Is Your Weight Loss Plan Missing a Key Ingredient?


You've heard it said for decades now; eat right, get regular exercise, and the pounds will start to come off. But recent research shows that once again, the complexity of the human body has caught science off guard. Health (and more specifically weight management) it seems, is not just a matter of consuming the chemical cocktail you need and keeping your body moving. There is another critical factor that is all too often overlooked — getting enough sleep.

The Effects of Poor Sleep Hygiene

When you get inadequate amounts of sleep, the effects on your body are profound. Over the past two decades — during which humans in the First World have gotten less and less sleep each year — various studies have collectively shown that insufficient sleep will:

  • Inhibit your body's ability to process sugar;
  • Increase your inflammation levels, resulting in universally-increased pain response;
  • Dysregulate your endocrine system; resulting in, among several other effects, increased appetite and decreased executive function (a.k.a. "willpower").

In other words, poor sleep hygiene means you exercise less, think poorly, eat more, hurt more, and can't handle sugar. That's a recipe for dieting failure!


Sugar Processing

A 2010 study examined the sugar processing ability of 9 healthy adults after a single night of 3 hours of sleep. (Each was given 3 such nights, separated by a few weeks, for statistical averaging). The results were astounding; after just one night of sharply-reduced sleep:

  • Their bodies produced 22% more glucose than normal, however…
  • Their bodies only eliminated 80% as much glucose as normal, and…
  • Evidence showed that the sugar handling issues were a result of temporary insulin resistance brought on by lack of sleep.



A review of several studies published in 2010 revealed that acute sleep deprivation caused the inflammatory system to react as though the body had suffered an acute injury (like getting stabbed) or an acute infection (like a sudden flu). But because sleep deprivation occurs body-wide, it is like getting stabbed or infected everywhere at once. That kind of systemic inflammation makes you feel stiff, achy, and in continual pain.

Hormonal Dysregulation

The hormones dysregulated by sleep deprivation include leptin (the 'I'm hungry' hormone), ghrelin (the 'I'm full' hormone), cortisol (the 'I'm stressed' hormone), dopamine (the 'I feel good' hormone), and norepinephrine (the 'I'm in danger' hormone). Leptin, cortisol, and norepinephrine spike, while dopamine and ghrelin plummet. In other words, you can't think straight because your body is telling you it's stressed out, and you eat compulsively (compounded by the fact that you can't think straight).

Bottom line: if you want to be successful with your weight loss goals, get a good night's sleep as often as possible. If you have to change your schedule, forsake some activities, or take some melatonin supplements to do so, do it. Good sleep hygiene is just as much a part of weight management as eating well and exercise. If fail to consistently get a good night’s sleep, any efforts you make in these other areas are a waste of time!
