Weight loss Pill



Alli - first FDA approved weight loss supplement

A weight loss pill called "Xenical", containing Orlistat as a main ingredient, was first approved at 1999 as a prescription drug to treat severe obesity. The main ingredient, Orlistat, is a lipase inhibitor that works to prevent fat absorption into your body.

Recently FDA has approved a reduced- strength 60mg over-the-counter version of

Orlistat called "Alli". Alli is produced by "Glaxo-Smith Kline" and is aimed to be both: a weight loss drug and a weight loss treatment plan with support.



Fat blockers and fat binders

Although, both wight loss products, Alli and Proactol are somewhat new to the weight loss market, they already are well established and very popular weight loss products.

These products work in a different ways in your body -- Proactol is a fat binder, whereas Alli is fat blocker.

Fat blocking process -- the main disadvantage is, it usually causes embarrassing anal leakage when you least expect it(!).

On the contrary with Proactol fat binder you will never experience these nasty effects. Since Proactol binds to the fat and turns it into a thick, viscous matter it doesn't cause anal leakage!

Keep in mind, these two categories of  products, fat blockers (Alli) and fat binders (Proactol), work in a different way than other diet pills available on the market.

When you take Alli or Proactol, you can rest assured that they are safe for you.

These diet pills do not come with serious side effects like some other weight loss pills: jittery effects, sleeplessness, racing heart, high blood pressure etc...

However, yet, there are certain differences between Alli and Proactol.

Alli - Synthetic Fat Blocker

First of all, it has to be mentioned that Alli is a drug and it is not a natural weight loss pill. The Main ingredient of Alli, Orlistat, is a chemical that is also used in another prescription weight loss pill called Xenical. The content of Orlistat in Alli actually is only a half then in Xenical - That's only 60mg of Orlistat content in each peal of Alli - means 2 times smaller dosage, than in Xenical. Thus become Alli a non-prescription weight loss product, but keep in mind that Alli has the same side effects like Xenical!

Orlistat, an active ingredient of Alli, is usually only prescribed to obese people with a body mass index in excess of 30kg/m2.

Are you dangerously overweight? If not than Xenical/Alli may not be the right option for you.

Keep in mind that our readers have reported some other unpleasant side effects when they used Orlistat containing products.

Side effect like an uncontrollable anal discharges, when taking this drug can well result in embarrassing situations. Other possible side effects are:

loss of bowel control

diarrhea rectal pain

liver inflammation

oily stools


If you take a closer look, the Orlistat based products like Alli, may not be as appealing alternatives as they seem at first. They certainly can't be the shining ray of light that overweight people have been hoping for.



Proactol - Natural Fat Binder

On the other hand, Proactol is 100% natural weight loss supplement, with main ingredient called NeoPuntia, which is obtained from cactus called Opuntia ficus-indica. Compared to Alli, Proactol has No side effects at all! When you use Proactol, you actually prevent from eaten fat enter into your body and all that without the embarrassing side effects of Xenical or Alli.

With hundreds of "miracle pills" available on the market, Proactol is one of the few that lives up to its affectivity claims. Several pre-clinical trials have proven that Proactol is a safe and highly effective alternative to Orlistat based products. However, as with most weight loss supplements, the best results you can achieve with Proactol when you use it in combination with a healthy and well balanced diet along with active lifestyle.
