What should I do about my eating habits?

I know exactly how you feel... but my advice to you would to be at first learn to get comfortable in your own skin. Everyone has something they don't like about themselves but try to get that list down something small and not big like your weight! Start not liking your habits like throwing the food up. Start to control yourself and say to yourself, I just ate a whole bag of popcorn by myself but I'm not gonna throw it up. Learn portion control. People take out plates and bowls and they think the dishes themselves are the tell tale sign of how much to eat so they pile it on the plate or fill the bowl up. Eating like how you have been isn't all that half bad. They recommend eating 4-6 small meals a day... like for example, an apple with PB or a toasted turkey sand which on wheat bread. Doing this will increase your metabolism. Eat the small meals but limit yourself when you splurge. It's alright to eat 4 oz's of ice cream every now and again just don't sit down with the whole tub. And one last thing, never never eat in front of the television with processed foods (i.e- chips, crackers, oreo's, chocolate chip cookies). Take out say four oreo's and eat them. I find that when you are in front of the television you get in that trance and realize you've eaten so much. You just know what your eating is good and your gonna keep eating it. And remember everything in moderation. Look up some food high in fiber and protein to help with your metabolism or if you feel lethargic (which carbs make me feel that way) get a daily vitamin with the B's in it. All the B's are great for increasing your metabolism. Hope this helps!!!!
