Although diet and exercise programs usually dominate the weight loss headlines, research suggests that your sleep habits may be just as important.

The latest piece of research showing a link between sleep habits and weight gain appeared in the June 10, 2019 issue of JAMA Internal Medicine.

This paper found that exposure to artificial lighting at night predicted weight gain over 5 years of follow-up among more than 43,000 women. This article, however, is merely the latest of hundreds of scientific papers from the last decade indicating that poor sleep makes it easier to gain weight and harder to lose weight.
