Diet pills: Alli

Alli promises that for every 2lb you lose through exercise and healthy eating, Alli can help you lose 1lb more.

Alli is around £50 for 84 capsules. Take 3 a day.


Type: Fat binder
You've probably seen the adverts for the diet pill Alli. It contains orlistat which is a drug that blocks fat enzymes and carries it through your body so it's not digested.

How does it work?

The pill stops your body absorbing around a quarter of the fat from food. The makers claim Alli can help you lose around a 1lb a week.

Where can I buy them?

You can only buy Alli from pharmacists who have had training from the makers of Alli. Although you don't need a prescription, the pharmacist still has to check that it's safe for you to take the pill. You have to have a BMI over 28 and follow a sensible eating plan and get more exercise.


What are the pros? 

  • It's been widely tested so we know it works.

  • You don't need a prescription to get it.

  • You have to change your diet, so you learn to eat more healthily.


    What are the cons?

  • It's quite expensive.
  • You have to take a multi-vitamin because it can interfere with some vitamins that you get from fat.
  • It can cause bloating, wind, loose stools and even anal leakage.
  • Alli isn't suitable for people with some health conditions.

    Expert verdict

    Nutritionist, Carina Norris says: 'Even though it's now available from your chemist, I personally don't think you should take orlistat (the active ingredient in Alli) unless you're advised to by your doctor. And the side-effects (it stops your body from absorbing fat in your diet, so it goes straight through you) must be pretty unpleasant!'

I've been taking these tablets for 5 days now and have lost 4 pounds. However, I'm not sure if this is due to Alli (if at all) because I've been cuttting back on fatty food. As for the side effects, you have to be really care not overdo your fat intake, otherwise you might find you have a scary moment like me this Tuesday just gone!
