Obesity and Life ExpectancyIt seems being obese can have a similar impact on life expectancy. For people aged 40-45, the loss of life expectancy from being obese was 8 to 10 years. How do we know this? Well, an article was published in the Lancet, a prestigious British medical journal that examined 57 studies (almost one million people) that looked at the connection between body-mass index (or BMI) and life expectancy.
How “Big” are These Problems?According to the Centers for Disease Control (CDC), about 20% of adults in the U.S. smoke. That number is a shocking to me. Of course, that number is less than it was years ago, but represents a large number of the population. For obesity, the National Institutes of Health (NIH) estimates that one-third of the U.S. population is obese, making the U.S. the fattest society that the world has ever known. By simply not smoking and keeping your weight normal, you can add years to your life. Here are a couple of things to try to help you:
