You know the drill: Eat right and exercise to lose weight. It can be a tiring endeavor to find the time to prepare healthy meals and carve out a few minutes to work out. Plus, you've still got work, family and a life to live.

When we get busy, we tend to shave time off our sleep schedule to fit everything in. This may not only be unhealthy, but could also be counterproductive to your weight-loss efforts. Recent research has found a strong relationship between sleep and weight loss.

"The more you sleep, the better your body can regulate the chemicals that control hunger and appetite," according to Michael Breus, Ph.D., a clinical psychologist, board certified sleep specialist and author of Good Night: The Sleep Doctor's 4-Week Program to Better Sleep and Better Health.

"Sleep deprivation makes you feel hungry, even if you are full," says Dr. Breus. "Sleep loss has been shown to affect the secretion of cortisol, a hormone that regulates appetite. As a result, individuals who lose sleep may continue to feel hungry despite adequate food intake."

The Journal of the American Medical Association has published several studies suggesting that a lack of sleep may increase hunger and affect the body's metabolism, which may make it more difficult to maintain or lose weight.

Research from a study conducted at Columbia University found that, "The more sleep deprived you are, the more likely you are to become obese." Participants between the ages of 32 and 59, who slept four hours or fewer each night were 73 percent more likely to be obese than those who got between 7-8 hours.

"Sleep loss may interfere with the body's ability to metabolize carbohydrates, which leads to high levels of blood sugar," says Dr. Breus. "Excess blood sugar promotes the overproduction of insulin, which can lead to the storage of body fat and insulin resistance, a critical step into the development of diabetes."

Dr. Breus adds that when someone is sleep deprived, they tend to make poor food choices. People are apt to choose high-sugar, high-caffeine and high-carbohydrate snacks to get a burst of energy, all of which contribute to weight gain.

He breaks it down like this: "Sleep deprivation causes an increase in appetite and a decrease in metabolism, which equals an increase in fat storage and weight gain."

Try getting an extra hour of sleep per night to see how it affects your energy, mood and weight-loss efforts. Dr. Breus says that individual sleep needs vary, but suggests most adults need 6-8 hours per night.

An extra hour of sleep may burn as many as 147 additional calories per night, according to Dr. Breus. The more sleep you get, the more your metabolism speeds up, which could lead to losing as much as 14 pounds a year -- simply from getting a little extra sleep every night.
