Which of the following is true about high protein snacks?

High protein snacks that are low in excess fats or carbohydrates can effectively enhance satiety, which may lead to weight loss. This is due to the thermic effect of protein, which requires more energy to digest compared to fats and carbohydrates, thereby increasing the overall caloric expenditure. Additionally, protein promotes feelings of fullness, which can help control hunger and reduce overall calorie intake when included as part of a balanced diet.

The other statements do not hold true universally. For example, it's not accurate to claim that all protein snacks are beneficial regardless of their other ingredients, as some may contain unhealthy additives. Similarly, not all high protein snacks are necessarily high in calories; they can vary significantly in their macronutrient composition. Finally, while protein shakes can be a convenient source of protein, there are many other acceptable sources of protein, including whole food options like nuts, Greek yogurt, and lean meats.
