Christmas :48:is indeed a tough time for dieters but I doesn't need to be. Let's face it, we didn't get fat on turkey did we? And a couple of days per year is not enough to make us gain excessively. As we well know, it isn't really Christmas dinner itself, or even Christmas and Boxing Day that does the damage, it's the run up to it and the difficultly of getting back on the wagon once you've overeaten a few times.
You just need to devise a plan and stick to it I suppose. I know that when I have been in the zone, I have been enjoying being slim so much, and trying on new clothes, I didn't overeat and one year I actually managed to lose a pound over the fortnight, just by skipping roast potatoes and anything with pastry! It's all about mind over matter. Don't be afraid of Christmas, just plan it. If you want 2/3 days off, fine, enjoy it, or just put limits in for two weeks, or if you are really in the zone I cannot describe how smug you feel watching others putting on weight while you sip your tonic water. It's like you are getting ahead in the race, and banking credits while they will have to go to the gym after Christmas LOL!
Hang in there, you're doing great!
