Day 3 of diet and I am miserable :( . I have signed up with myfitnesspal, and want to lose 2 stone. I am logging calories and exercise. I have done two zumba classes, and lots of walking (15000 steps yesterday), but I walk alot anyway. Myfitnesspal has assigned me 1200 calories. Am eating healthily, no biscuits or cakes, but feeling really really down. Anyone else in same boat? I guess it will start to feel better, if/ when the weight starts coming off?!
