dont call it a diet, because then your bound to fail, think of it as changing your lifestyle, and it IS hard for the first two weeks, but your body goes into that mode and it gets easier, try saying stuff like, "im gonna eat healty for ONE week" and stick to it, and if you make it have a reward food, but dont overdue it, if you dont succeed dont be hard on yourself and just reset the goal, dont give up, it just makes it harder. hope i helped
