I started a thread last week titled "I didn't feel like explaining..."
Any way I was in a similar situation. I feel like you in that I don't want to explain why I'm eating differently. especially to close friends. But really I think they may not even notice as long as we do eat something. If you read my thread there are alot of good tips with ideas on what to say without saying oh I'm on atkins Diet. Several people said they felt more comfortable saying that they no longer ate white flour or sugar. Seems like friends might respond to that a little better than Saying you are on Atkins. Any way don't worry about it any more. Just pick yourself up and continue to do your low carbing and next time it should be easire for you I hope ~ good luck to you.
