Hey guys, I've been trying to lose about 50 pounds for a few years now. When I got my first desk job, I sky rocketed up to 225 lbs. For a 5'10" guy, that's no good. This was when I was about 21, so being young, I just cut my portions in half and went jogging, and knocked it down to my svelt 175 with no problem. Then I got married, started cooking for two, and gained it all back.

Now I'm 30 and I can't seem to shed it. I've been doing a lot of reading, and this thyroid specialist in Houston (hope the link is ok) is saying that a lot of people are unable to lose weight because as their diet worsens, it adversly affects their thyroid and that bad thyroid function can make it hard to lose weight.

Has anybody else heard this? Do you think it's a valid thing that I should have checked out? I mean, I always thought that a little diet and exercise would fix almost anything, but I cannot seem to shed this weight. I've got the strength (I lift weights and the like), and I've definitely got the flexibility (martial arts when I was younger, and I'm double jointed everywhere), but the nice thick layer of flab is keeping me from really feeling primal.

Any advice or other avenues of research would be awesome.
