Proactol helps lose weight by decreasing the amount of fat you body gets. Or at least, this is what the official website claims to do. In order to find out whether this is a valid claim, a clinical test was carried out to find out whether Proactol has any effect. This Proactol review will present the result of the clinical test.The clinical reviewThe clinical study was aimed at observing whether the complex form of Opuntia ficus indica, which is the most active ingredient of Proactol, has any effect on fat binding. It was done by ten healthy volunteers(5 men and 5 women), the test was done by dividing the participants into two groups, one group receiving a placebo and the other group receiving the actual Proactol. Group 1 had to take 1.6g of Proactol for one week at each meal. The second group was required to take the placebo, which looked exactly like the Proactol capsule except that the ingredients were missing, during the same time. The participant were ignorant of what they were given, to keep out the effects of mind. While the experiment was going on,the food intake of the volunteers was similar and constant, to make sure that everyone had the same amount of fat intake. This was done in order to measure the results. The effect of Proactol was measured by checking the amount of fat in the stool of the participants after two-7day consumption periods. The resultThe quantity of fatexcreted by the group that took Proactol was measured to be 27.4% higher than the other group. Moreover, no side-effects or discomfort was reported by the volunteers. The results indicate that the ingredient of Proactol Opuntia ficus indica reduces the absorption of fat (absorption of fat from the intestine to the blood) following a heavy meal, and consequently the amount of fat excreted increases.Other than the clinical tests, Other consumers also reviewed Proactol. A receptionist Megan Jones, decided to give Proactol a try after being unsatisfied by a variety of other diet pills. She reported back that she lost 9lbs in 4 weeks and she was very glad about it. This and many other consumers review confirms that Proactol is very effective at decreasing the quantity of fat taken up by the body.What does this mean?Proactol will help you lose weight, but this is not like weight loss programs or diets. This does not require you to eat less. You can eat what you like, without fear of gaining weight. As a consequence, your body gets only the required substances from the food.
