Barbara - Well it's nice to know that my current eating habits reflect the average maintainer!

Most of my carbs are whole grains, fruits, and veggies too. I'm still working my way toward a whole foods diet.
Anne - I am like you, I don't have "carb crashes." My grams of protein have been between 50 and 84 for the past week I've been tracking, but on the other hand, I have had a good bit more meat than usual this week.
Megan - I have so been there with the fat being too low! I used to average 10% fat at most. I'm pretty comfortable with the amount of fat I'm getting right now. The amount reflected in my numbers is actually a little high for this week since I ate so much crap this weekend.
My problem lately, which inspired my post, is that I have been way too hungry. I know it's partially that I didn't plan 1000 calories for before 5pm, but I feel like something else is going on too. The few days this week where I had something with meat in it for lunch I felt much fuller during the afternoon (OTOH, the meat dishes had more cals too). I eat a very high-fiber diet so I don't think that's the issue.
I think my ideal ratio would be 20/20/60 (with 60 being the carbs). That seems like it would be enough protein to keep me fuller, enough fat to keep me healthy, and enough carbs that I could actually stand to eat my food. The fact is . . . I don't like protein all that much.

We're also trying to cut down on how much meat we eat for various reasons -- DH is concerned about his cholesterol, I'm concerned about the humane treatment of the animals, humanely treated animal meats cost waaaay more than supermarket meat, we're trying to cut our grocery budget....
And my digestive system doesn't handle beans all that well. So I usually get most of my protein from dairy and grains. I just can't imagine eating any more meat or dairy than I already do, which is where I'm struggling.
