From Dr. Joseph Mercola:
If you are experiencing any of the following symptoms, 
chances are very good that the excess carbohydrates in your body are, in part or whole, to blame:
Excess weight
Fatigue and frequent sleepiness
Depression
Brain fogginess
Bloating (not to be confused with blogging)
Low blood sugar
High blood pressure
High triglycerides
We all need a certain amount of carbohydrates, of course, but, through our addiction to grains, potatoes, sweets and other starchy and sugary foods, we are consuming far too many. The body's storage capacity for carbohydrates is quite limited, though, so here's what happens to all the excess: they are converted, via insulin, into fat and stored in the adipose, or fatty, tissue.
