Study finds a good night's sleep may make it easier to stick to exercise and diet goals - Video

People who reported getting regular, uninterrupted sleep did a better job sticking to their exercise and diet plans while trying to lose weight, according to preliminary research presented at the American Heart Association’s Epidemiology, Prevention, Lifestyle & Cardiometabolic Health Scientific Sessions 2023.

The researchers examined whether good sleep health was related to how well people adhered to the various lifestyle modifications prescribed in a 12-month weight loss program. The weight-loss program included 125 adults (average age of 50 years, 91% female, 81% white) who met criteria for overweight or obesity (body mass index of 27-44) without any medical conditions requiring medical supervision of their diet or physical activity.

Sleep habits were measured at the beginning of the program, at 6 months and at 12 months, through patient questionnaires, a sleep diary and 7-day readings from a wrist-worn device that recorded sleep, waking activity and rest. These measures were used to score each participant as “good” or “poor” on six measures of sleep: regularity; satisfaction; alertness; timing; efficiency (the percentage of time spent in bed when actually asleep); and duration. A composite sleep health score of 0-6 was calculated for each participant, with one point for each “good” measure of sleep health, with higher scores indicating better levels of sleep health.

After adjusting the sleep health scores for age, gender, race and whether or not there was a partner sharing the bed, the researchers found that better sleep health was associated with higher rates of attendance at group interval sessions, adherence to caloric intake goals and improvement in time spent performing moderate-vigorous physical activity.
