My immediate family is super supportive. My brother, mom and dad are all on low-carb. We all live in different households and cities, but we keep in touch throw texts, emails, etc. My brother is actually on this forum too. But when we get together for the holidays (immediate and extended family), the people not on LC want to eat our food! It's funny and now we cook enough for everyone (faux-tatoes, LC pumpkin pie, etc.).
My friends are completely different from my family...rarely do they ask me if I can eat "there." I will have to tell them, I want to go to dinner with you, but it'll be hard for me to eat there. They'll usually say, OK, where can you eat, and I'll offer a suggestion. But they do NOT like the high fat - they're all low-fat fans. When I first did LC and the fat melted off, they were the ones saying somewhat negatives things to me. Then when I gained it all back, no one said anything (to my face anyway). But now, I'm back on LC and I feel great. I have to do what's best for me.
Also, it surprises me how many people don't even know what a carb is. My cousin who is in school for her MBA offered me some of her pie the other day and I said, no thanks, I'm on LC. She said, I don't know what a carb is. Oh my goodness...
So, basically, I get my support from my family and the forum.
