Can you tell me if i could lose weight with pcos problem?

Yes: Women with PCOS respond to weight loss via calorie counting. Diet should be first then exercise. You want a low calorie diet: Weight watchers, counting calories, etc. The goal is to break the cycle of increased insulin levels associated with the elevated calories. Usually you want to be eating 1200-1400 calories to lose weight. Once the weight is off then increase to a maintenance caloric amount

It's difficult: but you can still lose weight through dietary restriction and increased exercise. Metformin can help reduce the basic metabolic problem of insulin resistance. Discuss w/your doctor.
