Yes fasting is a good thing, this is popularly taught at least in my uni, biochem and physio profs tell us regularly and generally looking at the mountain of data that we have its evident rather regular fasting is good for you. (especially gut health). Also a cheat day is really good for helping you curb idk if you have a sugar addiction. Generally speaking its good to not eat at least 2 hours before going to bed, by the time you wake up you are fasting, ghrelin is released and when you become hungry and feel legitimate hunger, you have released ghrelin and that is pumping growth hormone like there is no tomorrow. Thanks yo this you will, suprisingly, recover faster and better and feel better. After fasting for a day or two (so eating once or twice a day, or generally just eating when hungry until you arent hungry) the false sensation of hunger generated by pleasure seeking behaviour vanishes.
However cravings for sugar etc. might persist for 2-3 days more. However fight throug it and that will also vanish. (Eating mostly meat is also a good idea, and having some carbs is necessary. You will not grow without carbs, makign growth hormone useless and you will start to degenerate rather than grow)
