I'm probably a bad one to ask... with #1, I had terrible cravings for Whoppers with Cheese. I gave in a couple of times a week -- but not for an extra meal... and only if I'd exercised.
I think your body does ask for what it needs... but sometimes you have to think around the craving. Like, when I wanted Whoppers with Cheese, I probably did need the extra protein and calcium... but I would've done better with a soy shake or even a slice of cheese minus the mayo and extra fat on the Whopper. We also had this incredible smoothie shop near where I lived in Cary, NC when I was pregnant last time... and I would give into my craving for yogurt/fruit smoothies justifying it to myself because is was a pretty healthy alternative. Well, it would've been if I hadn't wanted the HUGE size every time I went there LOL
This time I crave peanut butter (I think it's the iron and protein) and sugar (gummi bears sound yummy, which is weird because I probably hadn't had a gummi bear since high school) ... I try to be moderate with the peanut butter, and I have started eating navel oranges. I get a big bag at Sam's Club, and I'll usually have two a day (I don't drink much juice if any, so I think this is okay for my fruit servings). They seem to fill me up and I they fulfill my body's request for vitamin C (which also helps with the absorption of iron).
Other things that fill me up ... yogurt (I'll do a lowfat custard style... never non-fat, I just don't like it... instead of icecream), apples (great fiber), baked potato (sometimes with cheese if I'm really ravenous), one piece of string cheese if I'm really feeling like I need to get into some cheese, hard boiled eggs (awesome protein and they fill you up), and I munch on butter-lite popcorn sometimes if I'm feeling desperate... I don't know... I never do very well following someone else's diet, so this may or may not be healthy to anyone else but me. I'm being a little bit more careful with snacks this time, but mostly I try not to obsess too much.
I've recently gotten to the squished stomach point where eating large meals really makes me feel sick... and for the last week or two I have just not been that hungry, so that's a really nice switch! Last time I never seemed to get to the point where I didn't want to eat LOL
