Protein usually takes longer to digest, which is why consuming more protein in a diet can help curb hunger and suppress appetite. One can always choose to replace extra carbohydrates or fats with proteins, as this will reduce the hunger hormone and stimulate the metabolism. Protein helps to feel full for longer and reduces appetite. With an increase in protein in calorie deficit, one can also increase muscle mass and strength, which is difficult in most calorie deficit diets.
Apart from this, protein has been proven to be beneficial for bones and lowering blood pressure.
Some high-protein foods that can be included in the diet include egg whites, lean meats, fish, beans, peas, tofu, kidney beans, and quinoa.
