Society has conditioned us, as women, to feel insecure about our weight, our bodies, etc., and as women we unwittingly sort of get assigned to roles in our friendships (much like that in a family dynamic). There's the hot one, the fat one, the funny one, the slutty one, the prude, the responsible one, the flake, etc. I've lost a lot of weight over the past two years and my doing so has significantly upset the delicate balance in my friendship relationships, as well as my family dynamic. We still haven't figured out where I fit into things yet and there are still awkward moments. My guess is that your friends aren't intentionally trying to be mean. If anything, your weight loss is so LOUD in their own heads that they aren't even thinking about you at all - they are, instead, thinking of their own insecurities, failures, etc. Their interrupting you and being rude is probably on a subconscious level. If they have been good friends, it may just take some time for you all to sort out where you fit into the social order of your group. Because, believe me, it's not just your new body they are noticing. It's also your new confidence that is a natural byproduct of losing weight and feeling great about it. Give them some time to get used to the new you. If they are true friends, it will sort itself out.
