One of my training partners used to get up every three hours and make a tuna milkshake and drink it down before going back to bed. He eventually started smelling like a fish and his wife had to move to the second bedroom just so she could get a good night's sleep.
It didn't take him too long to change that diet, but it did work for him and he good shreaded to the max.
Also, there used to be a bodybuilder in the early days of Venice Beach who ate nothing but tuna fish that he dried out by twisting it in a nylon stocking until it was thoroughly dry of all the oils and moisture. I reminded me of sawdust with a distinctive odor.
I can't remember if he ate anything else but I kind of recall honey and bee pollen which was pretty popular back then.
