I went to an introductory meeting for the LighterLife diet last night. This was the diet plan followed by Laurence Lewellyn-Bowens wife in which she shed 5 stone in a few months. This is a specialist food diet consisting of shakes, soups, and snack bars which you buy from the company, and which including weekly meetings and 'counselling' sessions costs �66.00 per week. The foods are based on a starvation diet which years ago was exported to famine victims, the idea being there's not much calorific value but all the nutrients needed to stay healthy. A healthy diet for a woman is around 2000 calories per day - the LighterLife diet is 560 calories per day.
I decided not to join as I was very concerned about the amount of water you HAD to drink, approx 4 litres a day which I consider excessive.
As a short term crash diet this may work but does not make for a healthier long term lifestyle.
