 This week on Fat Science, Dr. Emily Cooper, Andrea Taylor, and Mark Wright answer listener questions from around the world about metabolic health. This mailbag episode explores widely-debated topics like “starvation mode,” weight loss plateaus, the relationship between metabolism and cognitive health, cannabis and metabolism, metabolic effects of liposuction, and the latest on GLP-1 medications.Key Takeaways:Dr. Cooper dispels myths around “starvation mode,” citing research on the long-term metabolic impact of dieting and caloric restriction.Weight loss plateaus are often misunderstood—Dr. Cooper explains the natural adaptations behind them and how to assess true progress.Metabolic health plays a major role in brain function, cognitive decline, depression, and dementia prevention.Cannabis affects metabolic pathways in complex ways, with regular use potentially causing negative metabolic effects.Liposuction can trigger metabolic rebound and rapid fat regain for some patients, especially when leptin levels are low.Updates on GLP-1 meds: Liraglutide is available in generic form, but costs fluctuate. New oral and combination therapies are on the horizon.Personal Stories & Practical Advice:Andrea and Mark reflect on their own journeys with dieting, weight plateaus, and medication.Dr. Cooper shares clinical experiences with metabolic rebound after liposuction and ways to navigate pharmacologic treatments.Correction: Lilly has a lower cash pay for Medicare and Medicaid, but Novo Nordisk is not yet.References related to diet-induced metabolic adaptation, also called biological adaptation and defense of body weight. 1.
