Brown Fat Activation Study

This is an open lable, pilot study in which the investigator will research the effect of two FDA approved drugs, Mirabegron and Pioglitazone on fat tissue. Pioglitazone is drug approved by the FDA for the treatment of diabetes and Mirabegron is a drug that is approved by the FDA for the treatment of overactive bladder.
