if you're not doing any significant exercise.
Have you talked to your doctor(s) about your nutritional needs with the cycling? seems like their input would be worthy.
One thing to look into might be fasted exercise to train your metabolism to use fat. It's not something you should do every ride, but mixing it in may help feel fresher after 20mi (because you're training your body to burn fat)

Back about 25 years ago, 200-400 mile weeks on the bike, I was putting down 3500 calories a day. That would kill me today.
I will look into the fasted cycling, but will skip the coffee. Never acquired a taste for the juice of the bean. But I do love tea, the stronger the better, and no sugar...
