Sleep Away Your Excess Weight

Sleep away your excess weight: sounds like a “dream” cure for weightloss, doesn’t it? Don’t we all wish it were that simple? It’s not, actually; there are several important things we must do to lose weight, including eating fewer calories, eating nutrient rich foods instead of empty calories, excercising more, and strength training. But as it turns out, lack of sleep may indeed be an influential factor in weight gain and in sabotaging our weight loss. Therefore, getting adequate sleep could really help our weight loss.
The reason for this appears to be linked to our hormone levels, which can become disrupted from their natural balance when we don’t get enough sleep. I first heard about this when Dr. Oz mentioned it on the Oprah show several months ago. Then, my husband gave me Dr. Oz’s book You on a Diet for Valentine’s Day, and I was able to get more detailed information on this phenomenon there. Since then, I’ve read numerous similar accounts in books, magazines, and on Web sites.
Here is what appears to happen. When we get enough sleep, our bodies produce adequate amounts of a hormone called cortisol, which controls appetite, allowing our bodies to naturally recognize when we’re hungry and when we’re full. When we don’t get sufficient sleep, our bodies do not produce enough cortisol to effectively control our waking appetites. Also associated with sleep are the two hormones ghrelin and leptin. Ghrelin, which is produced in the gastrointestinal tract, stimulates appetite, while leptin, produced in fat cells, sends a signal to the brain when we are full. When we don’t get enough sleep, it drives leptin levels down, which means we don’t feel as satisfied after we eat. Lack of sleep also causes ghrelin levels to rise, which means our appetite is stimulated, so we want more food. Even after consuming adequate amounts of food, we still feel hungry if there is too much ghrelin being produced in our bodies. So, it is easy to see that if the we have too much ghrelin and too little leptin, the stage can be set for overeating, which can lead to weight gain. Another thing about too much ghrelin is that it gives us a desire for high carbohydrate, sugary, calorie-dense foods, which are the best sources of the empty calories I mentioned earlier, and eating too much of that kind of food leaves our bodies “starving” for nutrients, which makes us even hungrier. So, it seems that inadequate sleep can set us up for a hormonal train wreck leading to tireder, fatter bodies for all of us.
That leads us to two questions: 1) How much sleep do we need to have normal hormone levels reached? and 2) How do we manage to get that amount of sleep? First of all, I read somewhere that each of us individually needs different amounts of sleep. Sleep experts say we need anywhere from 7-9 hours of sleep a night, and sleep researchers studying the sleep/weight loss connection say that there is typically only a fifteen minute difference in amounts of sleep gotten by normal weight people and overweight people. So, it seems that increasing our sleep to optimum levels might not be as big of a challenge as we might fear. That is, it’s not that big of a challenge if we’re within 15-30 minutes of our ideal sleep levels to begin with. So, we have to figure out how much sleep we really need and compare that to how much sleep we actually get. Sleep experts show that few of us actually get the minimum of seven hours, but to see how much is natural for us individually, we should find out in the following way: Sleep as long as we want for several days (best done on vacation). Then, our sleep should stabilize, and we’ll find ourselves waking up after the same number of hours daily, within 15 minutes or so. That is our optimum level that we really need. I don’t know what we do to tell how much we need if we have severe sleep problems and can’t sleep as much as we need whether on vacation or not.
I qualify as a sleep expert when it comes to knowing why certain of us don’t sleep well since I have had a history of not sleeping well and have undergone two separate sleep studies more than 10 years apart to see why. Here are some reasons we don’t sleep enough:
- Stress or anxiety
- Illness
- Noise
- Light
- An over-committed schedule
- Caffeine
- Alcohol
- Stimulant medications (such as diet pills, cold and allergy remedies, asthma medications)
- Depression or anger
- Fear
There are remedies for all of the above, and if we’re not getting enough sleep, we owe it to ourselves to try to solve these problems. I usually sleep quite well myself if I take certain precautions (see my article entitled “I Just Wanna Sleep!” in the Helpful Remedies Category) to make sure I do. But my most recent biggest obstacle to getting a good night’s sleep is voluntarily staying up too late. I naturally feel very sleepy between 10 and 10:30 every night, but if I don’t go to bed then and push past that natural sleep cue, I get a second wind and can stay up for hours past that before I get tired again. I still must wake up at the same time, though, so this causes me to have a sleep deficit. The only answer to my problem is to just stop doing it!
It’s very clear from my own experience and from a lot of things I’ve read and viewed that inadequate sleep can really sabotage a weight loss regimen, and even if we’re not on a weight loss regimen, lack of sleep can cause problems maintaining weight loss or can actually make us gain weight. It may not be as simple as just sleeping away our excess weight, but it’s all too obvious that we all need to make getting adequate sleep a part of our healthy living style. When our bodies are not hungry for sleep, maybe we won’t be so hungry for excess food either.
