It is important for anyone contemplating buying diet pills to understand the facts about this industry. Recently there have been two diet pills which were celebrated as being 'scientifically proven' to aid with weight loss. These products are called Xenical and Reductil.
Reductil has been taken off the market due to fears about heart problems linked to the drug. Xenical is still available on prescription, and in a over the counter version called Alli.
Studies have suggested that over the course of the year Xenical may help the patient lose up to 7kg additional to any amount lost from exercise alone. This is achieved by stopping a percentage of a persons consumed food being absorbed into the body as fat. 7Kg is not a large amount over a year, but is a small aid to those who need it.
This product, like almost every single wegith loss supplement currently for sale, will almost certainly not help you lose any weight. It has insufficent scientific study to validate its claims, and would be known about by doctors and dietary specialists like myself if it made any meaningdul contribtuion to weight loss.
My advice is to save your money and simply do ten mins more exercise per session than you currently do to lose the extra weight. Eat lots of Turkey, as it is the best form of white meat protein, and look for foods and sauces with less than 5g per 100g of fat.
