A few seasons ago one contestant (man) who had won I believe gained back most if not all of his weight and they did a show where Bob went to see him. This guy had a tough time, because after all the perks and $ from the show, he'd used it all, bought a house I think and was having work and $ difficulties and had gained the weight back. This was the guy who began trying to lose again by going to a small boxing gym. Maybe you've seen that program.
He'd told Bob, "I did it before, I know how to do it again". I was surprised Bob told him NOT to do that, to just eat right and do some exercise every day. At the time I wondered why he told him not to do what he'd done before. Do you think they know what's going on? Possibly.
It is a little discouraging to realize how very hard our bodies work to get the weight back. I suppose it's nature trying to keep us from dying of starvation, something that maybe was more necessary during times when there weren't supermarkets stuffed with food.
You know, if they prove that losing weight that way is counter productive to real success, there goes the show - pffft! I'm sure anything the show's officials say is flavored by that.
Me, I'll just keep inching along.....like the turtle that didn't win the race...
