Weight loss either by dieting or exercising has healthy heart benefits according to a new study. Researchers found that losing weight, regardless of the method, appears to help restore the hearts elasticity allowing it to more easily relax and contract. As we age, the tissues of the body including the heart and arteries accumulate collagen fibers making these tissues stiffer - less likely to relax and more difficult to contract. While it was previously found that diet and exercise combined result in heart benefits, this study now suggests either one will help restore cardiovascular elasticity. Researchers suggested that individuals who lose weight in any healthy manner that they find most tolerable will reap the heart benefits.
