OMG being hungry is in fact the hardest part of it for me. I guess I should add some tips on dancing around that!
The way to conquer eating wrong starts with what's in your house. If you still live with your parents or someone who pays for the groceries that isn't you, it becomes hard to keep the unhealthy snacks, treats and carbs out of your reach. What I did, since I am a college student fortunately able to live off campus, is I bought myself a small refrigerator for my room so that any and all cravings do not require me to look through the other food in the house.
Bread is my ultimate
weakness. Once you can't have it, you realize just how much you really have to avoid. By convincing yourself you are full though - you will begin to weaken your cravings. I tend to either eat edamame, tomatoes, almonds, or drink water between my largest meals to prevent excessive snacking. Due to my metabolism, I eat 6 times a day, breakfast - 2nd breakfast - snack - lunch - snack - dinner. If you starve yourself, you can actually put on more weight than lose weight depending on how your hormones respond to it - so be careful!
Cheat days are inevitable, just time them well and be reasonable about just how much of that chocolate, bread whatever you REALLY need.
