Why GLP-1 Medications Work Even When the Scale Doesn't Move
Fat Science
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.

Mailbag: Food Tracking, Mechanical Eating Troubleshooting, COVID & Metabolism, and Metformin + GLP-1 Synergy
Fat Science
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
Fat Science
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

What the Headlines Get Wrong About GLP-1 Drugs and Metabolism
Fat Science
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

Childhood Obesity, Eating Disorders & GLP-1s: Why It’s Not Your Fault
Fat Science
This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor talk with pediatric eating disorder specialist Dr. Julie O’Toole (Kartini Clinic) and pediatric obesity expert Dr. Evan Nadler about what childhood obesity really is: a biologic, metabolic disease—not a willpower problem and not a failure of parenting.
They explore how excess weight, constant hunger, and disordered eating in kids are often signs of underlying metabolic dysfunction and genetics—and why the old

I’m Working Out—So Why Am I Getting Fatter?
Fat Science
This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor talk with exercise physiologist Russell Cunningham and patient Becca Wert about a counterintuitive reality: for some people, exercise can actually slow metabolism, stall weight loss, and trigger weight gain—especially when the brain senses a threat to energy availability.
Dr. Cooper explains how overtraining, under-fueling, and even thinking about workouts can activate famine signals in the brain and shut down

A Patient’s Guide to Taking Back Your Health
Fat Science
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
info_outlineJoin Dr. Emily Cooper, Andrea Taylor, and Mark Wright on Fat Science as they dive into the power of strength training—not just for elite athletes, but for everyday health and longevity.
This week’s guests bring unique perspectives: Faith Ireland, retired Washington State Supreme Court Justice and 82-year-old world-record-holding powerlifter, and Russell Cunningham, MA, CRC, exercise physiologist who specializes in rehabilitation, human performance, and the science of aging strong.
Faith shares her inspirational journey from recovering after a car accident to competing internationally with 15 world records. Russell explains the hard science behind why muscle strength and power are linked to bone density, fall prevention, metabolism, and even brain health. Dr. Cooper adds the medical lens, showing why strength training is essential for long-term vitality.
Key Takeaways:
- Strength training preserves lean mass, protects bone health, and improves functionality at any age.
- Research shows if you can’t leg press at least 50% of your body weight, your fall risk skyrockets; strength training dramatically reduces that risk—even into your 90s.
- Power, not just strength, is key: the ability to move quickly and explosively helps prevent falls and injuries.
- Strength training improves more than muscles—it benefits insulin resistance, metabolic health, and brain function, with emerging links to dementia prevention.
- Starting safely matters: Small steps, proper form, and gradual adaptation are essential to build a foundation and avoid injuries.
- Even 10 minutes of lifting or bodyweight movement can build health when done consistently.
Personal Stories & Practical Advice:
- Faith explains how returning to lifting after back injury and hip replacements gave her confidence and resilience, even through cancer treatments.
- Andrea admits she’s been putting off strength training and asks Faith for advice on how best to get started.
- Russell shares insights from research showing why explosive strength matters for both older adults and younger people alike.
- Dr. Cooper explains the risks of “too much too soon,” highlights foundational training phases, and describes how nutrition and hormonal health affect results.
- Mark gets candid about how yoga and even golfing without a cart reminded him how fitness translates into everyday life.
