I just tell people that I'm sensitive to grains. When I have mentioned the paleo diet to people they seem to think it's some type of detox program. Then I had to continue by saying its a lifestyle just like being a vegetarian. In all honesty, I don't feel the need to justify the way I eat or live my life in general. People are allowed to think what they want and there's nothing I can do about it. Most of my friends actually have come to me saying they want to drop some weight and they ask what I eat. They probably think I'm pretty hard core but eating paleo for me is not too different from the way I was eating before.
