In adults with type 2 diabetes, eating a diet lower in carbohydrates and higher in protein is associated with higher reported feelings of fullness, increasing subjective satiety by 18% and peak satiety by 10%, even when body weight and total calorie intake remain unchanged.

Eating more protein makes you feel fuller for longer, so you’re less likely to snack or eat too much later.

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.

Just eating more protein doesn’t make you less hungry — but if you take out carbs and add fat instead, you feel much less hungry.

In adults with type 2 diabetes, eating a diet with less carbohydrate and more protein for six weeks leads to lower blood glucose levels after meals and throughout the day, even without losing weight.

Eating more protein makes you feel fuller for longer, which can help you eat less overall and avoid gaining weight.
