Ok, since you tripled down.
Can you point to a formula that would consistently and accurately predict my caloric expenditure solely based on mass and distance?
I dispute your assertion that biological differences do not play into it. Ever notice how hard a fat person has to work in the heat? The increased respiration and heart rate to cool the body come at a cost.
