Overall, the consensus among experts is that fat-free and skeletal muscle masses can be preserved while employing certain dietary interventions, including sticking to a workout routine, incorporating strength training and increasing protein intake. This can lead to a process known as body recomposition, where one can simultaneously lose fat and gain muscle. One strategy towards this goal is maintaining calorie neutrality while increasing activity level, and intermittent fasting has also been shown to help preserve and gain muscle mass while losing weight.
