100 Calorie Protein Snacks

Increasing your protein intake while trying to lose weight may help you feel fuller and keep your blood sugar levels stable, thus reducing cravings. Losing weight also requires you to watch your calorie and fat intake. Choose protein-rich snacks to help ebb your hunger levels, but limit them to not exceed 100 calories so you can eat them alone between meals or pair them with a healthy carbohydrate, such as fruits, vegetables or whole grains, to make a balanced snack.
