Actually, I was reading about fad diet and suddenly I received a message in my mail "Lose 20 Pounds in 10 Days!" So I thought I should write some more on quick weight loss diet plans and how they're intended to fail miserably.

I have already written a lot on such topics and I think you should read this article because they are flawed at the grass root level! along with this article to learn exactly what's wrong with quick diets.

There are a few facts that I want to discuss before getting into the specific details of how she lost 10 pounds in 10 days and more specifically, even after losing 20 pounds, how she has more fat.

1. Temporary weight loss will never teach to anyone how to maintain her proper weight.

2. Protein shakes are an unhealthy way to trick yourself into eating fewer calories.

3. It is unlikely that any person could lose 20 pounds of fat in 10 days. A large part of this loss is water and depleted muscle mass, not fat. Now let me explain how you get more fat (and of course unhealthy) even after losing 10 to 30 pounds with a quick fad diet.

Let's assume, for an illustration, that a normally an active person with a body composition diets of 1300 calories a day and walks 10 miles, as normal one did.

With a total energy output of 2800 calories (ENERGY OUT), and a calorie intake of 1300 (ENERGY IN), the woman's daily net calorie intake will be -1500 calories. In other words, she will have burnt 1500 calories more than she ate, and she will have lost 1500 calories worth of body fat in one day.

There are 3500 calories in one pound of fat. In order to lose 20 pounds of body fat in 10 days, her net calorie intake must be -7000 calories a day, not just -1500!

So, to lose 20 pounds of fat in 10 days, She must burn 7000 more calories than she eats each day, an almost impossible task for anyone!

This means 80% of the 20 pounds she actually lost in 10 days is NOT fat! Its muscle and water. With less muscle mass, body composition of a women has gotten worse and her body fat percentage has increased, even though she weighs less.

And I bet most of the 20% real weight loss i.e. fat loss was due to Oprah's 10 miles walk so what was the fad diet good for?

And don't forget that she's going to gain back all the muscle and water mass in some time (that has happened to her no less than 10 times now) through a complicated process due to which she'll gain a couple more pounds of excess fat than she had before going on the diet!

Read this article because they are flawed at the grass root level! to learn a little about the complicated process through which body recovers from the effects of a fad diet.
