    A new study on physical activity that involved more than half a million participants over age 40 found that modest exercise increases life expectancy regardless of weight.

    Contrary to most of the attention given to obesity as the crucial risk factor for health, the study found that an active lifestyle increased life expectancy to a greater extent than a lower body mass index (BMI), in general. In fact, participants who were active but class 1 obese lived an average of 3.1 years longer than those who were at a normal weight but didn’t engage in physical activity. This is in-line with reports from earlier this year that excessive sitting is unhealthy and that reducing excessive sitting to less than 3 hours a day alone can improve longevity by 2.0 years.

    The article states low level of physical activity of moderate to vigorous intensity would confer a 1.8-year gain in life expectancy after age 40, compared with no activity. A low level of physical activity is defined as up to 75 minutes of fast walking per week.

    A consequence of this study is that it calls into question the reliance on BMI to assess fitness. That isn’t to suggest that BMI isn’t a factor, but that what we’ve heard for years in the media that being overweight is “bad” for you while exercise is “good” is a flawed message. A better message would be: Regular exercise is essential to longevity and a lower BMI helps too — do the first and the other will likely follow.
