How sleep is very underappreciated

adults who sleep less than five or six hours a night are at higher risk of being overweight. Among children, sleeping less than 10 hours a night is associated with weight gain.

Losing just a few hours of sleep a few nights in a row can lead to almost immediate weight gain

staying up late and getting just five hours of sleep increased a person’s metabolism. Sleep-deprived participants actually burned an extra 111 calories a day

But even though we burn more calories when we stay awake, losing sleep is not a good way to lose weight

Staying up late and skimping on sleep led to not only more eating, but a shift in the type of foods a person consumed.

We found that when people weren’t getting enough sleep they overate carbohydrates

They ate more food, and when they ate food also changed. They ate a smaller breakfast and they ate a lot more after dinner.

sleep-deprived eaters ended up eating more calories during after-dinner snacking than in any other meal during the day. Over all, people consumed 6 percent more calories when they got too little sleep. Once they started sleeping more, they began eating more healthfully, consuming fewer carbohydrates and fats

insufficient sleep changed the timing of a person’s internal clock, and that in turn appeared to influence the changes in eating habits.

lack of sleep alters the biology of fat cells.

Metabolically, lack of sleep aged fat cells about 20 years
