Weight Loss Studies


    Dr Erling Thom, who ran some of our studies

Several controlled scientific studies have been conducted on Svetol®, the active ingredient, and also on CoffeeSLENDER®.

In these studies, the participants who used Svetol lost around twice as much weight compared to those on the same diet but not taking Svetol.

All the scientific data supporting CoffeeSLENDER has been thoroughly reviewed by Dr R.E. Lister. Dr Lister is an independent expert in Clinical Pharmacology, Trial Management and Nutrition and, amongst various Advisory roles, is Chairman of the Institute of Brain Chemistry and Human Nutrition at London Metropolitan University. He has had over 60 scientific papers published.

This is what Dr Lister had to say about CoffeeSLENDER:

 “The results from the studies on volunteers using either Svetol or CoffeeSLENDER are sufficiently convincing to warrant the conclusion that CoffeeSLENDER can be of positive benefit in aiding weight loss when used according to the maker’s instructions”.

Details of these studies as well as references to other research into the bio active substances contained in coffee are available for you to download at the bottom of this page, but in summary;

  • In a study published in the November 2007 issue of the Journal of International Medical Research, Norwegian scientists studied the effect that drinking CoffeeSLENDER regularly had on body weight. A 12 week, comparative, randomised, double blind study was carried out on 30 people, with half drinking CoffeeSLENDER regularly every day, and the rest drinking ordinary instant coffee. At the end of the study period, the participants drinking CoffeeSLENDER had lost an average of 5.4kg (11.9lbs), whereas those drinking ordinary instant coffee showed no statistically significant weight loss. Additionally, the quality of the weight loss in the CoffeeSLENDER group was excellent, with 82% of the weight reduction measured as a reduction in body fat.

  • In a study published in 2007 in the peer reviewed journal, NutraFoods, Dr. Blum and Marshall-Blum LLC (also a company that specialises in clinical trails) conducted a study using Svetol at the University of Maine Department of Food Science and Human Nutrition. In the published results, the respondents lost an average of 1.5kg (more than 3lbs) in 6 weeks without diet or exercise changes*.
  • In 2005 Dr. Erling Thom of PAREXEL (a company that specialises in managing clinical trials) conducted a trial on Svetol in Norway. The study was a randomised, placebo controlled double blind study using Svetol combined with a calorie-controlled diet over 60 days. The 30 participants using Svetol lost more than twice the amount of weight compared to those on the same diet but without Svetol. Those receiving Svetol lost an average of 5kg (11lbs). The other 20 subjects following the same diet but not taking Svetol lost an average of 2.4kg (5.2lbs).
  • A randomised placebo controlled study on 50 people over 60 days was undertaken by the Antonio e Margherita Hospital in Tortona, Italy. The results showed that Svetol can assist calorie controlled dieting. In the results, the 30 volunteers taking Svetol after their main meals lost an average of 4.9kg, with the other 20 volunteers not taking Svetol only losing 2.45kg. The results of this study have recently been published in the scientific journal Phytotherapie. These results as shown below - the graph on the left shows the increased weight loss with Svetol, and the graph on the right shows that Svetol also induced a greater change in the Body Mass Index.

As you can see, these studies show that dieting with CoffeeSLENDER may be around twice as effective as dieting alone.  You can read in the testimonial section how CoffeeSLENDER also works for people just like you! To purchase CoffeeSLENDER and boost your diet's results, click here.
