Protein usually takes longer to digest which is why consuming more protein in a diet can help curb hunger and suppress the appetite. One can always choose to replace extra carbs or fats with protein as it will reduce the hunger hormone and boost metabolism. Protein helps in feeling fuller for a longer period reducing the cravings. With an increase of protein in calorie deficit, one can also increase muscle mass and strength which is difficult to do in most calorie deficit diets.
Apart from this, protein is proven to be beneficial for bones and lowering the blood pressure levels.
Some protein foods that can be included in the diet are egg whites, lean meat, fish, beans, peas, tofu, kidney beans and quinoa.
