I have read many people say that IF can alter body composition. So like your weight is the same, but you appear smaller, or something like that.
Is it IF doing that? Even without exercise? Can someone explain the science of this idea?
I don’t think you’d see a lot of recomposition without also doing exercises like weight lifting, honestly. But assuming you are lifting weights, fasting has been shown to increase HGH production, which helps with muscle growth. There are increased benefits when you time your exercise to be right at the end of your fasting window, eating right after.
