Expert says that being sleep deprived leads to weight gain, other disorders

URBANA, Ill. – Almost a third of Americans don’t get enough sleep, and that increases their risk of weight gain, diabetes, hypertension, high cholesterol, heart attack, and stroke, said Michael A. Grandner, an expert in behavioral sleep medicine and the keynote speaker of the University of Illinois’s Division of Nutritional Sciences recent Nutrition Symposium.

“Both people who sleep too little and people who sleep too much —seven to eight hours is the gold standard for adults—have a higher mortality rate,” he noted.

According to Grandner, the link between short sleep and obesity has been well documented by at least 65 studies, with the Nurses’ Health Study showing that people who sleep six hours or less are more likely to gain an approximate 33 pounds over the course of 16 years. Short sleepers are 20 percent more likely to have hypertension, and they are 30 percent more likely to develop diabetes.

Because sleep and diet are both biological imperatives, it’s no surprise that one affects the other, he noted. Inadequate sleep promotes inflammation, which can lead to difficulty regulating insulin and an increase in the hunger hormones leptin and ghrelin.

Short sleepers tend to consume more calories, snack more, eat fewer vegetables, and eat more fast food later at night, he said.

“Just as we have healthy diet interventions, we should have sleep interventions. But how do you teach people to get better sleep? It’s hard to get people to sleep more. You’re asking them to give up what little autonomy they have left in their lives. They would trade sleep for work or for their commute, but not for leisure, which they don’t want to give up,” Grandner said.

Further, Grandner said that the less sleep people get, the more impaired they are, and they don’t necessarily realize it—so that drowsy driving is a real problem on our highways. The deficits due to sleep loss add up over time, and after two weeks of skimping on sleep, short sleepers don’t adjust, they get worse, he said.

Lack of sleep is associated with high stress, moodiness, and impaired decision making, he said.

“Sleep-deprived people may not be able to discern what is relevant and irrelevant when making decisions, and they are more likely to engage in risky behavior,” he said.

Short sleepers are also more likely to have memory problems. “I tell my students if they’re going to pull an all-nighter, don’t do it the night before the test. Do it the night before the night before the test. They’ll remember more of what they studied,” Grandner said.

The sleep scholar is also concerned that there is a strong association between food insecurity and sleep difficulties. Problems include difficulty falling asleep, frequent awakenings, and daytime sleepiness. “Hungry people are likely to also be sleep-impaired people,” he said.

Grandner is an instructor in the Department of Psychiatry at the University of Pennsylvania. After earning a Ph.D. in clinical psychology from the joint doctoral program at San Diego State University and the University of California, he completed a postdoctoral fellowship in sleep and circadian neurobiology and a fellowship in behavioral sleep medicine, both at Penn. He has been honored by the Society of Behavioral Sleep Medicine, the Sleep Research Society, and the American Heart Association, and has written extensively about sleep and health.

Expert on sleep and obesity will speak at U of I Nutrition Symposium

Published February 24, 2015

URBANA, Ill. – Is there a relationship between sleep and obesity? University of Pennsylvania professor Michael A. Grandner will answer this question in his keynote address at the 2015 Illinois Nutritional Sciences Graduate Student Association Nutrition Symposium on Thursday, March 19, from 4 to 5 p.m. in 180 Bevier Hall on the University of Illinois campus. The event is open to the public.

“Dr. Grandner is board certified in behavioral sleep medicine, and his research focuses on how sleep and sleep-related behaviors are related to cardiovascular disease, diabetes, obesity, neurobehavioral functioning, mental health, and longevity. He is also studying the social, environmental, and behavioral factors that determine how we sleep,” said Jessica Hartke, assistant director of the U of I Division of Nutritional Sciences (DNS).

According to the expert, over 60 studies have reported an association between short sleep duration and obesity. He will examine a number of physiological, behavioral, and dietary factors that may contribute to this association.

Grandner is a professor in the Department of Psychiatry at the University of Pennsylvania. He earned his Ph.D. in clinical psychology from the joint doctoral program at San Diego State University and the University of California, then completed a postdoctoral fellowship in sleep and circadian neurobiology, an accredited fellowship in behavioral sleep medicine, and a master’s degree in translational research, all at Penn.

He serves on the Mental Health Task Force for the National Collegiate Athletics Association (NCAA) and has received honors and awards for his work from the Society of Behavioral Sleep Medicine, Sleep Research Society, American Academy of Sleep Medicine, American Heart Association, Population Association of America, and other groups. He has also published over 50 articles and chapters on issues related to sleep and health.

A mini-symposium, “Nutritional Sciences: Impacting Health at Every Age,” featuring world-class University of Illinois faculty researchers, will be featured before the keynote address. That event will take place from 12:45 to 2:45 p.m. in the Monsanto Room at the Agricultural, Consumer and Environmental Sciences (ACES) Library, 1101 South Goodwin Avenue, on campus.

The panel will include Yuan-Xiang Pan, speaking on “Maternal Nutrition Programs: Physiological Consequences through Epigenetics in Animal Models”; Sharon M. Donovan, “Breastfeeding Reduces Circulating Inflammatory Cytokines and Inflammatory Gene Pathways in Immune Cells Compared to Formula Feeding in the First Six Months of Life”; Margarita Teran-Garcia, “Emerging Adulthood: An Opportunity to Prevent Chronic Disease”; and Karen Chapman-Novakofski, “Nutrition and the Older Adult.”

DNS graduate students will compete in an oral research presentation composition from 9:15 to 11:30 a.m. in the Monsanto Room of the ACES Library, and poster research presentation and competition will be from 5:15 to 6:40 p.m. in the ACES Library Heritage Room. Both are open to the public.

The Nutrition Symposium is sponsored by Abbott Nutrition; The Beef Checkoff; Kraft Foods Group, Inc.; Mead Johnson Nutrition; PepsiCo, Inc.; Tate & Lyle; and Wrigley. Friends of the symposium are Campbell Soup Company, Kemin Health, U of I College of ACES Office of Research, and U of I Departments of Animal Sciences, Food Science and Human Nutrition, and Kinesiology and Community Health. Funding is also provided by the U of I Student Organization Resource Fee.

“Our graduate students take full responsibility for planning and executing the Nutrition Symposium,” said Rodney Johnson, DNS director. “The event provides our students with an important professional development opportunity. I’m pleased that they have organized a wonderful program that can be enjoyed by the community.”
