Energy balance

Moderate weight loss (5-15%) provides significant health benefits with minimal metabolic adaptation (small RMR deficit), making it a more sustainable and effective long-term strategy than dramatic weight loss for improving metabolic health.

Aim for a 5-15% reduction in body weight rather than extreme loss. This range provides major health benefits with minimal metabolic slowdown, making it much easier to maintain long-term. Focus on sustainable lifestyle changes rather than rapid results.

GoodSupportsHIGH confidence
For persons with overweight or obesity seeking definitive improvements in their metabolic health, a weight loss of 5%, 10%, or 15% is recommended... they might see only a small deficit in RMR of 50 to 150 kcal/day.
