Never suggested it's easy. It's true if you don't get enough protein and fat (saturated fat included) bad things stars happening in your body. However if this was the case why don't they just prescribe depressed patients with protein shakes? While I'm not saying malnutrition can't happen in a modern world, it's extremely rare. But is saying no to that juicy chocolate doughnut worth better quality of life? Anyone can enjoy a pack of cigarettes a day, but don't complain how unfair the world is when you get lung cancer. Besides by getting fatter you don't burn much more calories, so not gaining fat for a 150lb person is not much harder than to 350lb of pure lard to not get any fatter, especially if we take into account fatty's lack of physical activity at such weight. If people can successful cure themselves without the use of medicine, doesn't that mean depression has no physical cause and it's just all in your head? I mean if you have a brain tumor, you can't get better without removing it first.
