All over the country, health shops are seeing the Madal Bal Natural Tree Syrup flying off the shelves after pop star Beyonce Knowles said she used it to shed the pounds for her latest film.
The syrup, is said to be made from the sap of maple and palm trees and costs about Ģ39.99 per liter. It is taken mixed with water, cayenne pepper and lemon juice. Dieters are supposed to drink the mixture instead of a meal at dinner time.
The diet was introduced by a Swiss health company in 1985 and although it was already popular in Europe, it came to Britain only five years ago. The only UK distributor is Pure Natural Products in Lincolnshire.
According to Cuka Clarke, who runs the business with her husband and two sons said, 'Five years ago we were selling about 500 pots a year, mainly to friends and relatives. Now we are selling about 2,000 a month. People recommend it to each other because the results are so amazing.'
She added, 'It is safe - fasting is as old as the Bible. When you are born you spend nine months on a liquid diet and when you are ill in hospital they put you on a liquid diet.'
However Azmina Govindji of the British Dietetic Association warned dieters to treat any "miracle" products with caution.
She said, "There is no evidence that detoxing is any better for you than eating a balanced, healthy diet. Fasting for that length of time, whether you are having that drink or any other drink, is likely to give you drastic weight loss anyway because it is all about the deficit of calories. It is unlikely to have enough calories or the balance of protein, carbohydrates and essential fats and other vitamins and minerals."
