Wouldn't you love to do this? I would love a holiday in a gorgeous location where they pamper you with massages and facials while you have professional chefs prepare specialty dishes that are all natural and low calorie. I wouldn't mind living at one of these places for about six months. Diet spas are severely expensive. I wish I could afford that!
I remember when I was a kid, my one cousin was very heavy. His parents sent him off to a "fat farm" and he came back after summer was over and he was slender and suntanned. He did gain it all back though.
