Research has supported the positive effects of __________ on both satiety and thermogenesis.

1. fat

2. protein

3. carbohydrates

4. fiber

The correct answer is: protein

Protein is the correct answer because numerous studies indicate that consuming protein has significant benefits for satiety, or the feeling of fullness after eating. High-protein diets are known to reduce hunger and increase feelings of fullness, which can lead to reduced calorie intake overall. Additionally, protein has a higher thermic effect of food (TEF) compared to fats and carbohydrates. This means that the body expends more energy digesting and metabolizing protein, which can enhance thermogenesis— the process of heat production in the body. This thermogenic effect can contribute to increased energy expenditure, making protein an important macronutrient for weight management and metabolic health. Other macronutrients, such as fats and carbohydrates, do not have the same level of impact on satiety and thermogenesis as protein does. While fiber also plays a role in satiety, it does not contribute to thermogenesis in the same way that protein does. Thus, protein stands out as particularly beneficial for both creating a sense of fullness and supporting metabolic processes.
