With the potato thing I see some of yo-yo dieting. I suspect that yo-yo dieting is what got a lot of us to an unhealthy state, or at least set the ball in motion. I think everybody is way too hung up on macro-nutrients. Potatoes aren't magic. Fat isn't magic. Yesterday I ate a grain-based bar (Journey bar, pretty unique), a persimmons, 6 huge dried figs, half a bar of chocolate, half a huge sweet potato, a carrot and a half, some nuts and a bunch of non-carby things including lots of butter, pork fat and goat fat. Was that a miracle for my body? Did I go out and preach to everybody they should eat like this? Did I sit in agony with myself because I ate fat with those sweet things or wasn't low carb? No. It was just another day like any other. Got a little sunshine, went for a hike, rested and relaxed, got enough sleep, managed not to drink too much coffee, didn't spend any money. A pretty good day.
