Physical inactivity can Lead to energy imbalance (e.g., expend less energy through physical activity than consumed through diet) and can increase the risk of becoming overweight or obese. Increase the risk of factors for cardiovascular disease, including hyperlipidemia (e.g., high cholesterol and triglyceride levels), high blood pressure, obesity, and insulin resistance and glucose intolerance. Increase the risk for developing type 2 diabetes. Increase the risk for developing breast, colon, endometrial, and lung cancers. Lead to low bone density, which in turn, leads to osteoporosis.
