Why Diets Fail: The Science of Set Point & Metabolic Adaptation

Dr. Alessia Roehnelt | Endocrinologist Season 1 Episode 15

Why do most diets fail? It’s not a lack of willpower. It’s biology. In this episode of The Wellness Protocol, Dr. Alessia Roehnelt, double board-certified endocrinologist, breaks down the science of why restrictive diets backfire, how metabolic adaptation slows weight loss, and why set point theory makes it so hard to keep weight off long-term.

You’ll learn:

  • How the body defends its weight through hormones, hunger, and metabolism
  • The truth about “starvation mode” and the “Biggest Loser” effect
  • Why cutting calories too aggressively sets you up for rebound weight gain
  • Sustainable, evidence-based strategies for weight loss that actually lasts
  • How sleep, stress, protein, and strength training play critical roles in metabolism

If you’ve ever felt frustrated by diets that stop working, or blamed yourself for regaining weight, this episode will give you the clarity and tools to finally work with your body instead of against it.
