The more I consume during a ride, the less hungry I feel after.
Of course you may not tolerate that, but that is a separate issue.
Because
1. Excessive glucose would be counterproductive to what one would be trying to achieve metabolically on an endurance ride.
2. You'll need a lot of toilet paper or nappies to wipe the puke on long rides.
Replacing half the calories is usually a good number,
