I used to be 200lb a few years ago (Im rather tall but still, "thanks, WoW"), went on a diet and lost around 30 lb but I think I need to lose 20 more. It's just not working. I've been on 1500 calories a day diet for 2 years now, jogging 30 minutes twice a week and I walk a lot but I havent lost a any weight for more than a year now. Oh and I eat mostly protein (soy based foods since im a vegetarian, very low carbs). Calorie calculators show that I would need 1800-2000 a day even on base metabolism or with very light activity so what am I doing wrong?
