Weight loss was once considered a straightforward calculation: eat less and move more to create a calorie deficit. Now, fundamental differences between people – in genetics, health conditions, body type and more – are also thought to affect how difficult it’s to reduce weight. Yet research shows that certain aspects may also help determine success.
Sleep more to eat less? New research expands on this premise, suggesting that adults who’re higher rested eat significantly fewer calories than those that are chronically sleep deprived.
Dr. Beth Frates, director of lifestyle medicine and wellness on the Department of Surgery in Massachusetts, says this short-term study of 80 obese people drives home that sleep — or the shortage of it — plays a job in our tendency to placed on extra kilos. How essential is it? General Hospital.
“Finding ways to clean up sleep hygiene can help people increase the recommended seven to nine hours of sleep per night,” says Dr. Frates. “As a result, fewer calories may be consumed and even weight loss may occur in people who are in the overweight category according to BMI.”
Lack of sleep is linked to chronic diseases.

Dr. Frates notes that almost one-third of Americans don't get the advisable seven to nine hours of sleep each night, and that lack is linked to many chronic diseases, including hypertension, heart disease, diabetes and obesity. She says sleep is considered one of the six pillars of lifestyle medicine — a listing that also includes exercise, nutritious food, stress reduction, social connection, and avoidance of risk aspects.
“Most people focus on exercise and diet when it comes to weight management and a healthy heart, but some people focus on sleep,” she says.
Tracking sleep cycles, calories and weight
Study participants were adults between the ages of 21 and 40 with a BMI between 25.0 and 29.9, which is taken into account obese. All of them routinely slept lower than 6.5 hours per night. For the primary two weeks, everyone maintained a traditional sleep pattern.
For the second two weeks, the participants were randomly divided into two equal groups. With the goal of accelerating sleep hours to eight.5 hours, one group received individual counseling that identified ways to vary sleep disruptors related to bed partners, children, and pets.
“The advice was not generalized,” notes Dr. Frates. “It was specific to that person, and then there was a follow-up visit with more counseling.” Another group of participants continued with their typical sleep habits.
All were asked to proceed their every day routine without changing their weight-reduction plan or exercise habits. Each wore a wrist device that tracked their sleep cycles, they usually weighed themselves every morning. Advanced laboratory tests teased out the difference between the variety of calories each participant ate and expended per day.
Balancing the hormones that regulate appetite
Researchers found that participants who received sleep hygiene counseling slept an hour longer each night than those that continued with their previous sleep habits. Participants who got prolonged sleep also ate a median of 270 fewer calories every day and lost a couple of pound in comparison with participants within the control group, who gained just below a pound on average.
The results are interesting, because they show the facility of education and counseling about behavior change — on this case, sleep, Dr. Frates says. He added that significant sleep time may also help people feel like they're thriving slightly than simply surviving.
But why does extra sleep matter? Sleep duration has long been linked to the body's production of appetite-regulating hormones. Insufficient sleep is related to higher levels of the hormone ghrelin, which increases appetite, and lower levels of the hormone leptin, which results in feeling less full. It predisposes people to achieve weight. Conversely, more sleep can alter these hormones and convey them back into balance.
“People can feel more alert, active, and happy with more sleep,” Dr. Frates added. “It can lead to more activity, even if it's not exercise. It can lead to sitting less and being more social.”
It's price noting that the study didn’t show whether the prolonged sleep pattern was maintained after the two-week intervention period, or what style of food the participants ate and after they ate it.
There were other limitations of the study. “Were People Making Healthier Choices in the Sleep Extension Intervention?” Dr. Frates asks. “Calories are important, but what makes up those calories is just as important. Measuring hunger levels, cravings and stress levels will also provide important information.”
Takeaway Tactics to Improve Your Sleep
A couple of key study strategies can show you how to improve how long you sleep — and potentially show you how to eat fewer calories:
- Keep a sleep record
- Monitor sleep times with wrist actigraphy devices akin to smartwatches.
- Review bedtime routines to enhance aspects affecting sleep duration.
- Limit using electronic devices a minimum of one hour before bedtime.
