Diet and exercise: You should be under the care of a health professional who can help you by referral to a good nutrionist and an appropriate exercise program.

Agree w Dr. Dern: Eat healthfully ; be physically active. Aim for 7.5 to 8 hrs of sleep / night. Hydrate w at least 64 oz of water / day. Calories burned must > calories consumed. Do both cardio ; weight training. Consider working with a nutritionist and a trainer.
