Efficacy of Olibra: A 12 Week Controlled Trial

Study Overview
=================
Brief Summary
-----------------
Today's obesogenic environment, favors behavioral choices that lead to an excess of energy intake over expenditure, and consequently weight gain. Intervention strategies that harness the body's own appetite and satiety regulating signals could provide an effective means of countering excessive energy intake. The purpose of this study was to investigate whether a vegetable oil emulsion (Olibra) would result in weight loss that was associated with a reduction in food intake.

Detailed Description
-----------------
71 healthy subjects were enrolled (60 females, 11 males; Age: 18 - 60 years, BMI 25 - 40 kg/m2) in a two-phased, randomized, placebo-controlled, double-blind, parallel trial. During a 12-week period, Olibra was compared with a placebo (milk fat). Food intake testing was conducted on three days and anthropometric data was collected on 7 days. Key outcome measures were, body weight, body composition, energy intake, and appetite ratings.
