Amy - try not to feel bummed hun. You're doing an awesome job. I don't think your stomach should be grumbling from hunger though. I agree with blackduckies about your body going into starvation mode if you don't eat enough and often, it will hold on to all the fat and water for energy. Try spreading your meals out to 5 a day - still have your 3 main ones and add a couple of snacks in the morning and arvo, like some fruit, handful of nuts, yoghurt, piece of cheese, carrot sticks dipped in some low fat cottage cheese, etc, etc
