How much weight will i lose on this diet and how quick? and what can i do to stop pigging out on junkfood?

That's a bad diet. Too little calories can be unhealthy for you. Your body Is hungry because you eat so little. You don't need to diet to loose weight, you just need to watch your portion size and eat healthy food. Exercising and eating right will help you loose weight. Don't think abou how many calories each food has, think what is healthy an what is not, but watch your portion size. Healthy foods have less calories. So don't think omg this has this many calories, as long as you eat healthy, you'll loose weight. You also need to exercise, because muscle burns fat. Try walking, then when your ready,run. Just exer use one hour a day. You can loose weight by walking, and if you want to tone your body work on those apecific areas. You could still eat pizza, and chips, but don't eat like 4 slices of pizza and the when bag of chips. Eat a salad first then eat a slice or two of pizza, the you could go outside and walk it off. Eat healthy snacks too. Like a fruit salad, or a granola bar. Just watch your portions n eat small meals. Have a variety of healthy foods available so of you get hungry, you have healthy foods.
