Fasting can offer benefits for body composition, specifically fat loss and muscle retention, potentially exceeding those from continuous caloric restriction.

“Let's start with the evidence around fasting and the improvement of body composition. This is a very important concept when we think about GLP-1 agonists where if you are not deliberate about how you use that tool, you will indeed lose a lot of weight but you might not achieve the body composition results you want. And the same is true with fasting. So to be clear here the question is does fasting offer benefits for body composition i.e. Fat loss, muscle retention beyond what you would expect from continuous caloric restriction.”
