Similar Assertions

People who eat a high-protein breakfast may eat about 420 fewer calories later in the day than those who skip breakfast, mostly because they eat less carbs and fat.

When people eating a high-protein diet skip their planned meal and choose something with less protein, they tend to eat about 260 more calories that day.

83%

When people eat a meal with less protein than usual, they tend to eat more total calories that day — and this pattern holds up even when accounting for other factors.
