It's a great mystery. They always whine that they're fat because they can't afford healthier food and they're not rich enough for personal trainers and personal chefs. Yet they always seem to spend far more on food then me. Buffets several times per week, preprepaired food several times per day (most fats are too lazy to cook), all in VAST quantities. Yet strangely I'm able to eat both more frugally and healthier.
