I will never be that weight again

Tonight on the Biggest Loser, they had to climb up a mountain while wearing weights of the weight they had lost.  (If they lost 50 pounds, they had to put 50 pounds on their back.)  And they were all saying, "I will never go back to this weight."

But the reality is more than 80 percent of people who have lost weight regain all of it, or more, after two years.  Researchers at UCLA analyzed 31 long-term diet studies and found that about 2/3s of dieters regained more weight within four or five years than they initially lost.

So Depressing!

I should get a weighted vest and force myself to walk once a week carrying my starting weight.  Would this help me remember how awful it is to be at that weight?  Would it help me keep the weight off?
