How Sleep Impacts Body Weight

How Sleep Impacts Body Weight Sleep duration can influence the amount of food you consume and the number of calories you burn off every day. The results of a study conducted with 223 adults between the ages of 21 and 69 found that getting fewer than 6 hours or more than 9 hours of slumber can weigh heavily on your waistline, and for different reasons. Findings were published in The Journal of Nutrition.

After determining the average sleep duration for each subject, the amount of calories they consumed, individual levels of physical activity and metabolic rates, researchers determined that although those who got less than 6 hours of sleep tended to be more active than those who slept an average of 8 hours, they consumed significantly more calories. On the other hand, subjects who slept in for 9 hours or longer tended to consume fewer calories during the day and expend less energy than the 8-hour-per-day sleepers.

True Strength Moment: Any way you look at it, sleeping for less or longer than the recommended 8 hours per night appears to promote energy imbalance. And when you don't burn up enough calories, or consume more than you should, it becomes more difficult to manage body weight.
