Ok here it goes....
What seems like a basic question to most is quite complex to me. Most say that carbs are essential to fuel muscle...but from what i have studied this is a gross oversimplification that is starting to get on my nerves.
ATP fuels muscles not glycogen. Glycogen is a stored energy source that is broken down into ATP via glycolysis -> Krebs -> Electron Transport chain.
Glycogen is first broken down into glucose, converted into 2 pyruvate. In the presence of oxygen it will then be converted to acetyl CoA and in an anaerobic environment will be converted to lactic acid (like when u work out).
But lets go with the anaerobic process from acetyl CoA its further reduced until it hits the ETP(electron transport chain) as CO2, NADH, and FADH2. The net output about 34-36 ATP.
Now lets go back to the conversion of pyruvate to Acetyl CoA. Fat can be oxidized to fatty acids down to acetyl CoA and then can undergo the Krebs cycle and the ETP which produces a bulk of the 34-36 ATP. Glycolysis only yields a net ATP output of 4 ATP.
Lets take this even further in the process known as gluconeogenesis where glucose is made from pyruvate which can be derived from high levels of acetyl Coa which are converted to pyruvate so and then made into glucose to then be stored as glycogen.
So after a gross over simplification of the pathways i pose the question...why are carbs needed in diets? What are the downfalls of ketosis? Are there actually any documented studies attributed to what happens with prolonged lack of carbs? Will the lack of carbs lead to muscle atrophy if levels of fat and protein intake are sufficient (maintenance or above)?
Also if carbs are needed how much do u actually need in order to avoid possible negs of low carbs? How is carb cycling more efficient at created fat loss/muscle gain? What is the ideal period to cycle? How long should one carb cycle? etc.
Im sick and tired of over simplified answers, bull**** opinions, biases due to promoting some new diet fad to have u spend **** tons of money on their books and products and i want to get down to the science of the matter.
So to my educated peers and superiors on Anabolic Minds....please help. I really want to have some intellectual debate on this matter. I dont want this to be offensive or spark conflict....i just to start getting into the "meat and potatoes" of dieting 101
