Le Svetol ®, un extrait de café vert décaféiné, induit une perte de poids et augmente le ratio masse maigre sur masse grasse chez des volontaires en surcharge pondérale
Svetol®, green coffee extract, induces weight loss and increases the lean to fat mass ratio in volunteers with overweight problem
In order to test the effects of Svetol®, a green coffee extract with specific ratio between 5-caffeoylquinic acid and others caffeoylquinic acid isomers, on weight loss, 50 volunteers with body mass index superior to 25 were selected. They were randomized in two groups, control group (n = 20) receiving placebo, treated group (n = 30) receiving Svetol® with bland low calory diet. Each volunteer took one capsule of Svetol® or placebo twice a day with main meal, for 60 days. Changes in weight, body mass index (BMI), Muscle Mass/Fat Mass ratio (MM/FM) and self-evaluation of physical aspect were recorded at To and T60. After 60 days of treatment, a significant reduction in weight of 4.97 +/- 0.32 kg (5.7 %) was observed in the Svetol® group compared to control group (p < 0.001). Moreover, MM/FM ratio was increased significantly in Svetol® group compared to control group : 4.1 +/-0.7 %vs 1.6 +/- 0.6 respectively (p < 0.01). The significant decrease of weight and increase of MM/FM ratio showed that Svetol® is able to exacerbate effect of a bland low caloric diet in volunteers who have overweight. This effect could be explained by increasing the consumption of fatty deposits and by preventing them from being accumulated.
