Sleep better to eat less… and lighten up effortlessly
The researchers worked with a group of overweight young adults (with a body mass index over 25, therefore) who habitually slept less than 6.5 hours per night. Thanks to personalized advice on their lifestyle, these volunteers managed to increase their average sleep time by around 1.2 hours per night. The scientists found, by comparing the group of participants with a control group, that the former consumed (on average) 270 Kcal less per day.
A reduction in caloric intake necessarily beneficial for the silhouette: in their work, American researchers estimate that prolonging this good habit for 3 years could result in a weight loss of around 12 kilos.
