CLA Shows Weight Management Benefits
Lee Swanson Research Update
CLA supplementation for seven months was found to reduce body fat mass by 0.5 percent and total body weight by 0.1 percent, compared to increases of 1.3 and 0.4 percent in the placebo group, respectively, according to findings from a randomized, double-blind, placebo-controlled trial published in the American Journal of Clinical Nutrition.
Although numerous previous studies have reported the potential benefits of CLA for weight management, the new study is said to be the first to report the body fat-lowering effects of CLA in overweight and obese children.
Researchers led by Dale Schoeller from the University of Wisconsin recruited 53 prepubertal children between six and 10 years old and randomly assigned them to receive either CLA (three grams per day) or placebo in chocolate milk for seven months.
At the end of the study, in addition to the beneficial changes in body fat and body weight, the researchers noted that children in the CLA group had lower increases in BMI or 0.5 kg/m2, compared to the placebo group, which had an average BMI increase of 1.1 kg/m2. Furthermore, abdominal body fat was also less in the CLA group than the placebo group, noted Schoeller and his co-workers.
On the other hand, HDL cholesterol levels decreased more following CLA supplementation, and bone mineral accretion was also lower.
The researchers concluded: "Long-term investigation of the safety and efficacy of CLA supplementation in children is recommended."
