Has stable body weight, i.e., not varying by >3% within 3 months prior to study.
Has not been treated over the past 3 months or is currently treated with any of the following medications: Oral contraceptives (female subjects); Hormone replacement therapy (female subjects); Metformin for the treatment of polycystic ovary syndrome (female subjects); Antihypertensive agents; Lipid-lowering agents; Thyroid replacement therapy; selective serotonin reuptake inhibitors (SSRIs).
