Physical inactivity and restless sleep exacerbate genetic risk of obesity


"They found the strongest evidence to date of a modest gene-activity interaction. For example, for a person of average height with 10 genetic variants associated with obesity, that genetic risk accounted for a 3.6 kilogram increase in weight among those who were less physically active but just 2.8 kilograms among those who were more active. Results were similar in analyses of sleep patterns; among participants with some genetic risk of obesity, those who woke up frequently or slept more restlessly had higher BMIs than those who slept more efficiently.
The researchers are currently examining whether this interaction between genetics and  differs between men and women. They are also studying the effects of patterns of activity - for example, whether a consistent level of moderate activity has different effects from overall low levels punctuated by periods of vigorous ."
