Study Arms:
- Metformin (Type: EXPERIMENTAL): Subjects randomized to the metformin treatment group will receive 1000 mg extended release metformin hydrochloride tablets (Bristol Myers Squibb) twice per day with food approximately 8 hours apart.
- Dietary Restriction (Type: EXPERIMENTAL): Subjects randomized to the dietary restriction group (DR) will reduce their energy intake by 25% from their weight maintenance energy intake determined at baseline by doubly labeled water.There will be no gradual ramping of dietary restriction. The 25% energy reduction goal will apply from the first day of the intervention for a period of 24 weeks. Subjects will be asked to not modify their normal level of physical activity.
- Exercise (Type: EXPERIMENTAL): Subjects randomized to the exercise training group will complete a structured program of aerobic training 3 to 4 times per week and resistance exercises 2 times per week.
- Control (Type: NO_INTERVENTION): Subjects randomized to the no treatment control group will be asked to continue, as normal their usual dietary and exercise regimen. Subjects will be asked to not begin diet or exercise regimens through the 24-week study or to begin medical treatment for PCOS.
