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.

Primary Outcome Measures:
  • Body weight [ Time Frame: 12 weeks ]
    Treatment to determine if test product causes weight loss

Secondary Outcome Measures:
  • Body composition [ Time Frame: 12 weeks ]
    To determine if treatment causes a reduction in body fat mass

Enrollment: 82

Study Completion Date: November 2006
Primary Completion Date: November 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Test
Subjects consumed a vegetable oil emulsion in yogurt at a food intake test and were asked to consume the product twice daily for 12 weeks.
Dietary Supplement: Olibra
Fractionated palm oil and fractionated oat oil in the proportion of 95:5
Other Name: Fabuless
Placebo Comparator: Control Group
Subjects were given a placebo of milk fat in yogurt at food intake tests and asked to consume the placebo twice daily for 12 weeks.
Other: Placebo
100% milk fat

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.
