Hey everybody, just wanted to pass on some info re: weight loss. I saw the posts on FB. There is huge evidence that poor sleep is very much related to weight. Here is part of an article I copied and pasted from APA (I did the bolding):
The cardiometabolic trap
Subsequent studies have confirmed the effects of partial sleep loss on hormone regulation and have led to a burgeoning of research on the role of sleep in obesity, diabetes and cardiovascular disease a tangled triumvirate of sickness and mortality that are key elements of what researchers sometimes refer to as cardiometabolic disease. In a 2012 article published in the American Journal of Human Biology, UC biomedical anthropologist Kristen Knutson, PhD, reviewed research on sleep and cardiometabolic health and concluded that sleep restriction leads to "substantial and clinically significant changes in appetite regulation, hunger, food intake, glucose metabolism and blood pressure control." Knutson also found a significant association between short sleep duration (less than six hours per night, in most studies) and either more obesity or a higher body mass index. Adolescents and children showed a stronger association, suggesting they may be especially vulnerable to the effects of lost sleep.
One way in which lack of sleep may thwart cardiometabolic health is by skewing people's dietary choices. In a 2011 study published in the American Journal of Clinical Nutrition by a large multicenter team, healthy men and women who were restricted to just four hours of sleep per night over six nights took in significantly more calories, particularly from fat, than their well-rested counterparts and they didn't make up for it by burning more energy.
Another study, conducted by Arlet Nedeltcheva, MD, and colleagues at UC and published in the American Journal of Clinical Nutrition in 2009, found that adults who were allowed to sleep only 5.5 hours per night for two weeks indulged in more snacks than their counterparts who enjoyed 8.5 hours of sleep each night. Likewise, in a 2012 yet-to-be-published study that drew on data from the CDC's 200708 National Health and Nutrition Examination Survey, Knutson, Grandner and colleagues mapped dietary patterns to sleep complaints including difficulty falling asleep, difficulty staying asleep, non-restorative sleep and daytime sleepiness. Every complaint, they found, was significantly associated with greater total caloric intake.
In a 2012 study published in the Annals of Internal Medicine, a team of UC researchers uncovered a molecular clue to how lack of sleep might promote diabetes: Fat cells in people who don't get enough sleep have a 30 percent reduced ability to respond to insulin. Fortunately, the biochemical processes that sleep loss sets in motion may reversible, at least if skipping sleep doesn't become a lifelong habit. In September, psychologist Karen Matthews, PhD, of the University of Pittsburgh, reported in SLEEP that if teens who normally got six hours of sleep per night were allowed just one extra hour of sleep, their insulin resistance improved by 9 percent.
So if you are trying to lose weight for the cruise, make sure you get good sleep (which is literally supposed to be 8 hours)!
Good night!
Very interesting! Wonder if that's why Freshmen in college tend to gain weight, hence the freshmen 15.
