They did a study a while back on the mega obeese and they had them self-report how much they ate. Most of these lying sacks of shit reported an intake of around 2000 calories. Well phase II of the study was for them to move into an institutional environment where they were actually kept to only 2000 calories a day. Ofcourse the lard asses went crazy. The funny thing is when they tested their blood on this new diet they showed all of the signs of starvation.
Fat people may have some predisposition to put on weight, BUT they can't do it without eating massive amounts of food. So next time you see your lard ass friends eating yogurt and a banana for lunch be assured that they do most of their eating in private. Once they get home they will gorge themselves on ice cream and chips.
