Assuming "she" ate quite clean, had ~50% of "her" diet from protein, we guessed the majority of which was from boiled chicken breasts, *and* we further generously rounded up said breasts to an even 300 k/cals, 3,250 calories from chicken alone...well. About 11 breasts daily? On top of the greens, rice and stuff?
Yeah, okay
(Aside: I'm not suggesting this is what the chick did. For that matter, I don't know anybody who leans (haha, get it? Gets lean? Leans on? Eh, I will keep my day job...) so heavily on chicken while dieting. Most people go insane sans some variety: fish, red meat, pork, etc. I only use chicken as a means to ridicule this person's insane 6,500 calories claim.)
I don't doubt she ate more for the before and after, but I'm with the rest of you: either this person badly failed elementary math, or she's out of her fucking mind. At my heaviest, and juiced, I doubt I generally went over 4,000 calories daily -- and that was weighing a fat 250 and scarfing almost pure bullshit.
