Fat is the preferred energy source our bodies require and the science also supports this, in any endurance event your body will only utilise carbohydrates for the first 20 minutes or so, then its on to fat afterwards,

The fact that it's the first 20 minutes then onto fat would suggest fat isn't the preferred energy source.

if you run a 3 hour marathon Honky your body will spend 2 1/2 hours burning fat, this will happen however much carbohydrate you consume. If your body has no carbohydrate it will immediately switch to burning fat. Also you are missing the bit about our evolutionary history, naturally occurring carbohydrates were extremely rare in our ancestors diets, we spent millions of years without them, they only appeared in our diets roughly 5000 years ago, refined sugars around 100 years ago.

Did they? Hunter gatherers didn't just live off hunting. And while their diets were likely much lighter on the carbs than today, it wasn't non existent. I think you've found your discrepancy.

I don't disagree with the bottom line - I've been smashing a high fat diet for years, but your reasoning, if there is any, is all over the place. Your own words admit carbs are the bodies preferred energy source, so I'm not really sure what you're arguing about or against. The ADP/ATP mechanism and glycolysis have been a basic foundation of sports science for decades - it's not a secret that they are only used for relatively short bursts of activity.

Serious farming which allowed widespread consumption of carbohydrate rich foods such as wheat and rice really only started around 10,000 years ago, Refined carbohydrate such as sugar appeared widely in modern diets around 100 years ago. Im generalising, of course there were exceptions.

Stop the semantics, i didnt state non existent, I stated extremely rare.

Stop the semantics

It's not semnatics, you've completely overlooked the "gatherer" part.

First = carbs
Second = fat.

Your words. IF carbs are first used, and by your own words, it is, it means they are the preferred source, by definition. Why can you not see the contradiction?

Because you're falling into the same trap as every other diet dickhead - trying to fit everything into a monocausal explanation.

Diet "guru" #1 - "It's not x it's y"
Diet "guru" #2 "it's not y, it's x"

How about it's both, (and likely z as well)?

Note in my article i was referring to refined carbs, not all carbs. Honky made the same mistake.

Im not sure why you think because the body uses carbs first that this means they are the preferred energy source, to my way of thinking the opposite could be true.

The word "refined" didn't appear in your earlier posts.

Because that's the definition of the word. Shocked

There's a hint in the spelling of the word itself PREfer.
