Adherence
High protein meals increase subjective satiety and reduce subsequent energy intake compared to lower protein meals, particularly in the short term.
Eating more protein at your meals can help you feel fuller for longer and naturally eat less later in the day. This is one of the most effective ways to manage hunger without strict calorie counting.
GoodSupportsHIGH confidence
Of 14 studies that compared high protein to at least one other macronutrient, 11 found that the protein preload significantly increased subjective ratings of satiety... Of 15 studies identified, 8 showed a significant decrease in energy intake after the higher protein preload.
Why this rating
Strong consistency across 11/14 satiety studies and 8/15 subsequent intake studies, despite heterogeneity.

More from this paper
- 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 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.Moderate
