Losing fat while gaining muscle may seem like a fitness myth, but research shows it is possible in certain situations. This process, called body recomposition, goes against the old idea that you can only build muscle by eating more calories than you burn. Is it scientifically possible to build muscle in a caloric deficit? “It is scientifically possible to build muscle while being in a caloric deficit, provided the deficit is moderate and not extreme,” says Dr Prakash. “In such cases, the body can tap into stored fat for energy while muscle protein synthesis is stimulated through resistance training and adequate nutrition.”
