In Mental Fatigue: Costs and Benefits, Boksem and Tops advance that mental fatigue results from the brain's decision to save energy:

Yet, on "Time", Dr Marcus Raichle argues that: "while the brain burns a lot of energy, any changes in brain activity and energy use during a tough mental task are minute".

(https://time.com/5400025/does-thinking-burn-calories/#:~:text=While%20the%20brain%20represents%20just,way%20the%20brain%20consumes%20energy.)

Considering these statements, if mental work does not consume large amounts of energy and mental fatigue is caused by energy investment, why does mental work cause fatigue?
