With friends and family there are two kinds: the busybodies for whom it's none of their business what you do, and then the opposite, when you are the busybody butting into their business wanting to change their diets which is none of your business. The only solution is for everybody to mind their own business. But if you're on the receiving end of busybodies, your only solution is to mind your own business when it comes to their butting in. That's supremely difficult because it's so annoying and intrusive and involves trying to set boundaries without offending people, which is often quite impossible. Good luck to you.
