Thanks for the responses.

-i do use a power meter. Beyond riding I am moving around all the time so I figure a base requirement of 1600ish (1400 for my rmr on top of every day activities and then riding). -i have a fairly high protein intake for an endurance athlete. I do a protein shake (brown rice and pea protein) after rides in addition to lean protein and eggs with almost every meal. I'm assuming I get between 75-110g a day.

I think the point about eating the same amount every day makes sense. I never really gorge after rides unless it wasover 4 or 5 hours. You're all probably right, I eat on workout days generally due to time.

For example, I have had roughly 2000 calories today and I burned 1400 during my workout and then had to rush to class, etc.

Our bodies are smart, and I'm sure the hunger is a response to hard training and my body wants the fuel to recover to. I feel like a lot of cyclists tend to underestimate their calorie needs when they're in heavy training (and conversely you have those who way over estimate...)
