Don't forget that they WANT you to eat... I had (mind the had) this one friend that was the opposite of me - I was raised as an overweight child, she was skinny, I lost the weight in my late teens, she ballooned. She always had a problem with me being on a "constant diet" (=healthy lifestyle) and organised evenings with lots of fatty foods for us. Well, we haven't talked in about 1 1/2 years now, but I saw her last weekend. I'd guess she's now twice my weight. My friends now do understand that I don't stuff myself...
