30 Seconds SummaryMetabolic damage: a scientific review
- The concept of metabolic damage suggests that prolonged calorie deficits can permanently slow metabolism, leading to quick weight regain post-diet (yo-yo effect).
- No scientific studies have conclusively proven the existence of metabolic damage; the idea remains largely unverified in academic research.
- Recent research by the Bayesian team, published in the Medical Research Archives, finds no evidence of permanent metabolic damage, even in extreme cases like starved individuals or competitive bodybuilders.
- Studies show human metabolism is influenced by body composition; more lean mass increases metabolism whereas fat mass has less impact but relates to adaptive thermogenesis.
- Increased food intake reliably boosts energy expenditure, emphasizing the dynamic nature of human metabolism.
- Overall, metabolic damage appears to be a myth; human metabolism is adaptive and resilient, not permanently impaired by low calorie intake.
