Lack of Sleep May Hinder Weight Loss

Does lack of sleep influences our weight loss or even weight gain?

Humans need sleep. Sleep restores energy, allowing the body to function day after day. Not getting enough sleep can be harmful.
Lack of sleep, or sleep deprivation, has been linked to a variety of negative health effects, such as poor memory, compromised immune system function, high blood pressure, irritability, dizziness, and headaches.

We All Need Sleep but Some of Us Need Less

The amount of sleep people need varies, but commonly it is recommended that adults get at least 7 hours of sleep each night.
Other risks associated with lack of sleep include weight-gain and obesity. So for individuals looking to lose weight, getting sufficient sleep is especially important.

And writing in the Annals of Internal Medicine, researchers found lack of sleep in dieters may prevent them from losing as much body fat as they otherwise would if they were getting enough sleep.

For the study, 10 overweight men and women lived in a sleep lab for two separate two-week periods. Both weeks the participants were kept on a calorie-restricted diet, but for one week the individuals slept for 8.5 hours per night, then the other week, study participants only received 5.5 hours of sleep each night.

Results showed that dieters lost the same amount of weight under both sleep conditions, but during the sleep-restricted week, the individuals lost muscle rather than body fat.

What did the researchers  of the Study find?

 When participants’ sleep was restricted to only 5.5 hours each night, they lost less body fat and more lean body mass than when they slept 8.5 hours—the opposite of what is considered optimal in a calorie-restriction (dieting) program. Participants with restricted sleep also reported feeling more hunger.

So to ensure the best weight loss, the scientists suggest people pay more attention to their daily routines; diet and exercise habits, and of course, sleep.”
