Proactol Vs Alli review: Fat Blockers compared

Fat binders  (or fat blockers) are a type of diet pills that works by eliminating some of the fat that you eat. With fat being the most calorie dense nutrient, this results in a large proportion of calories eaten at each meal being passed through the body without being absorbed.

They don't work on the central nervous system or brain, and instead work in the digestive system to prevent weight gain at the first point of entry to the body.

What are the best fat binders?

Our interest was caught by the recent press on the Fat binder Alli. It has recently been made available over the counter when previously it was a prescription drug.

Whilst this means that we can get some great deals and impressive discounts due to competition amongst retailers of Alli, it also means many more of us can experience the weight loss possible from prescription diet pills.

We decided to dig deeper, to find out if Alli was really the champion of its field. Is Alli really the best fat binder? We searched to find a fat binder that provides the same (or even better!) results than Alli whilst avoiding some of the side effects Alli can have.

We found Proactol XS, which acts in a similar way by blocking around 25% of consumed fat from being digested, but without the side effects.

Both pills are impressive in their own right. On one hand we have an extremely successful, clinically proven pill with Alli with the drawback of  the “treatment effect”.

On the other we have a product that receives amazing testimonials and has no known negative side effects.  We have created an in depth review on each product to help you to make the right choice.

We used our 4 point rating criteria to ensure we picked the highest quality and most effective choices.

Just beating Alli, mainly for its lack of known negative side effects, is Proactol XS.

In clinical tests it has been shown to block up to 28% of fat and has seen impressive weight loss results.

The best news is that Proactol XS is made from 100% natural ingredients, so no synthetic chemicals filling your body.It has a dual action approach of preventing fat absorption but also forming a solution in the stomach that makes you feel fuller for longer. This means that as well as acting as a fat blocker, it has an appetite suppressing effect.

This really is a product you can't afford to miss. Our in depth review covers exactly how Proactol works in more detail, and has some interesting testimonials from people who have tried it.

Alli's key ingredient is Orlistat,  also present in Xenical, which is proven to block up to 25% of dietary fat.

We were impressed to see not just reports of weight loss, but also reports in improving of health conditions such as diabetes, heart conditions and high blood pressure.

Hi, I'm Aileen, the owner of Diet Pill Judge. I have personally tried loads of diet pills over the years and found that only a few of them really work.
My background is in science, so I set out to find supplements that have scientific evidence behind them and which I can confidently recommend.
