Similar Assertions

When you eat a high-protein diet with no carbs but lots of fat, you feel less hungry and more full than when you eat the same amount of protein but with some carbs.

84%

Meals with more protein tend to make people eat less at their next meal.

83%

When lean adults reduce their protein intake from 15% to 10% of their daily calories, they tend to eat about 12% more calories over four days, mostly by snacking more on savory foods, suggesting that lower protein levels may lead to increased overall food consumption.

80%

When the proportion of protein in the diet is lowered from 15% to 10% of total calories, people tend to eat more total food to maintain their protein intake, resulting in higher overall energy consumption.

76%

Even though protein makes up a small and consistent portion of most diets, it might affect how much food people eat by influencing hunger and fullness, which could contribute to or reduce obesity.
