Has it ever seemed like you only have two choices during the holiday season:
1. Gain weight
2. Give up all your fav foods at the holidays (or at least give up all the delicious ingredients that make holiday foods taste good -- I don't care what you say....mashed cauliflower might taste good but it isn't a even up substitution for mashed potatoes!!)
A good many of us give up our best eating intention soon after the holiday season starts. And some of us even give up before the holidays start since there really isn't any reason to put it off -- we know we won't stick to our good intentions anyway!
It really (REALLY) doesn't have to be that way! You always have more choices than just those two.
How about adopting the FOOD SNOB attitude?
Don't eat the dried out fudge, day old cookies (or gasp! the store bought cookies you can get any ol' time of the year). Don't eat the casserole you brought to the party -- you can make it for yourself some other time. Don't take the salad because you "think you should" -- like a few greens or stalks covered in dressing or dip are going to some how absolve over indulgence.
Pick the cookie that has so much butter in it you can smell it even when it's cooled. Have the real sour cream and cream cheese mashed potatoes. Don't worry about skimming every mili-ounce of fat off the top of the turkey gravy.
And when you take that bite of cookie, mashed potato, or dressing with gravy on it --- appreciate that taste. Don't shovel it in! When the taste stops making you say "WOW!! OH MY GOODNESS -- THIS IS THE BEST THING I HAVE EVER EATEN!!" stop eating.
There will be left-overs. Or another dinner in the near future. This isn't your one and only chance. Remember that it feels OH MY GOODNESS GREAT! to leave the table and still be able to tie your shoes.
