You want your diet pills to work for you and reduce your weight or the fat you carry.

That’s great but if all diet pills worked for everyone all the time why would we even have an obesity crisis? Good question! Which pills work? Which don’t? You know that the best thing for you to do is eat well and exercise regularly but is there any ‘cheat’, ‘shortcut’ or aid that can help you lose that belly any faster?

I must stress that this site is not a source of medical advice and shouldn’t be considered as such. The first thing you need to do if considering help with weight loss is consult your doctor or another medical professional and take their advice.

That being said let’s take a look at the whole issue of weight loss pills and see whether there are actually any out there that we can find that do work. We’ll also have a look at the different ways they work (there is also a post here about how diet pills work)

There is a comprehensive review of one group of diet pills using orlistat at the NHS website here.

Alli (which is a registered trade mark of a drug made by GlaxoSmithKlein) is one of the slimming aids commercially available and it uses orlistat. The same chemical is used in Xenical by Roche.

You should note that Alli is only available for adults with a BMI of over 28 and you will need to collect it from a pharmacy if in the UK. In the US you can buy this direct from AmazonĀ (click here)
or with the link below. If you don’t know what your BMI is you can check on the BMI calculator on this site.

There is another drug on the NHS site called Appesat which you can get from Amazon here.

Appesat works by basically swelling up in your stomach and fooling your body into thinking you are fuller. This is designed to be used by people who feel they over eat. There are warnings that you should not use this if your body mass index (BMI) is lower than 18.5 which is generally considered normal.

Another weight reduction drug that used to be prescribed Reductil (Sibutramine). This also worked by making you feel fuller, it boosted something called seratonin, a ‘feel good’ chemical. My understanding is that sibutramine has been withdrawn from several markets. Click here. and here.

Orlistat is a prescription drug although there are lower strength variations of orlistat available over the counter. The lower strength will absorb less of the fat. I have read the difference is up to 30% fat absorption for the prescription pill and up to 25% for the over the counter pill.

Other types of pills include the following:

  • ‘Thermogenic’ pills which aim to work by raising the body’s temperature so you use more energy (read calories) and lose weight better. Sometimes these are sold as aids to workouts and exercise.
  • Raspberry ketones are alleged by some to help prevent fat absorption into your body weight
  • Green coffee bean extract is supposed to slow the release of glucose into the body and so help prevent weight gain
