I have lost about 100 pounds and I only have about 50 more pounds to go. I hardly have any willpower. So many holiday foods lend themselves to low fat cooking, like turkey and side dishes like mashed potatoes. Green beans, tossed with lemonade concentrate and toasted almonds, makes a great side dish. Squash can be roasted in the oven with salt and pepper and maybe garlic powder coated with a little olive oil spray.
Roasted vegetables are great, like broccoli and cauliflower.
It adds thickness and some sweetness. Stuffing doesn't have to be high fat either. Omit the butter and add artichokes or thin slices of ham, carrots and mushrooms. For dessert, skip the pumpkin pie and make apple crisp. The crust is high in fat, so if you skip the desserts with crust, you have cut out some fat.
