I started a diet!

I have a fast metabolism.

I'd hate to have a fast metabolism. Constantly hungry, constant energy, constantly going to the bathroom... I'm content in my sluggishness...

I knew a guy with that hyper-active thyroid disease (Grave's disease?). It's really not as cool as it sounds. I mean, he had to consume massive amounts of food just to survive, and it's not like he's a black hole - it all had to come out the other end. So instead he drank these super-5,000-calorie-vitamin-shakes-of-doom which taste like liquid feces.

He's better now, though.

Something I didn't see mentioned is that eating more often during the day, but small meals, keeps your metabolism going and promotes proper weight loss.  In other words, don't starve yourself all day for one meal because that just encourages your body to start digesting proteins and encourages you to eat far more than you need to because you're ravenous.  Instead, eat 4-5 reasonable meals during the day (some of these can simply be a snack of your choice, like some favorite fruits).  The goal is to keep your metabolism going and your body from either getting too many calories or from slipping into starvation mode.  I believe the Michael Thurman diet works something like this, and I've heard good things from people I know who have followed it.

Yep, that's the advice my doctor gave me too .  It was a bit difficult at first because I was in the habit of eating til I was full rather then eating til I wasn't hungry, and so the smaller portions were a bit of a change... but I got used to it after a while.  I'm happy to say I lost 21 pounds, and have kept it off for months now
