Effect of a vegetable-oil emulsion on body composition; a 12-week study in overweight women on a meal replacement therapy after an initial weight loss: a randomized controlled trial.
Study Goal
The researchers aimed to determine if a vegetable-oil emulsion in a meal replacement could aid weight maintenance and reduce body fat mass after initial weight loss.
Results Summary
The study found no significant difference in weight loss between the vegetable-oil and control groups, but the vegetable-oil group showed a greater reduction in body fat mass (1.7% vs. 0.8%).
Population
Subjects who lost >5% body weight after a 6-week very low calorie diet.

| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
partial meal replacement diet containing a vegetable-oil emulsion (test) | decrease | weight | subjects with >5% body weight (BW) loss | 1.0 ± 2.1 kg | A significant weight loss was observed | #1 |
partial meal replacement diet containing dairy fat (control) | decrease | weight | subjects with >5% body weight (BW) loss | 1.3 ± 2.1 kg | A significant weight loss was observed | #2 |
partial meal replacement diet containing a vegetable-oil emulsion (test) | decrease | Body fat mass (BFM) | subjects with >5% body weight (BW) loss | --1.7% | decreased significantly | #3 |
partial meal replacement diet containing dairy fat (control) | decrease | Body fat mass (BFM) | subjects with >5% body weight (BW) loss | --0.8% | decreased | #4 |
Addition of a vegetable-oil emulsion to a meal replacement weight maintenance program after an initial weight loss using VLCD | decrease | Body fat mass (BFM) | subjects with >5% body weight (BW) loss | by 0.9% | was associated with decreased BFM | #5 |
Addition of a vegetable-oil emulsion to a meal replacement weight maintenance program after an initial weight loss using VLCD | no change | BW | subjects with >5% body weight (BW) loss | - | without any change | #6 |
PURPOSE: The maintenance of an obtained lower weight level is often found to be difficult. The aim of this study was to determine weight maintenance after an initial weight loss by consumption of a meal replacement with a vegetable-oil emulsion associated with prolonged satiety. METHODS: After a 6-week weight loss period with very low calorie diet (VLCD), subjects with >5% body weight (BW) loss were randomized to a 12-week weight maintenance follow-up period, comparing a partial meal replacement diet containing a vegetable-oil emulsion (test) or dairy fat (control). Anthropometric data and safety variables were collected at baseline and after 4, 8 and 12 weeks. RESULTS: A significant weight loss was observed during the 12-week weight maintenance diet in the test and control group, respectively; 1.0 ± 2.1 kg (p < 0.05) versus 1.3 ± 2.1 kg (p < 0.05) with no significant difference between the groups. Body fat mass (BFM) decreased significantly (p < 0.05) in the test group (--1.7%) compared to the control group (--0.8%). CONCLUSIONS: Addition of a vegetable-oil emulsion to a meal replacement weight maintenance program after an initial weight loss using VLCD was associated with decreased BFM by 0.9% without any change in BW between the two groups.
