These studies suggest that high-protein, low-fat, and low-carbohydrate snacks improve appetite control, satiety, diet quality, and body composition, and provide balanced nutrition with better glucose and insulin responses.

High-protein (HP) soy snacks have been shown to significantly improve appetite control and satiety compared to high-fat (HF) snacks. In a study involving adolescents, HP snacks delayed eating initiation and reduced appetite more effectively than HF snacks. This suggests that HP snacks can be a beneficial option for those looking to manage their hunger and reduce overall food intake.
For diabetic patients, high-protein snacks have been found to have a favorable impact on blood glucose and insulin responses. A study demonstrated that high-protein snacks led to a slower increase in postprandial blood glucose levels and lower insulin secretion compared to carbohydrate-rich snacks. This indicates that high-protein snacks can be a healthier alternative for managing blood sugar levels in diabetic individuals.
Research on the effects of different snack compositions on total daily energy intake found that the type of snack—whether high in protein, fat, or carbohydrates—did not significantly affect total daily food intake or energy intake in normal-weight men. This suggests that while snack composition may influence short-term appetite and satiety, it may not have a substantial impact on overall daily energy consumption.
In women with normal-weight obesity, consuming soy-enriched high-protein snacks for six months resulted in significant reductions in appetite, energy intake, waist circumference, and body fat percentage, while increasing skeletal muscle mass. This highlights the potential of high-protein snacks to improve body composition and support weight management.
A study comparing high-protein yogurt snacks to high-fat snacks like crackers and chocolate found that the yogurt snack led to greater reductions in afternoon hunger and delayed eating initiation. Additionally, the yogurt snack resulted in fewer calories consumed at dinner, suggesting that high-protein snacks can effectively control appetite and reduce subsequent food intake.
For individuals with type 2 diabetes, a low-carbohydrate, high-protein bedtime snack (such as eggs) was found to lower fasting glucose levels and improve insulin sensitivity compared to a high-carbohydrate, protein-matched snack (such as yogurt). This indicates that the macronutrient composition of bedtime snacks can play a crucial role in managing fasting glucose levels.
High-protein, high-fiber snack bars have been shown to reduce food intake and improve short-term glucose and insulin profiles compared to high-fat, high-sugar snack bars. This suggests that incorporating protein and fiber into snacks can enhance satiety and support better metabolic health.
High-protein and carbohydrate-rich snacks with no fat offer numerous benefits, including improved appetite control, better blood glucose management, and enhanced body composition. These snacks can be particularly advantageous for individuals looking to manage their weight, control hunger, and maintain stable blood sugar levels. Incorporating such snacks into the diet can be a strategic approach to achieving better overall health and well-being.
