Metabolism refers to the amount of calories your body burns when it is at a resting state. It enhances when you are well rested. Studies have shown that those who do not get adequate amounts of rest have metabolism that is 5% less than those who have. Hence, you will not be able to burn more calories through a good metabolism if you are not getting enough rest everyday.

4.   Boosts Workout Performance

A well rested body can easily smash an intense workout than a sleep deprived body. When you are suffering from a lack of sleep, your body directs most of its energy in maintaining your energy levels and keeping you awake. On the other hand, when you have had a good sleep the night before, your body is free of any fatigue and hence super charged to perform exercises at its peak. It automatically leads to more calorie burn and weight loss in the process.

5.   Prevents Blood Sugar Instability

Insulin is a hormone that is responsible for directing sugar from your blood to the cells of your body so that it can be used as energy. High levels of insulin increases your appetite and you feel hungrier than usual. A lack of sleep does exactly that. By making your body insulin resistant, it directs your body to store calories as fat. Hence, it prevents you from accomplishing your weight loss goals.

Did you see how the quality of your sleep is intimately tied to your health and fitness? Consistently depriving yourself from a good night’s rest will not only ruin your weight-loss efforts but it can also make your body prone to a number of health conditions.
