A new study has found out that overweight middle-aged adults who lose weight with a protein rich diet seem to sleep better as compared to those who lose weight with normal protein quantity, as per a report dated March 27, 2016. This paper was published in the ‘American Journal of Clinical Nutrition’.

Usually, other researches focus on the effect of sleep on weight control and diet, but this research studied that effect of diet and weight loss, mainly the protein quantity on sleep, said Purdue University’s Wayne Campbell.

In this study, over 44 obese or overweight participants who consumed either higher-protein or normal protein weight loss diet. A survey was completed for rating the quality of sleep each month throughout the study. These findings showed that people who consumed that people who consumed more quantities of protein and lost weight noted an improvement in the quality of sleep after 3 to 4 months.
