Macro partitioning
High-protein diets (25-30% energy) improve satiety and short-term weight loss compared to standard protein diets, but long-term efficacy is comparable to other energy-restricted diets.
Increasing protein to 25-30% of your calories can help you feel fuller and lose weight faster in the first few months. This is likely because protein reduces hunger. However, for long-term success, you still need to manage your total calories, as high protein alone does not guarantee better maintenance than other diets.
An increase in dietary protein from 15% to 30% energy with a constant carbohydrate intake results in significant weight loss (Parker et al. 2002; Weigle et al. 2005)... However, a systematic review reported that the weight loss is associated with the duration of the diet and the restriction of energy intake with no association to carbohydrate restriction itself (Freedman et al. 2001; Luscombe et al. 2003).
Why this rating
Supported by multiple RCTs (Skov, Samaha, Due, Johnston, Layman) showing consistent short-term benefits.

- Very-low-energy diets (VLED) provide greater short-term weight loss than moderately energy-restricted diets, but do not yield superior long-term weight loss or maintenance.Good
- Low-carbohydrate/high-fat diets produce greater short-to-medium term weight loss than low-fat/high-carbohydrate diets, primarily due to spontaneous energy restriction rather than a unique metabolic advantage.Good
