My plan

So this post will kind of just give everyone a general idea of what I'm planning on doing and hoping to achieve over the next few months.
I have struggled most of my adult life with being overweight. I'm not morbidly obese or anything, and I am a very active person. I just have extra weight on my body which takes away from my full potential. I have lost weight, only to keep it off temporarily then for some reason fall off the "healthy wagon" and gained it all back again. Over the past year and a half to two years I have worked so hard on losing weight, I attended the Police Academy and lost more weight. I got in pretty good shape while I was there too. I finished in July '09 and kept it off for a couple months. I got frustrated with no jobs being available and so I quit exercising and quit doing everything I was doing to stay in shape. I don't know why I did too, I wanted it really bad, but for some reason I sabotaged myself and started eating bad food, not exercising like I knew I needed to. And subsequently I gained all the weight I had fought so hard to lose.
I am sick of being overweight and as happy for them as I am, I'm sick of seeing other people that are just as big as me lose the weight and get healthy. I know that I want it just as bad as they do, I just hate that I sabotage my success for some reason. I am very motivated this time, just like I was before, but this time I am determined to lose it and keep it off for good! I want to be able to eventually do marathons maybe, or do bike marathons or something like that.
I am planning on buying a bike this weekend when I get paid and starting to ride it to work instead of driving. I work with my wonderful wife, so she will take the kids to daycare and then meet me at work in the morning. I am going to ride it down to work and then back home. I'm aiming for Mon-Thur riding the bike, but we'll see if I'm able to do that right out of the gate, or if I'll need to work up to it. It is about 14 miles one way from my house to my work, so I'll be leaving earlier, and I know it's going to suck right at first, but I know that I will lose weight fairly quickly doing that. I know bicycling is really good exercise. It builds lean muscle which is one of th easiest/quickest ways to burn fat like a furnace! :)
I also was doing a bit of research online over the weekend and I saw that Maca Root Powder is supposed to help with weight loss too. So since I work at a nutritional supplement place I just encapsulated some of it and I'm going to try it out for a month and see if it helps me any. It's also supposed to help with energy and just a general feeling of well being. I started taking it today, and I dont' know if it was a placebo effect or if it really did work, but I felt like I had SO much energy after I took the capsules.
I will be posting my weight loss per week on Facebook every Monday. I will be putting my current weight loss as my status Monday morning. I'm thinking that this will help me hold myself accountable which I know makes losing weight and sticking to it easier. I figured it would also give me a spot for some words of encouragement or criticism. I will be keeping this blog also as a way to keep a journal of what I do, and how I feel after doing it.
I am very hopeful that this is going to be my last attempt at losing weight. I am very positive that I will be successful and stick with it this time, lose the weight that I want to and be able to do all the things that I want to do but can't because I feel too self concious.
