Im not too heavy but i could loose about 30 pounds:)...I hate that i think about food all the time!~
I think its an oral fixation or like that other person said an ocd a compulsive disorder if that's the case.You have to learn to play tricks on yourself if you like things in your mouth and that leads you to think of flavors and foods.you should make home made slushies of fresh strawberries ice and like a splenda instead of sugar.and chew gum eat ice
get out of the house a lot to be away from the kitchen more and avoid commercials best to avoid most TV unless you can control what you watch with tivo commercials send a lot of signals to people about food
fast foods love to make millions on people at any cost even if the foods mcdonalds clog peoples arteries and kill them they actually call the obese people who frequent their "restaurants" heavy users like drug addicts.
My point in this is that since we are all young we have been seeing commercials and have had these same fast foods in our lives so many of them in all the main streets this is why the more you cook at home using fresh veggies and less fried stuff life with food will be a struggle.
drink tea and lots of water and make yourself walk more. walk away from the desire and think more positive about yourself your young and your smart cause at least your aware enough to know to reach out and ask for help.
Keep your head up and stand tall.you can fight those urges I've lost 109 pounds ..and Im always going to have to fight my urges its not easy but its possible. PEACE and love Misty~
