a healthy way of life?
In the low carb lifestyle it isn't necessary to count calories. You can eat as much as you want - whenever you want. You still shouldn't over-stuff yourself, though. That is never a healthy way to live. Some people are metabolically resistant. In a case like this, reducing total food intake may help to stimulate or maintain consistant weight loss. Still, it's the carbohydrates - not the calories which must be kept low.

But aren't these good to take anyway? You bet...
Have you been consistantly subjected to a diet high in sugar or refined carbohydrates. Your body recognizes only one carbohydrate -- sugar. All carbohydrates you eat, except fiber, are converted into sugar. Eating a diet that's 70% carbohydrate means that most of what you eat is sugar. That type of diet is unbalanced. The purpose of a low-carb diet is to bring your body chemistry and insulin sensitivity back into balance. In order to accomplish this, you'll need to eat a diet that is unbalanced in the opposite direction of they way you've been eating all your life.
Once the weight is gone, and your blood chemistry, blood pressure, and energy levels are back in the normal range, then you may be able to start adding some more complex carbohydrates back into your diet. By eating a
