Lose fat while you sleep!

Sounds suspiciously like snake-oil, right?

In a randomized, placebo-controlled study involving 19 overweight subjects aged 18-44 years, results indicate that long-term supplementation with mixed isomer conjugated linoleic acid (CLA) may increase fat oxidation and energy expenditure during sleep. The subjects were randomized to 1 of 2 groups for a period of 6 months – 1) CLA group: received 4 g/d of 78% active CLA isomers (3.2 g/d: 39.2% cis-9, trans-11 and 38.5% trans-10,cis-12); 2) placebo group: received 4 g/d of safflower oil. At intervention end, the change in fat oxidation during sleep (0-6 mo) was found to be significantly different in the CLA group (4 g/sleep) from that in the placebo group (-7 g/sleep). Additionally, the percentage of energy from protein during sleep reduced in the CLA group (3.3%) compared with baseline. Furthermore, at intervention end, the change in sleeping energy expenditure in the placebo group (-43 kcal/sleep) was found to differ from that in the CLA group (0 kcal/sleep). Thus, the results of this study suggest that supplementation with CLA may increase fat oxidation and energy expenditure during sleep in overweight subjects.
