Through a lot of trial and error I finally discovered yesterday it takes 3 hours to get the energy from the fruit I eat before I ride. Things got so slow I could not loose weight no matter how little I ate. So now riding 10 miles twice a day it is getting better. But still 3 hours for the three pieces of fruit to kick in? Two hours or more (not sure yet) for an energy drink to kick in. My lunch that usually is protein and fat takes about 6 hours to kick in. It sure makes it a pain to plan ahead.
