It is argued that you can exhibit good levels of fitness while being overweight. While this is correct, recent research from the US has found that the health benefits associated with fitness are to some degree mitigated by the excess weight. The study found that although they have a lower risk of heart disease than their sedentary overweight counterparts, active overweight females still have significantly higher health risks than normal-weight active individuals. Although being active (a minimum of 30 minutes of activity most days) is important and does contribute to reduced rates of heart attack in comparison to inactive people, it is unfortunately not enough.
