Why muscle preservation is the hidden goal of weight loss
Losing weight too fast loses muscle with it — and muscle is your metabolic engine. The high-protein diet literature is remarkably consistent: higher protein preserves fat-free mass, keeps resting energy expenditure up, and cuts weight regain by 50–64% after the loss phase. The trial results below summarize eight studies and two meta-analyses.
How to apply it
Pair any medical weight-loss program with a protein target (roughly 1.6–2.2 g/kg of body weight), resistance training, and a provider who tracks body composition — not just the scale. Get matched with a local program that measures what matters.
The short version
- Losing weight too fast loses muscle with it, and muscle is the metabolic engine that keeps resting energy expenditure up.
- Higher protein intake preserves fat-free mass, keeps resting energy expenditure up, and cuts weight regain by 50-64% after the loss phase.
- The evidence summarized in the article is eight studies and two meta-analyses on higher-protein diets and lean mass.
- The practical target is roughly 1.6-2.2 g/kg of body weight, paired with resistance training and a provider who tracks body composition rather than only the scale.
