Interestingly, one of the most important things you can do to energize your body is to give it more rest. While experts say people require different amounts of sleep, most people should get between seven and eight hours a night. A lack of sleep has been traced back to many of our worst health issues.
Note to those trying to lose weight: a lack of sleep can also have a negative effect on your diet, according to a recent study published in the Annals of Internal Medicine. Researchers tested 10 dieters by reducing their caloric intake moderately. Those who slept a full night of 8.5 hours lost more than half of their total weight loss (about 6.6 pounds) in fat. However, those who slept only 5.5 hours, lost a similar amount of weight, but less of the loss was body fat, with proteins and fat-free body mass making up a bulk of their weight loss.
The sleep deprived also had unfavorable changes in their metabolism during the study. When you don’t sleep enough, you can’t possibly keep up with life’s demands.
