After giving birth to three kids in less than 5 years, I never had much time to sleep. Like most folks, I savor those nights when I can get 6 or 7 hours of shuteye. Now numerous studies tell us that getting our zzz’s also helps with our weight loss efforts.
A 2011 study published in the International Journal of Obesity found that folks trying to shed at least 10 pounds were more likely to achieve their goal if they slept between 6 to 8 hours a night and had lower stress levels.
A 2004 study by the Stanford School of Medicine found that the less you sleep, the more weight you’ll gain. They found that not getting enough sleep leads to higher levels of appetite-stimulating hormones and lower levels of the hormones that tell us when we’re full. Furthermore, lack of sleep was associated with a higher body mass index (BMI).
There are also numerous theories that find sleepless nights can lead to weight gain. One theory says that when you’re tired, you become less physically active during the day which can lead to weight gain. A second theory says that when you’re sleep deprived you don’t care as much to make conscious food choices—which can lead you off your healthy eating plan.
