Top reasons not to do this to your body include the following. 
1 1.You need Carbohydrates for normal Brain, Heart, and Muscle function.  The main fuel for the Brain and Central Nervous System is Glucose.
2 1.If Carbohydrates are unavailable the body will try to preserve valuable protein by producing Ketones made from partial burning of fatty acids.  As these build in the blood you will form a condition called Ketosis.  The Kidneys try to rid the body of these built up in your blood and you end up loosing water weight initially.
3 1.Ketosis has side effects like; headaches, bad breath, dizziness, fatigue, and nausea.  This is due to the increase acidic level of your blood.
4 1.Fat can only be metabolized through the Krebs cycle oxidation.  Low carb and no-carb diets reduce the Krebs cycle.  This also diminishes the rate of ATP production from fat metabolism.
5 1.Carbs are essential in ones ability to metabolize fat, or make free fatty acids available to produce ATP, and go toward reducing body fat.
6 1.When stored Glycogen (carbs) are used up you will experience a large weight loss due to water reduction within the cells of the body.
7 The body will burn fatty acids but will rely mainly on amino acids (protein) for energy.  Most of your weight loss at this point will be lean body tissue reduction.  This will also cause shorter time to fatigue during exercise.
 
We can make you increase lean body tissue and decrease stored fat at the same time!  Come in and see how.
