The sort of rule of thumb seems to be that it takes about 1/2 hour to
digest food and transport the resultant glucose to the muscles and a

McDonalds

IIRC, Lon Haldeman (famed endurance cyclist) ate a lot of McDonalds on
his epic coast-to-coast rides. Personally, I wouldn't go near that
stuff, but it seemed to work for him.

Years ago I read a study of McDonalds meals in an article by a
dietitian. Nothing at all wrong with it at all. Providing that you are
doing heavy physical labour all day :-)

(Hard physical labour - ~400 calories/hour. Big Mac ~540 calories.
With coke and fries ~1,100)
