Is getting into shape your goal, this year? A switch from high fat diet not only helps weight loss but also helps in getting sound sleep, find researchers. According to the findings published in Sleep Journal, incorporating certain changes in your diet could improve sleep patterns irrespective of your weight, thus making you feel more energetic.

Previous studies talked about the link between persistent tiredness, lack of energy through the day and irregular sleep quality and obesity. The ideal solution to fight this condition is weight loss treatment.  However, there is no solid proof to establish the fact that bad dietary habits and abnormal sleep/wake patterns are linked to excessive weight.

According to the Centre for Disease Control and Prevention, an average of about 50-70 million adults in the US are victims of sleep related disorders. A vast variety of chronic health problems such as, hypertension, obesity and depression are primarily caused by poor sleep patterns resulting in impaired cognitive function.

Study: In order to determine the impact of weight fluctuations on various sleep related aspects irrespective of the body weight, researchers from the Perelman School of Medicine at the University of Pennsylvania did a study on obesity, using diet-induced obese mice.

Half mice were fed with regular chow (RC); other half were fed high-fat diet (HFD) with 3X fat content for 8 weeks.

After the 8th week, some mice were changed to a different diet for about a week, leaving the HFD-fed-mice to gain weight and RC-fed-mice to lose weight. The remaining mice continued their respective diet plans.  

Study Findings: Diets which are high in fat content lead to sleep disruption, while the same condition gets reversed if you switch the diet. It was observed that HFD-fed-mice were 30% heavier than RC-fed-mice, slept longer and slipped into frequent naps during the day. Similar body weight but different sleep/wake patterns were observed in mice that were fed RC food for one week and 9 weeks.

The sleep effects are driven primarily by diet taken in the final week, irrespective of the initial body weight.  This also implies for those people who are not obese or overweight.

Isaac Perron, lead author of this study says, "Our findings suggest body weight is a less important factor than changes in weight for regulating sleepiness. If you are overweight and often feel tired, you may not need to lose all the weight to improve sleep, but rather just beginning to lose that excess weight may improve your sleep abnormalities and wake impairments."

So, if you want to enjoy a lifestyle which is healthy and more energetic, the researchers suggest that individuals must make dietary changes in order to stay active all through the day and therefore remain fit.

According to Dr. Sigrid Veasey, a member of Penn's Center for Sleep and Circadian Neurobiology, this hypothesis could result in enhanced alertness, more energy and regular sleeping habits in humans, thanks to a healthier diet.
