's take a look at the health parameters."

— Dr. Emily Cooper
