Similar Assertions

When lean men eat meals with more fat or protein instead of lots of carbs, they feel less hungry, fuller longer, and end up eating less food later.

86%

Obese men feel less hungry after eating high-protein meals and eat less afterward when they eat meals with more protein, no matter if it's high-protein or just enough protein.

83%

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

82%

Eating protein makes your body burn more calories after eating than eating the same amount of carbs or fat, no matter if you're lean or obese.

77%

Fat doesn’t make obese men feel as full or eat less as it does in lean men, meaning their bodies respond differently to fatty foods.
