New Data Shows Fitness Trumps Weight Loss for a Longer Life

Which matters more for a long life: diet or exercise? New health data suggests that fitness might be the key to greater longevity. Doctors often focus too much on body weight alone. However, high levels of cardiorespiratory fitness offer unique health benefits. This is true even if you don’t lose much weight.

Studies confirm that exercise slows the aging process. For instance, aerobic activity, like cycling or running, improves blood flow to the brain. This can boost cognitive health and self-control. One’s fitness level, often measured by VO2 max, is a powerful predictor of living longer.

Diet remains extremely important. A healthy eating pattern, such as the Mediterranean diet, reduces inflammation and chronic disease risk. Ultimately, the best strategy combines both. You need healthy foods to reduce fat and disease risk. You need regular movement to strengthen your heart and brain. Focus on consistency. Start with moderate activities you enjoy to gain the most long-term wellness benefits.
