one friend does this and he also doesn't eat all day. great genetics on him, not the best training principles...

looks like zyzz when he eats more, looks a lot skinnyer but lean as hell when he eats less lol, like 6'3 220.

his younger brother looks good but not as good, they both take no supps, and he just recently said "you know what's been helping with my fatloss so much man!!! FISH OIL! i just take 2 caps a day!"
