New research indicates those who lack adequate sleep tend to consume more food and do so without burning any additional calories. A different but also recent Swedish study found similar results where those who did not have proper sleep burned up to 20 percent less calories per day. In either case, weight gain is the end product. With the work more sleep less hectic lifestyles we have today coupled with the increased consumption of fast foods and sugary drinks, it's no secret why the obesity rates are skyrocketing. It's speculated that one of the reasons for weight gain is the hormones that regulate how hungry we are, when we're hungry and what kinds of foods we crave are negatively affected when we are sleep deprived. Another potential cause are the poor health decisions made when one lacks proper sleep. Lack of sleep has also been shown to be associated with other health related issues. So eat right, be healthy and ensure you remember to get proper sleep.
