ketogenic nutrition

What do you do when you are committed to a ketogenic health and weight-loss program and you are entertaining friends for dinner? In my close circle of friends, everyone has a different take on food. Some have, to a greater or lesser extent, embraced the low carb or keto approach to nutrition. Others avoid fats and eggs believing that this will lower their cholesterol levels. There are no vegans in our group but some favour vegetarian meals.
