Macro partitioning
High-protein isocaloric diets (HPD) preserve or increase muscle mass during weight loss, whereas very low-energy diets (VLED) significantly decrease muscle mass.
If you are losing weight, ensure your protein intake is high (around 1.8g per kg of body weight). This helps you keep your muscle while losing fat. Very low-calorie diets without high protein will cause you to lose muscle mass.
HPD increased muscle mass at 12 weeks (2.95%, p = 0.001), while VLED decreased it (−2.02%, p = 0.031).
Why this rating
Randomized controlled trial design with clear statistical significance (p=0.001) for the specific outcome.
