Being overweight or obese leads to insulin resistance, accelerating the development of diabetes, high blood pressure, heart disease, stroke, liver and kidney disease. It ages your body faster, robs you of energy, makes you short of breath, and puts you at risk for obstructive sleep apnea. It increases risk for a number of different cancers!
This weight problem affects not only you, it also affects your family. The risk to children becoming obese in a household where at least one parent already is obese is somewhat under 50%, but approaches up to 80% in households where both parents are obese.
