Snacks rich in protein provides satiety and reduces appetite; thus helps to prevent unhealthy food cravings and unhealthy weight.

Male and female adolescents between the ages of 13 and 19 who were classified as either normal weight or overweight participated in the study.
Leidy said that in addition to the appetite and satiety benefits, they found that when the teens ate the high-protein snacks, they incorporated more protein throughout the day and consumed less dietary fat. Thus, adding protein snacks in the afternoon could be a good strategy for individuals who are trying to eat more protein throughout the day.
They also found that the high-protein snacks improved certain aspects of mood and cognitive function.
