For ordinary day to day living, I find I will eat everything on the plate, and control the portion sizes I make to control my eating. Also I just don't buy a lot of sweets and finger food.
For long rides (100 to 200 miles), like you, I find that I will eat everything in sight on the day of the ride, and the day after. Those long rides are stressful on the body!!! Plus, there are benefits of mid-ride caloric boosts!!!
Go to Strava and look at the "calories burnt".
One of my longer and more intense rides, Strava estimates at 6,937 calories. And, I believe that Strava may well have underestimated. Nonetheless, that is 3x, maybe 4x my daily caloric consumption.
So, unless you are on a strict weightloss regimen... EAT SOMETHING!!!
