I know someone who went on the Lighter Life diet and she lost seven stone in as many months. We saw her at a reception and she looked slim but sad because she could only sip water.
Eight months later I saw her at Christmas and every bit of that weight she had lost was back on her body. But at least she was happilly enjoying herself.
The really sad thing is that to gain all that weight back she'll have been eatinmg way more healthily than she was before doing LL, but when you go from taking in 500 calories a day to a 1000 you'll end up gaining
