:( Well, if you eat really good gourmet food ( it's usually on the healthier side), you won't want to go back to the junk. When I was small I would anything. From junk to gourmet. Loved the junk, but with the years, really junky food made me nauseous because it's so full of chemicals and crap. Now I can only eat a little.
I think you should try and make the transition slow. No way you are going to change over night.
Keep eating burgers and fries, BUT, don't order out from MacDonald. Make your own. Buy lean ground meat, put some cut onions, some bread crumbs, salt, pepper, etc. Mix it and barbecue it. Try using real cheddar instead of kraft, ;) put all the toppings you want. Ketchup, mustard, tomatoes, lettuce, bacon...
Instead of buying fries, take some extra time to cut a sweet potato or potato, (cut them thinly) sprinkle some salt, pepper and herbs, dump it in the oven. Still yummy, but less fattening.
Eat chips, but eat the ones that are more natural and just have salt. Not the ones with fake cheese etc...
Try starting out like that. Eat the same foods but not the store bought processed one with chemicals. That should help. Chemicals are really what make us gain. Our kidneys cannot handle all the purifying so they send some of the crap to our liver. SO instead of breaking fat, our liver has to get rid of chemicals. AND SNACKING AT NIGHT! That's my weakness. I can starve all day, but at night, for some odd reason I NEED TO EAT! :/ But really, just not eating after 7 (even if you eat junk all day) will help you loose weight.
Eventually move on to more healthy foods. (If you eat yummy gourmet food, those veggies won't look so boring. ;)
Also, when eating vegetables, if you eat them with yummy, spicy dips, or put lots of butter and salt on your cooked vegetables, they aren't so boring. Too much butter isn't good for you either, but I think you need to start it out slow. Slowly but surely.
BUt I have a question. I hope it's not too personal. You don't need to answer, but often people eat because they are depressed about something and find comfort in food. Is that your case? If so, then well I guess the obvious answer is to try and fix that issue. If you just love food like I do, don't worry, willpower grows. Just work on it. ;) Give yourself goals! Try small things, like I will replace that bag of chips with a bag of peanuts, or almonds.
Ouf, sorry this is a lot of blabbing and I am writting this in an awkard position over my mom who is on the phone, but I really do hope things get better! Don't worry, you'll overcome this if you really want it. Takes time sometimes. You have to find what works for you, what motivates you enough. :)
*Hugs*!... I also find chewing gum helps me not snack.
A ride a day keeps the worries away!
