Protein and fullness
Higher-protein snacks raised fullness ratings in controlled studies
- studies pooled in the meta-analysis
- 5
- studies in a second, directional analysis
- 28
- fullness tracked after eating, in healthy adults
- 2 to 4 hr
Across the pooled studies, higher-protein preloads raised fullness ratings more than lower-protein ones (pooled effect 2,436 mm·min over 240 minutes, 95% CI 1,375 to 3,496).1
What this does and doesn't mean
It shows that protein preloads raised how full people said they felt, under tightly defined lab conditions. It doesn’t show that Steady Bar, or any snack, changes how much you eat over a day, and the authors caution against reading it that way.1
