Carl and Richard suggest doing mini-ketofests in your house. Invite a few people, perhaps one who can speak on topic related to keto, serve yummy keto food and begin to build a community. Sometimes it is easier to switch when you feel as if you aren’t going to be all alone.
I myself can speak on the topic as I am a nutrition counselor and know a lot about the topic and the human body as it relates to nutrition. I cannot have my clients over for dinner in my apartment though. Here in Switzerland that would be considered weird and inappropriate. I do speak to them about the ketogenic diet when the topic comes up about eating habits.
