High protein diets may facilitate short-term weight and fat loss compared to lower protein diets, but long-term data are limited and findings are not consistent.
High protein diets can help with short-term weight loss, but the evidence is not consistent for long-term results. Focus on sustainable dietary patterns rather than just protein intake.
ModerateQualifiesMEDIUM confidence
Some evidence suggests that diets higher in protein result in an increased weight loss and fat loss as compared to diets lower in protein, but findings have not been consistent... Higher protein diets may facilitate weight loss when compared to a lower protein diet in the short term (within 6 months). But long-term data are limited.
Why this rating
Evidence is mixed and inconsistent, with limited long-term data.

- High protein diets increase dietary thermogenesis (energy expenditure) compared to lower protein diets, with protein exerting a thermic effect of 20-35% of energy consumed versus 5-15% for carbohydrates.Good
- High protein meals increase subjective satiety and reduce subsequent energy intake compared to lower protein meals, particularly in the short term.Good
