What is a healthy body mass index (BMI) for staying young?

Dr. Michael Roizen, MD
Internal Medicine
The average body mass index (BMI) for Americans is 27.2 kg/m2 (kilograms per meter squared). In terms of age reduction, the ideal BMI is 23 or less. As long as your weight is not abnormally low because of some health complication, such as a chronic disease, if you have a BMI of 23 or less, you can expect your RealAge (physiologic age) to be as much as eight years younger than if your BMI were at the national average of 27.2. If your BMI is over 25, you will probably want to consider a moderate weight-loss program that includes boosting physical activity and cutting caloric intake. If your BMI is over 27, excess weight is probably causing you unnecessary aging, and, again, you should consider a safe and gradual weight-loss plan involving exercise and cutting calories. People with BMIs over 30 should consult a physician or weight-loss professional prior to beginning any diet, to establish a safe and practical weight-loss plan.
