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.

This week on Fat Science, Dr. Emily Cooper, Andrea Taylor and Mark Wright take a hard look at the buzz around microdosing metabolic medications—from what “microdosing” actually means to the risks of following trends without clinical supervision. The team unpacks widespread misunderstandings about dosing for drugs like Ozempic, Zepbound, and low-dose naltrexone (LDN), explains why social media advice can be dangerous, and highlights just how unique every person’s metabolic needs are. 


Dr. Cooper shares patient examples and lays out the science behind hormone regulation, medication resistance, and why skipping a full evaluation could backfire. We cover why glandular extracts and testosterone supplements can disrupt your body’s natural balance and why trying to “trick” your metabolism with tiny doses can sometimes do more harm than good.


Key Takeaways:

  • Microdosing means doses far below anything supplied by drug companies—it’s not the same as prescribing a lower dose within the normal range.
  • Popular trends in LA and beyond push people toward self-experimentation, often with compounded drugs or unsupervised regimens.
  • Taking metabolic drugs without a clinical need can weaken natural hormone production and create dependency—even with “natural” supplements.
  • GLP-1s, GIPs, naltrexone, and testosterone all show very different outcomes depending on your genetics, history of dieting, childhood athletics, or use of other medications.
  • More is not always better. Too high a dose can create medication resistance, while too low might “numb out” your hormone response.
  • Professional evaluation, sleep, nutrition, and self-kindness remain the first line of defense for metabolic health, rather than skipping over those and heading straight to medication.
