Episode notes
Metabolic adaptation is an adjustment
- Metabolic adaptation is the body's way to adjust calorie burning in response to calorie deficit or surplus, not damage or breakdown.
- Even extreme starvation causes only about a 10-20% slowdown in metabolism, disproving the idea of a 'broken metabolism.'
Starvation study illustrates metabolic flex
- The 1940s Minnesota Starvation Experiment starved men for six months under military conditions.
- Their resting metabolic rates dropped about 20%, rebounding to only 10% lower after refeeding, showing metabolism flexes but does not break.
Non-exercise activity drops sharply
- Metabolic adaptation changes resting metabolic rate slightly but reduces non-exercise activity (NEAT) dramatically.
- NEAT drops 350-500 calories daily during calorie restriction, greatly affecting total calorie burn and weight loss progress.
