Researchers gathered 80 obese adults between the ages of 21 and 40 who slept less than 6.5 hours each night on a regular basis.
Participants were given a one-on-one sleep hygiene consultation. They slept in their own beds and used wearable sensors to track their sleep.
They didn’t have to adjust their food or exercise routines, and they were not counseled to do so.
Researchers recommended that participants extend their sleep by 1.2 hours per night, for a total of 8.5 hours in bed.
A urine-based test was used to determine their calorie intake and daily energy storage.
Those who got more sleep lowered their caloric consumption by 270 kcals per day on average, compared to the control group.
According to studies, this amount might result in a 26-pound weight loss over the course of three years.
This study backs up previous research that links sleep deprivation to problems with eating regulation and weight gain.
“Previous study has shown that sleep deprivation leads to increased food consumption and weight gain in the laboratory.” “We showed for the first time in a real-world situation that when sleep is extended in individuals who typically sleep fewer than 6.5 hours, objectively measured calorie intake is reduced,” Tasali said.
