Sleep and Weight Loss

Q: Is it true that getting more sleep could help me lose weight?

A: If you are already getting adequate sleep (six, seven or up to eight hours a night), getting more sleep is unlikely to help you lose weight. However, if like many people you are currently getting too little sleep, more shut-eye might help. A 2008 analysis of studies found that adults who get less than six hours of sleep are about 55 percent more likely to be obese. These associations can’t prove that lack of sleep is what caused excess weight. Yet several studies that followed people for ten to twenty years do link getting less than six or seven hours of sleep a night with greater likelihood of weight gain. Short-term trials tie lack of sleep to changes in hormones that control appetite and to greater perception of hunger. In one recent study, sleep deprivation produced changes in brain activity in the “reward center,” which could explain links between lack of sleep and preference for sweets and other high-calorie foods.

If too little sleep leaves you too tired to be physically active, or more likely to turn to sweets and other foods to perk up your energy, it could increase the calories you consume and decrease calories burned, thus leading to weight gain. On a practical basis, if you stay up late, then more time awake means more time available for eating. Note that it’s getting the right amount of sleep that supports healthy weight. In a study of more than 120,000 people, getting more than eight hours of sleep a night was also linked to long-term weight gain. These links, while important, were small compared to links with changes in eating and physical activity. In other words, keep your focus on healthy habits overall. Get the sleep you need to live a lifestyle that supports health, including a healthy weight.
