Wishing everyone a Merry Christmas!!
My holiday strategy since Thanksgiving has been this: I work out more often and at a higher intensity the 2 weeks prior to a holiday. I also try to watch my nutrition carefully. I work out as much as I can through the holidays. But I also allow myself what I want at special occassions. Not a pigout fest here, but I pick the things I really want and that I really enjoy and skip the rest. If I really want waffles with whipped cream at the family breakfast, that's what I have. But I skip the sugary juices and bacon, etc that isn't that big a deal to me.
Usually I can get through without a gain. Feeling deprived is the beginning of the end to me, and this avoids that completely. Hope this is helpful.
