During the holidays it's easy to be tempted to indulge. Don't sweat it. Just remember it's all about balance. If you have a high-fat meal one time, balance it with low-fat meals. I have a number of extremely healthy meals -- such as stir-frys and omelettes -- I can prepare when I need a big belly-filling meal that's extremely low in calories.

For example, I can do a huge omelette stuffed with onions, mushrooms, peppers, zucchini, and tomatoes for under 200 calories. Even adding a couple pieces of low-calorie whole wheat toast to that -- with sugar-free jam -- I'm still under 300 calories and it's a wonderful meal. And extremely healthy with lots of vegetables and fiber.
