And that’s it. In a nutshell.

How does Orlistat work? Is it a fat binder?

Fortunately, you don’t need a degree in biochemistry to understand how Orlistat works. It’s pretty straightforward. Let’s break it down.

In the stomach and small intestine, you’ll find enzymes (something that causes a particular biochemical reaction to happen – a catalyst). One such enzyme is called lipase. One of its jobs is to take the fat found in food and help store it as energy. Think of it like a fat miner.

Orlistat works by preventing the lipase enzyme from fulfilling this job. This means certain fats don’t get stored, but are instead excreted when you go to the toilet (well, it has to go somewhere).

Orlistat can be described as a fat binder, so can the branded version Alli and alternative treatments like Xenical. Fat binders are not the same as fat burners. There is no evidence to support the argument that fat burner supplements work. Whereas fat binders like Orlistat have been proven to be effective weight loss treatments when taken as part of a plan that includes diet and exercise.

Is Orlistat safe and who can take it?

Yes, Orlistat is a safe weight loss treatment approved for use in the UK. You need to be classed as obese to use it. This means having a body mass index (BMI) of 30 or above.

You may be able to take Orlistat if you have a BMI of 28 or above, and you also have a health condition that would benefit from weight loss.

BMI is a relatively simple formula used to calculate a person’s weight. It divides an individual’s weight in kilograms by their height in metres squared. A healthy BMI for an adult is anywhere between 18.5 to 24.9.

  • Below 18.5 – underweight. 
  • Between 18.5 to 24.9 – healthy weight. 
  • Between 25 and 29.9 – overweight. 
  • Between 30 and 39.9 – obese.

It should be noted that body mass index is not a perfect measure of an individual’s weight. For example, its ranges can change slightly for people with particular ethnicities because they may be more at risk from having a lower BMI. Therefore, Orlistat can be prescribed ‘off-label’ for some people whose BMI is below 30 (or 28 with an underlying health condition).

When buying slimming pills online, it’s important to do so safely. That means only seeking a prescription from those who are registered to provide one, and for medications that are approved by the MHRA.

What you need to know about Orlistat

Is Orlistat effective?

Most studies agree that Orlistat is a safe and effective weight loss treatment if taken as part of a plan that includes dieting and regular exercise.

One particular study found that ‘compared to [a] placebo, Orlistat caused significant reduction in weight.’ They conclude: ‘Orlistat is an effective and well-tolerated anti-obesity drug, which can be employed as an adjunct to therapeutic lifestyle changes to achieve and maintain optimal weight.’

Other studies suggest that Orlistat, as part of a weight loss plan, can help patients lose up to 10% of their body fat in up to six months.

Can you get Orlistat over-the-counter?

How to take Orlistat

Orlistat is taken three times a day with a meal. This can happen just before, during or up to an hour after you eat. Swallow each weight loss capsule whole, with water.

If you skip a meal, skip the Orlistat tablet you’d have taken alongside it. For Orlistat to work, your meal needs to contain some level of fat. If you eat something without any fat content, you can skip that particular Orlistat pill.

What is Alli?

Alli 60mg is a similar weight loss medication that contains the active ingredient orlistat. Alli tablets are available over-the-counter at certain high street pharmacies. Meaning you don’t need a prescription to get Alli weight loss capsules. You can just talk to a pharmacist.

Orlistat contains 120mg of the active ingredient, and so is double the strength of Alli. This is largely why you need a prescription to use Orlistat and not Alli.

Is Orlistat the same as Xenical?
