If your hungry all the time and you casn't eat a lot that could be considered anorexia, which isn't cool at all and extremely dangerous! For your legs try excercizes where you lay on your side and lift your leg up 25-30 times. and do crunches opp. leg to opp. knee! Eat what you;d like but try lowering the junk food and since your eating so much healthy food, have those for snacks between your big meals like breakfast, lunch and dinner.
