I really appreciate everyone's response and advice. It made me realize that if I don't want to, I don't have to explain myself. I have 3FC to guide me along the way
Star2Be, my friends are very similar to yours. Most of my friends are either thin or very fit, and they like to eat a lot. They're mainly guys. I hang out with maybe 1 or 2 female friends, but it's a rare occasion. We usually go get some pizza at a place that doesn't serve the healthiest options or the dreaded taco bell. I usually end up getting a 7 layer burrito without cheese or sour cream, which is the best option I could find to fit my lifestyle. I usually open it up and eat the insides and forgo the tortilla (that actually gets my friends questioning, but I tell them some weird explanation). My friends also like for us to get together and cook. Their idea of cooking is to put cheese on almost everything (pasta, veggies, bread, etc). I try to make myself a plate before they go cheese crazy. When they ask, I usually tell them that the ingredients in the cheese didn't specify whether or not there was rennet in it. That usually gets them to change the subject. It's still tough though, I try to get us to do things as far away from food as possible. We usually end up going to the park and walking around for a few hours, which is wonderful exercise.
