The purpose of this study is to evaluate whether serum markers of inflammation and thrombosis, which ultimately increase cardiovascular risk (CRP, fibrinogen and others) are already abnormal in obese children that do not yet have other features of the metabolic syndrome. The investigators will assess the status of these risk factors in pubertal and prepubertal children ages 8-18 years, both lean and obese. The pubertal cohort that has elevations in these markers will participate in a longitudinal interventional study with lifestyle modification (diet and structured exercise) with or without Metformin for 6mo in a cross over design. Intrahepatic fat contents will be measured as well. The investigators hypothesize that obese children in these age groups will have increased cardiovascular risk related to their obese state before reaching the currently defined criteria of metabolic syndrome. The investigators hypothesize that these cardiovascular risks can be reduced with lifestyle and drug interventions.
