Alli is a weight loss treatment with a difference; it is clinically validated and pharmacy-licenced for over-the-counter sale.

Alli has been clinically proven help those with a BMI of 28 and over, lose weight sensibly. It's active ingredient is Orlistat, the same active ingredient found in Xenical, a prescription-only weight loss treatment. Because it is a pharmacy-licensed and clinically validated weight loss treatment, Alli is unlike any other weight loss product that has previously been available in the UK.

For every 2lbs you lose from eating healthily, Alli will help you lose an extra 1lb. It works by stopping a percentage of the fat you eat from being absorbed, helping to boost your weight loss by 50%.

Alli is a weight loss programme consisting of 3 pills taken daily along side a low-fat, calorie controlled diet. 1 Alli tablet contains 60mg of the drug Orlistat which helps prevent about a quarter of the fat eaten in every meal from being absorbed by the body. Note, however, that you can't just take Alli and pig out as it stops some fat from being absorbed into the body, but not all of it. In addition, taking Alli will not prevent sugar or carbohydrates from being absorbed into the body (which is a good thing to a degree, because the body needs some sugar, carbohydrates and some fat).

The history of Alli
Alli contains the drug Orlistat and used to be marketed under the name of Xenical; a medicine available only on prescription since 1998. Alli is the over-the-counter version of Xenical and is available from UK pharmacies including Express Chemist. Alli is manufactured by GlaxoSmithKline and has been clinically tested, both for its safety and effectiveness. The launch of Alli has already been a huge success in the USA. There has been some controversy as to whether it's a good idea to take a pill to lose weight rather than change your eating habits - but we hope it can be seen that Alli is different in that it is a whole support package, and not just a quick fix. And Alli is very effective.

What makes Alli any different to other weight loss pills?

The difference between Alli and any other non-prescription treatment is that Alli has a pharmacy licence. This means that it has had to undergo rigorous clinical testing before its release, to ensure that it is both safe and effective. Alli does not make any claims that cannot be substantiated, and is not sold as a miracle cure; instead, it acts to support your weight-loss programme in a clinically proven manner.
