I focus my eating on these points:
Do I like eating this? Does it make me feel full?
Does it make my body feel good and give me enough energy?
Does it have any adverse effects, eg dehydration, high cholesterol, etc.?
Does it promote health through macronutrients, vitamins, etc.?
Bottom line: I eat food based on these criteria within a limit of 1500 kcal/day. I try to get 40g fat, 80g protein and 120g carbs, though I have had a few days hitting 200g carbs. Regardless, I keep my focus on eating good food (less refined and processed) and staying at 1300-1500 kcal/ day. And it's working: 14 lbs lost in 7 weeks.
I am not losing weight. I am gaining health. Since April 24, 2012:
