Two friends of yours, Janine and Mitchell, join you at lunch. During your conversation, Janine comments on Mitchell’s choice of food: a small bowl of cottage cheese, a chicken salad with vinegar and oil dressing, and a glass of ice water.

“Well, yeah,” Mitchell says, “that’s if you only eat lean protein and nothing else. But this diet lets you have fat, and you burn that for energy so you don’t get problems like the mountain men had. See,” Mitchell goes on, before Janine can interrupt him, “the thing is,
