I know right, they think they metabolize fat from thin air. My obese sister in law has been desperate for a diagnosis to explain her massive weight, general poor health, fatigue, aches etc. Said she'd lost faith in modern medicine haha. One doctor finally threw her a bone and told her fibromyalgia, cue whale tears about what a relief it is to have a name for her illness.  She asked me the other day how I have a flat stomach after my pregnancies (we have same number of kids) I said exercise without missing a beat. She looked so bummed. What did she want me to say?.. "I take these magic beans every morning.."
