Lame serious post

Just thought I'd warn you up front.

I have been overweight my entire life. I was born 9 lbs. and never looked back. Part of it is genetics, and part of it comes from being fed fast food as a child by my father. My mother, the uber hippie that didn't allow us to eat sugary snacks and raised us to like fruits and vegetables, tried her hardest to undo the damage he did to us, but it really was never enough. Bad habits outweigh the good habits.

So here I sit at 24 years old, miserably overweight and feeling like I'm unable to do anything about it. I have a gym membership and I'll go regularly for a week or two, and then just lose the motivation. I'll get on a kick where I'm eating extremely healthy for a week or two, but then my friends will want to go out to dinner and I'll revert right back to my old habits.

My mother told me about this doctor that has a program that can change the way you look and feel in about one month, by eliminating food allergens from your diet and then slowly reintroducing them. In that one month I would have to give up gluten, sugar, alcohol, caffeine, dairy, eggs, and a few other things. That means no bread, no cheese, no desserts, no wine, no Halloween candy, etc. Tough, of course, but it could change my life to figure out what foods I'm reacting to that are causing me to gain weight. And still, I'm dragging my heels because it would be a challenge and I wouldn't get to eat my favorite foods and go to bars with friends. For one stupid month.

Am I being completely crazy? Or am I just scared to fail again, so I don't even want to take the first step?
