Sleeping habits have a relation with the aspect of weight loss, reveals a study published in the American Journal of Clinical Nutrition. As per the study, people who did not take enough sleep were liable to have a weight gain.

The people who wanted to reduce their weight should sleep nine hours a night so as to burn their calories. A research was conducted on 30 men and women of 30 to 40 years, by Marie-Pierre St-Onge of the New York Obesity Research Center at St. Luke's-Roosevelt Hospital and her team.

All the volunteers for the experiment were recorded to have normal weight, they were made to live and eat at the centre for two nights of different weeks. On one night, they were allowed to sleep nine hours and on the other night they were allowed to sleep for four hours. During the experiment, the volunteers were made to follow a restrictive diet for four days of the week and were allowed to have food of their choice on the fifth day of the week.

The volunteers after their four hour sleep had added 300 calories in comparison to the day when they had taken nine hours sleep. The volunteers of the experiment felt lethargic and tired when they slept for 4 hours.
