It's the holidays. Lots of people have more treats this time of year.
Do you really think you're going to get quizzed about eating more? I think you may be imagining things. I know my paranoia and imagination were pretty ramped up at the end of my drinking and in early recovery.
Do what you need to do. Eating more is common in early days, and coffee and cookies are pretty much staple items at AA meetings. That desire will die down if it isn't pre-diabetes or some other health problem.
