10 pounds in 2 weeks? That would be almost impossible to gai in actual body fat. Most likely it was a largely fluid retention.

I've been a fat guy all of my life. From adolescents forward, I was between 300 to 250 lbs.

My only longer term weightloss success has been when I finally got proper treatment for my bipolar. Having the stability of my mood has given me the ability to make better choices both eating and excersize.

I think the key to success with the exercise is to almost be neurotic about it. I treat it like a medication, so I have to do it. The alarm clock goes off in the morning..I eat breakfast...I get ready and go to the gym. It's not an option, just like not taking my meds isn't an option. I know if I don't take my meds things go off the rails pretty quickly, and I take the same mentality to working out.

Once you can do that, a lot of other things just sort of fall into place. You start to feel better physically, you start to feel a little better mentally. Since you are making the effort to exercise it leads you to have stronger will power to make better eating decisions. Basically, "Is this donut worth negating everything I did in the gym this morning?"

Find little goals to motivate and challenge yourself with. For me a huge one was just being able to run a mile continuously. Once I could do that, it changed to 1.5 miles, or the time to do the mile, etc. What's crazy for me is that I now challenge myself for faster 5k and 10k times. Two years ago I couldn't jog a mile.

Anyhow, the biggest key is the exercise. If you can get that into your life it can also compensate for the times you fall of the wagon eating wise.

Sorry for the rant!
