Anytime I've ever gained any weight back, it's becuase I have backslid and have started slipping back into my previous unhealthy habits that made me heavy in the first place. If I plan my meals, watch my calories and eat whole foods, the scale never goes above 130. If I eat a lot of dinners out and snack on double handfuls of nuts and eat dessert every day for 3 days, the scale goes up 3 lbs.
I just don't think the odds have to be so grim. Pick something you can stick with, stick with it.
The big thing these researchers are finding is that it's not all that simple, at least on a societal level. The current weight theory is that a calorie is a calorie and a body is a body - any given body that takes in too much food will gain weight, and that overweight body just needs to take in less food to lose weight. Fat people are just skinny people who ate too much, and skinny people could be fat people if they overate the same way.
On a person-by-person basis, what you say is true - eat less to lose weight, eat less to keep it off... and that works. But it's always seemed pretty unfair that some of us will have to fight every day to keep the weight off... you can never eat like an "average" person if your body wants you to be fat. And that's not just in our heads.
Someone sent me the NYT book excerpt a few weeks ago that summarizes some of this: basically showing studies that the bodies of obese people who lose weight function similar to the bodies of people who are starving - metabolism drops and the body fights vigorously to go back to its previous weight. The even more striking part was the opposite study: "Ok, so fat bodies have somehow changed by being fat, and want to stay fat.... let's take some average people and have them gain weight" - the argument being that the body somehow adjusts to being fat and wants to be there. Instead, the metabolism of the average-weight volunteers went into overdrive, burning huge amounts of calories given their body size - basically fighting to get back to their normal weights.

I've got the book sitting on my desk but haven't had time to crack it due to work, but I'm looking forward to it. It may seem kind of discouraging in some ways, but I'd rather understand the factors that influence my body as thoroughly as I can. Instead of wailing "it's not FAIR!!" and getting frustrated that my 120-pound friend can freely eat 2500-3000 calories a day without ever having to think about it, I can see the scientific proof that, no, it's really truly NOT fair, and my body is fundamentally different from hers. At which point I can choose to a) accept that I'll always be fat and choose to live that way (which is still going to be healthier than yo-yoing and crash diets and such), or b) accept that my body is going to take a considerable amount of effort to get it and keep it where I want it to be, and understand that it's going to be an uphill battle for the rest of my life. (i.e. I CAN do it, but I have to accept that it won't be "easy")
To some it may seem discouraging to see that the genetic deck is stacked against us. But, at least if you KNOW the deck is stacked, you know what you're up against - it's better to know what the odds are and face them head-on, rather than trying to fight those odds blindly and getting frustrated when it doesn't seem fair (which it isn't).
