Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates whether supplementations with a highly bioavailable green tea extract may help obese women to counteract weight regain after a 3-month weight loss intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Most obese subjects regain weight after weight loss due to compensatory adaptations finalized to maintain stable body energy stores. In lean or obese individuals, maintenance of a 10% or greater reduction in body weight is associated with a decline in 24-hour energy expenditure of approximately 20%-25%. The restraint of the energy expenditure decline during dieting by green tea (GT) preparations should be a useful strategy to facilitate weight maintenance. To increase absorption of GT, the investigators used a formulation with phospholipids (Greenselect Phytosome® ) added with piperine, a thermogenic agent and a booster of absorption for various phenolics.

At the end of a 3-month lifestyle intervention, all patients giving written informed consent were randomly assigned to two groups for the weight-maintenance phase: 20 of them were supplemented twice a day for 3 months with a dietary supplement (Globes®, Pharmextracta, Pontenure, Piacenza, Italy) and 20 with placebo.Women were blind to the supplementation throughout the whole trial. All women attended a monthly clinical visit during the supplementation period and 3 months after the end of supplementation.
