I"m ravenous the day after a lot of miles. I think I could eat all day and I would still be hungry.
If I feed the hunger, I gain weight. I have to think about how much I'm eating - but generally, it's enough to just *slow down* and prepare something, eat it, and say "okay, you've eaten. Now get back to..." I also make sure it's balanced, 'cause I figure if I'm hungry it may be a missing ingredient and the hunger won't go until I feed *that* hunger.
