Overnight Diet Review

The Overnight Diet was created by former NASA nutrition consultant Caroline Apovian, MD. According to Apovian, the diet allows participants to lose two pounds in the first night and nine pounds in the very first week.*

This success is said to come in the way of a special formula. For the first day, participants consume nothing but smoothies in order to kick start the metabolism. Then, for the next six days, participants eat proteins in direct proportion with their weight. So, for every kilogram of body weight, the participant is to consume 1.5 grams of proteins. This is supposed to be a lean protein way of fasting. Other non-starchy foods are also able to be eaten in excess during this time.

Do Dieters Lose Weight On The Overnight Diet?

The end result with the Overnight Diet is calorie restriction and therefore calorie reduction. So, weight loss at least in the short term is a pretty sure thing.* However, after the first week, weight loss would depend on the ongoing habits of a participant. Should they continue on with their old habits though, any lost weight would likely come back in a hurry and additional weight could easily be added on.

Is The Overnight Diet Easy To Follow?

The Overnight Diet is not a diet for those who are not of strong will. The diet is very restrictive in certain areas, and where it is not restrictive is where the trouble can start. Though there is loose guidance of what should be consumed, there are foods that are able to be consumed “as much as you like.” That can make overeating very easy, which would of course hinder results.

In addition, strength training of 21 minutes per day is expected. This can be taxing for those who are not used to any significant level of fitness. Instead of breaking in slowly, they will be expected to jump right into the fire, so to speak, and execute serious fitness they may not be able to adequately perform.


The Overnight Diet book is $24.99, but all it really includes is another form of a fad diet that will only provide short-term weight loss at best. In the end, it is little more than a hybrid diet of two of the most popular fad diets on the market today: liquid diets and low-carbohydrate diets. However, as with the rest of the fad diets, the results are typically ones that do not last much longer than the length of the fad diet itself, and the Overnight Diet is therefore better left alone.
