Your metabolism is the rate at which your body burns calories thus it's pretty easy to understand why boosting your metabolism is the single biggest key to weight loss.
In most cases the difference between an overweight person and a thin person is their metabolism.
This is also why most diets fail to provide long term permanent weight lost results.
A starvation diet such as "The Grapefruit Diet" and "The Cabbage Soup Diet" will actually greatly slow down your metabolism as your body goes into "starvation mode" where it thinks it must hold on tight to any fat it has stored up.
It's very easy to see how this is going to be a big problem.
As soon as you stop these crazy low calorie diets (and of course you will, because no one can stick with such a diet) you will gain back all of your weight with interest because your metabolism will have slowed down so much.
Boosting Your Metabolism With A Day Off The key to keeping your metabolism high while dieting is the new concept of taking a "day off" from your diet on a regular basis.
But this is not something you can just add to any diet and have work, you must choose a diet which has this "day off" built into it's design because this concept only works in conjunction with following a specific diet on the other days of the week.
Choosing this method will allow you to lose weight without slowing down your metabolism so that finally attain permanent weight loss.
