Can Sleep Problems Cause Weight Gain

 

Sleep Disorders and Weight Gain | What To Do

Think about it: If you’re feeling sleepy at work, you may be tempted to reach for a cup of coffee (or several cups) and a doughnut for a quick shot of energy. Later you may skip the gym and pick up takeout on your way home to your family -- no time to cook. When you finally find yourself back in your bed, you are too wound up to sleep.

It’s a vicious cycle, and eventually this sleep deprivationcan sabotage your waistline and your health.

It starts out innocently enough. “When you have sleep deprivation and are running on low energy, you automatically go for a bag of potato chips or other comfort foods,” saysSusan Zafarlotfi, PhD, clinical director of the Institute for Sleep and Wake Disorders at Hackensack University Medical Center in New Jersey.

The immediate result? You may be able to fight off sleepiness. The ultimate result? Unwanted pounds as poor food choices coupled with lack of exercise set the stage for obesity and further sleep loss.“Sleep debt is like credit card debt,” Zafarlotfi says. “If you keep accumulating credit card debt, you will pay high interest rates or your account will be shut down until you pay it all off. If you accumulate too much sleep debt, your body will crash.”

Not getting enough sleep is common -- even talked about with pride -- in the U.S. “We brag about an all-nighter, but we do pay a price for staying up late and getting up early,” says Mark Mahowald, MD, director of the Minnesota Regional Sleep Disorders Center in Hennepin County.

Understanding the Sleep-Diet Connection

The sleep-diet connection is regular fodder for diet books and magazine articles. Maybe you have even heard about the sleep diet, which suggests you can lose weight while you catch your ZZZs.

On average, we need about 7.5 hours of quality sleep per night, he says. “If you are getting this already, another half hour will not help you lose 10 pounds, but if you are a five-hour sleeper and start to sleep for seven hours a night, you will start dropping weight.”

Exactly how lack of sleep affects our ability to lose weight has a lot to do with our nightly hormones, explains Breus.

The two hormones that are key in this process are ghrelin and leptin. “Ghrelin is the ‘go’ hormone that tells you when to eat, and when you are sleep-deprived, you have more ghrelin,” Breus says. “Leptin is the hormone that tells you to stop eating, and when you are sleep deprived, you have less leptin.”

More ghrelin plus less leptin equals weight gain.
