I'm not bothered by it all. If asked, I usually just say that I'm on a diet or whatever. I don't elaborate unless asked, in which case I say I'm doing a Palaeolithic diet, without mentioning I'm raw. Most people who know me well, know I'm rawpalaeo, though.
I am a little on the heavy side so it is easy for me to say I am on a diet. Instead of saying raw meat, I say I eat a lot of steak tartare because I love it (which I do) and practice usually once a day eating so I tell people I don't eat lunch to save money and also to keep from lunch food coma
on the weekends I eat what I want... I am planning on doing this my whole life and being Indian there is just too much cooked food around...
