Most people that throw huge kcal numbers around like 10,000 per day, are the same people that say they're doing weights to 'tone up some fat', absolutely clueless about even the basics.
I wouldn't be surprised if Phelps ate 5-6k if his training days involved maybe 3 hours swimming total
I dont give a fuck who they are, Coach says someone was eating 2700 cals and he bumped them up to 5-7000
I call bullshit, he may have told them to eat that much but they didnt, I dont give a fuck how much they were exercising you cant eat that much food consistently at that bodyweight (145lbs)
To eat that much food would mean you couldn't even exercise, cardio after stuffing down food, garbage.
You cant just double someones food intake and expect them to be able to eat it every day.
The guys eating 2700 cals was an Olympic athlete, Im pretty sure he was eating as much as he could and knew a little bit about nutrition, for him then to just double his food intake whilst maintaining the same training routine is ludicrous.
