You can check out the progress I made with 16 hours of fasting and three meals a day here.
I should note that gaining muscle on an intermittent fasting setup is not for everybody. For some people, it’s simply burdensome to eat the calories required for growth, in which case splitting meals in a more conventional manner is the better approach.
However, most find they get used to the meal pattern after a few days of adaptation, seen through decreased hunger during the fast and a greater appetite in the post-workout window (where the overfeeding takes place). This adaptation is mediated through the hunger hormone ghrelin, which increases/decreases according to habitual meal patterns.
