Rats fed a high carbohydrate diet containing 10 or 100 ppm cimaterol for 4 weeks gained 41% to 59% less fat and 70% to 76% more protein than controls, with no major changes in either energy gain or efficiency of energy retention. Effects of cimaterol on lipid metabolism in these rats were assessed. Cimaterol stimulated lipolysis in vivo and in vitro, but failed to influence rates of de novo fatty acid synthesis in either liver or white adipose tissue. Activities of fatty acid synthetase and malic enzyme in these tissues were also unaffected by cimaterol. Cimaterol administered in vivo failed to affect lipoprotein lipase activity in white adipose tissue, but elevated enzyme activity 67% to 75% in the extensor digitorium longus muscle. Lipoprotein lipase activity in the extensor digitorum longus muscle was also elevated by 66% during a 2 hour incubation with 1 mmol/L cimaterol. We conclude that cimaterol selectively stimulates both lipolysis in white adipose tissue and lipoprotein lipase activity in skeletal muscle, to direct energy away from adipose tissue deposition toward skeletal muscle accretion.
