Treatment with the selective beta3-adrenoceptor agonist CL 316,243 increases insulin-mediated glucose disposal (IMGD) and fat oxidation in lean human males, without altering energy expenditure or body weight.

Taking CL 316,243 (1,500 mg/day) for 8 weeks improves how your body handles insulin and increases the amount of fat you burn during the day, even without changing your total calorie burn or losing weight. This effect is strongest in lean individuals and depends on maintaining the drug's presence in your blood.

GoodSupportsHIGH confidence
We conclude that treatment of lean male subjects with CL 316,243 increases insulin action and fat oxidation, both in a plasma concentration–dependent manner.
