Overnight Diet: Lose Weight While You Sleep?


Did you get a good night’s sleep last night? Well according to a new diet by obesity doctor Caroline Apovian, M.D., if you slept eight hours, you can lose 2 pounds. And if you follow her weight-loss regime—a low-carb, high-protein diet for six days and one day of smoothies—you could lose up to 9 pounds by the end of the week.

This seems too good to be true to me. As a nutritionist, I encourage consumers to be wary of any diet that touts fast weight loss.

Sure, high-protein diets can help with weight loss—simply because most people end up eating less than they were before when they restrict carbs. But in my practice, anyone who has been on this kind of diet has not been able to sustain it long-term and usually ended up gaining the weight back, and then some.

The key is not to eliminate carbs but to learn how to eat them (a.k.a. portion control) and to learn that high-fiber carbs—fruit, veggies, and 100-percent whole grains such as barley, quinoa, and oats—can help fill you up and aid in weight loss in addition to offering an array of health benefits.

I will agree with Dr. Apovian, and have read research to support it, that if you don’t get a good night’s sleep, you are more likely to eat poorly the next day. The more tired you are, the more likely you are to grab the donut or bagel and cream cheese than to think about choosing something healthy. Being tired also makes you less likely to work out in the morning or after work. But actually losing weight while you sleep—if you want to look at it that you can’t eat while sleeping, then maybe you have a point. Otherwise...

If you are down 2 pounds after a night of sleep, it's most likely water weight, and the minute you eat breakfast and consume liquids that can change. Dr. Apovian claims that this immediate loss will help motivate someone; however, I feel that this statement is rather misleading and makes it seem that sleep is the new magic bullet.

I guess one can dream that being on the Overnight Diet will lead to healthy weight loss. But in my opinion, that would be a bad dream.
