Nutrition Support Groups/ Where can I meet healthy friends?

Hello! I am wondering where I can go to meet people who care about eating healthy or where can I find weight loss support groups. I suppose the gym is a place to meet people but I would not know what to say and I dont want to interrupt anyone. I think about going to healthy restaurants like Sweet Green or any vegan place but even then I wouldnt know what to say and most people arent looking to meet people when they are going to get their food quickly. Also a flaw with the gym is that some people work out but dont eat healthy because they probably think the working out makes up for it and I suppose it does but I need to just not be around junk food at all. I am like a heroin addict for junk food.
