Is it really possible to lose weight overnight? If it is, it's a dieter's dream come true. Who wouldn't want to go to bed and wake up two pounds thinner? According to Caroline Apovian, M.D, author of The Overnight Diet, that's exactly what will happen if you buy her book and follow her plan. In fact, she says that you can lose up to nine pounds per week on her plan. But can weight loss really be that simple?

How the Overnight Diet Works

According to The Overnight Diet plan, getting a good night's sleep can curb hunger hormones and help you lose weight. In fact, Dr. Apovian says that following her 2-part eating plan and getting a full 8 hours of sleep each night will put your body into a fat-burning mode so that you can lose "up to 2 pounds overnight and up to 9 pounds the first week, and every week thereafter."  

But, in order to understand why this diet works, you need to dig a little deeper and look past the bold headlines. In the small print, you'll see that the weight loss plan isn't really just about sleeping more. It's about changing what and how you eat.

On The Overnight Diet, you restrict calories by fasting one day each week. On this "Power Up" day you avoid solid food and only drink weight loss smoothies. Then on the next six "Fuel Up" days, you stick to a diet of lean protein, fruits, and vegetables. You don't count calories, measure points or restrict portion sizes.

As a key part of the diet plan, you are required to get a full 8-hour sleep each night. According to Dr. Apovian, a solid night of restful sleep will curb hunger hormones, help you stick to your eating plan, and boost your weight loss potential.

Does Sleep Promote Weight Loss?

Is it really possible to lose weight overnight with a good 8-hour sleep? Some researchers believe that getting more sleep may help you eat less and lose weight. But scientists haven't been able to prove that getting more sleep causes weight loss to happen.

Studies have shown that our bodies release a hunger hormone called ghrelin when we don't get enough sleep. Why does this matter? Because ghrelin interacts with the part of your brain that regulates hunger. When that happens your body starts to behave as if it needs more food. You get hungry, your stomach starts to grumble, and you may even conserve fat to avoid starvation.

Many experts do recommend that dieters get enough sleep. Feeling energized and well-rested may help to curb hunger hormones and promote daily movement to burn more calories. But researchers have not yet confirmed that sleep alone can improve or speed up the weight loss process. So it's important to put sleep into perspective when you're trying to lose weight.

Will You Lose Weight on the Overnight Diet?

This weight loss program may work for some dieters. But not without some hard work. Losing weight is about more than just getting a good night's sleep, even though the name of this diet implies otherwise.

If you currently eat a standard diet that includes more starchy carbohydrates, fat, and sugar, switching to this strict eating style will probably result in a calorie deficit. In fact, if you follow this plan perfectly, you're likely to cut enough calories to lose a few pounds per week. And the foods you eat may be more healthy than the high-sugar, higher fat foods you currently consume.

But the plan may be too hard for many dieters to stick to over the long-term. And if your expectation is to lose 9 pounds per week, you may get frustrated and quit. No healthy diet is likely to produce that amount of fat loss especially for a long period of time. Experts generally agree that a reasonable rate of weight loss is 1-2 pounds per week.

So should you try The Overnight Diet? That decision is up to you. Getting a good night's sleep and eating a diet full of healthy lean protein, fruits and vegetables is a smart plan. But you don't have to buy a book to make those changes in your life. You'll find free information about hunger hormones, sleeping for weight loss and eating more protein online.
