Why Sleep Matters Part 3

So does sleep really matter? Absolutely it does! As previously posted, individuals in a study group who were on a calorie controlled diet and also got adequate sleep, achieved higher fat loss than those on the same caloric intake who did not get sufficient sleep. Sleep helps regulate insulin, which pays off in less efficient storage of fat.

But sleep also has some effect on our behaviors too. Especially our eating behaviors. Those who are sleep deprived are more likely to need extra calories in order to feel functional. Their bodies were not able to fully recover during sleep, so more calories are needed for daily activities. This results in more snacking urges and food cravings. Lack of sleep is also affects hormones. Low sleep (ie. 6 hours or less) is associated with higher cortisol and higher ghrelin levels. Both of these hormones are associated with increases in hunger, leading to higher calorie intake and increases in body mass.

Sleep matters! For many things (mental health, mental functioning, energy etc) including body composition and weight management. Aim for 7-9 hours of sleep each night. Make it matter and work for you!
