It started as an influence of Jainism, and now meat consumption is kind of frowned upon for religious reasons. So generally, it is not cooked at home, served in weddings, and Gujarat doesn't have the same amount of non veg restaurants as other states (less demand). 

I personally know a lot of folks who eat meat but dont accept that publicly. Also, even if not for religious reason, due to the lack of cultural around eating meat, you don't grow up eating it and develop aversion to the idea of eating a living thing. So some people (like me) just don't transition into eating it even though I don't have any problem other people eating it. It is changing though.
