Dr. Laura, the exercise physiologist, why she would know! She should be having you take a peek at the Kreb's Cycle:
Background: Kreb's Citric Acid Cycle
The Krebs Cycle, or Citric Acid Cycle, is a cyclical set of eight reactions that systematically break down the carbon compounds from glycolysis to carbon dioxide. The pyruvate from glycolysis has been stripped of one carbon and is transferred into the mitochondria as acetyl coenzyme A. The acetyl fragment (2C) is transferred to another carbon compound, oxalacetate, which enters the Krebs cycle. For each molecule of acetyl coenzyme A, this cycle eventually yields 2 CO2 and 1 ATP (4 CO2 and 2 ATP per glucose).
The breakdown of these carbon compounds is not the primary importance of the Kreb's cycle. The Kreb's cycle generates the reduced compounds, NADH and FADH2. Six NADH and two FADH2 are produced per molecule of glucose. These molecules carry electrons to the electron transport chain, where they are ultimately responsible for the creation of more ATP through oxidative phosphorylation. Twenty-four molecules of ATP are generated per molecule of glucose from these electron carriers in the electron transport chain. The other 12 or so ATPs are generated at the substrate level in aerobic respiration.
So now you know!

Phil,
In a previous post, somepne mentioned that even Dr. Laura was saying that it is OK to consume carbohydrates now. Just in case someone wanted to know how these carbs get burned up...I thought I would offer some insight. Sort of useless info, but I was bored, and.....

You cant exercise on a no carb diet either. since I try to cycle I try to eat carbs when I can.
I was watching a Lance Chronicles episode on OLN (Lance Armstrong)
and Lances coach Chris Carmicheal said the no carb diet was foolish for exercisers.
