The meals are usually smaller and higher in protein to aid the body’s digestion and avoid the storage of excess energy drawn from food. Smaller meals are broken down quicker and allow the body to use the protein to repair and fuel itself more efficiently. Diet timing 13

This is because protein-rich diets are often low in carbohydrates so the body loses water it would normally get from carbohydrates, meaning the person loses weight.
