Clinical trial is the only objective indicator that a certain diet pill or appetite suppressant is in fact effective. From scientific point of view a specific weight loss product really “works” only if it passed extensive scientific test.



There are several expressions for clinical trial: clinical test, clinical study. They all mean the same. A specific diet drug, food supplement or appetite suppressant that passed clinical trial is proven to have measurable effect on human body. Such drug actually works. If we come back to diet pills and appetite suppressant, an average person seeking for weight loss products easily comes across this statement: “diet pill that really works”. Those should be considered with healthy dosage of skepticism. One should seek for clinical trial of the product he intends to purchase.

The first conclusion one could make is, that if a diet pill or appetite suppressant has clinical trial, that product must be good. Actually it is not that easy. There are all sorts of clinical trials out there. Not each kind of trial can be trusted. But there are some basic principles one should consider when looking at clinical trial. Firstly, the medical institutions involved (at least two independent institutions) in a trial should be from countries that you can trust. USA or EU standards of conducting a clinical study are different than for example in India. Secondly, one should look at the size of the group involved in the trial. Test groups of 200 people or less are rarely considered as “scientific approach”. Thirdly, one should make sure that the clinical trial concerned, has been executed on humans. If a specific weight loss pill or appetite suppressant made a rat loose 20 grams in a day, there is no objective way to transfer those results on human body.

Regardless the fact that clinical trial makes it easy to categorize diet pills and appetite suppressants according to effectiveness, one should know that clinical trials are not compulsory for all dietary products. Only prescription drugs must have those in order to be eligible for selling in US and EU. Food nutrition supplements, among them no prescription diet pills and over the counter appetite suppressants, do not have to pass clinical trials. Regardless to that, most sophisticated “over the counter” diet products have clinical trials. Clinical trials are becoming a “must have” quality statement, which helps serious drug producers gain respect on the market.
