Correct you're learning. Glucose, carbs, fat then protein in that order for fuel.

Don’t patronize me. Protein gets broken down faster than fat. If your body is in fight or flight like it is with athletes, they are burning muscle as soon as they run out of glucose. That’s why sports drinks have some sugar in it. And that’s why fat athletes in sports still drink a sugary sports drink.
Everything eventually gets broken down to glucose either way. Protein -> Fat -> Carbs -> Glucose.
Your body wants glucose for immediate fuel, then will convert carbs to glucose next, then will convert fat to glucose next, then will as a last resort convert protein to glucose.
