It's a eally tricky time of year with Christmas coming along and it's a time when people can go completely off track, especiialy if you're really close to goal.
My advice would be to get to goal before you start to reintroduce food. I've been lurking around here for over two years and I've lost count of the amount of people who say 'i'll lose the lat bit on RTM' and then come back a month later and say 'i'd wish i'd got to goal on abstinence'. You will inevitably put on a little bit of weight through RTM but it should end up that you're about what you finished abstinence at. It's a really tricky time and very easy to try to adapt the options to suit you.
The best thing? stick to what works. Get to goal and then do RTM. That's only my opinion I know but trust me, losing weight is the easy part. It's keeping it off that is the hard bit. And for me, it doesn't get any easier but the motivation to never end up the way I was gets me through being offered scrummy things I know I can't have because if I start, I won't stop!
Make the best decision for you!
