New Research Finds Interesting Correlations Between Lifelong Weight Gain and Mortality Rates

According to new research, people who start adulthood with a body mass index (BMI) in the “normal” range and move later in life to being “overweight” but not “obese” to tend live the longest.

Those who stayed in the “normal” BMI range throughout life didn’t live as long as the latter category and those who started adulthood as “obese” and continued to add weight had the highest rate of death.

Researchers stated that the impact of weight gain on mortality is complex and depends on lots of factors like the amount of weight gain and where the subjects BMI started.

The primary message is that you want to start in a “normal” weight range and gain only a modest amount throughout life while avoiding “obesity.”

Results like these were also found in two generations of participants in a Framingham Heart Study, though the participants were mostly white. The review followed the medical histories of residents in one city and that of their children for several decades.

The study revealed troublesome trends for the younger generation who became overweight or obese sooner in life than their parents and are more likely to have an obesity-linked death.
