Yeah, it does sound like it's difficult to lose weight once you get fat, so you are probably screwed now, I'm sorry. Some people just don't win the genetic lottery. People didn't used to be this fat, but they didn't gain the weight in the first place, it's not like it has suddenly become harder to lose weight. I suspect it's much easier to keep the weight off in the first place, and that's what I plan to do.
I check my weight fairly frequently, not that it has been out of the same 5 pound range for the last 3 years since I lost 5 pounds (not something I was trying to do) while traveling/living in South America for a 6 months. I think that may have come from climbing mountains. Not that you probably have time or the physical conditions to climb mountains, but if you do go up to fairly high altitude, maybe 12 thousand feet or higher, you will lose your appetite while you are there. When I was climbing mountains, I ate maybe 500-1000 calories in a day, and that was somewhat forced. Parents should monitor their children's weight too, it's no good letting a child get fat before they can take responsibility for themselves.
If you are always hungry when you diet anyway, you could try fasting for a week or 2, I've heard (though I've never done it myself for more than a day) that hunger goes away after 3-4 days as long as you aren't eating anything, though it comes back as soon as you do eat something.
