Tough love time....
Having the attittude of "I can eat whatever I want once the weight comes off" is not good, as others have mentioned. Basically, that means you are only willing to keep healthier habits until you have lost weight, and you intend to go back to eating the same way that made you overweight to begin with.
Sooooo not good.
So, your first step is to banish that line of thinking. Second step is to find something you can stick with,
forever. Stop thinking of it as being a temporary thing-- you will have to do it for
the rest of your life so you might as well find something you can stick with.
Calorie counting doesn't work for everyone. There are other ways of losing weight, and maintaining it that you can try. Weight Watchers, Atkins, South Beach, intuitive eating, and many more. You might need to try on a few different ways until you find the right fit for you.
As for motivation, there are things I do that have helped me. Keep in mind, I often really don't feel like working out, or I really really want to dive into that fluffy birthday cake someone brought at work. But, I'd much rather grit my teeth and drag myself through a work-out, or away from that cake, than be fat.
Anyway....my motivation helpers:
* I keep a picture of me at my heaviest on my refrigerator, and on the wall in the room where I work out. It's a constant visual reminder of what I'm fighting against.
* I have pictures of me at my thinnest all around my computer. I was that way once, and can be again with some work.
* I have a sign on my refrigerator door that says "It's not in here." That's for those times I may be tempted to mindlessly rummage through the fridge looking for that elusive "something to eat" when I'm not really hungry.
* I keep charts, with little stickers for when I eat right, work-out, and record my weight loss with colored markers. I'm a visual person, so I love this. I loathe missing putting a sticker on the chart because I've skipped a work-out or binged.
* I come to 3FC often, and look through success stories, pictures, etc.
* I look into my closet and see all the plus size clothes that I now am swimming in. It never fails to bring a self-satisfied smirk to my face. (I'll get rid of them all soon)
* I used to keep a 10 lb weight on my kitchen counter, and remind myself that I had 6 of those to lose off of my body. Picking it up and feeling it's weight (so heavy!) when I wanted to go on a food rampage helped.
* Adjusting my attitude: I don't like having to work-out or eat healthy most of the time, but it's just something I have to do. Like taking out the trash, paying the bills, or cleaning the house. (I think it's photochick that I'm paraphrasing here
) Gotta do it, but I don't have to like it.
