Let's play fat and invent a disease, I'll start with "lipo-sporic infection" "I have cut down to 300 calories a day for 3 months and can't lose weight. Because there is Carbon Dioxide and Oxygen in the air, and Hydrogen in the water in the water I drink.  The most common form of fatty acid is COOH, those 3 elements. I have unidentified spores and a fungus in my lungs and intestines that converts these directly to cellulite."   "Now thin privileged people tell me to stop breathing and drinking water. They're trying to KE-EEL me!"
