Never go to a holiday party hungry. If our blood sugar is low we will be more tempted to eat foods that are sugary or fattening as these foods tend to raise our energy levels quickly only to crash later. Don't stop exercising. Many of us are so busy during the holidays that we tend to stop exercising because we just can't find time. Instead of skipping our exercise routine, we should just cut our workouts in half.
Some exercise is better then no exercise.
Never skip breakfast. So many of us keep late nights and tend to over eat at holiday parties. We also compensate by skipping breakfast. Breakfast is the most important meal of the day. It starts our metabolism.
