Because as HAES teach, being fat don't cause any health problems whatsoever, so how they could connect the two things? On the contrary, knee cundishuns make it impossible to exercise and therefore losing weight, since calorie counting is a lie... no wait, I forgot many fats do totally exercise A LOT and can outrun any of you shitlords any time! It's just juhnetiks deciding your natural fat shape... (/s)
