Often there is debate about whether diet, exercise, or a combination of the two is most effective for improving heart health in the overweight population. A new study published in the American Journal of Clinical Nutrition shows that it is actually the weight loss that provides cardiovascular benefits, and the mode of achieving the weight loss is irrelevant. Exercise and diet are both important, and it is always beneficial to make healthy dietary choices and to start an exercise regimen. The take home message from this study is that is it important to achieve an optimal weight, and anything you do to start this process will yield cardiovascular benefits. It is just another example of how obesity has negative affects on health.
