When you do come face to face with a buffet, or holiday food trays, be selective. Skip the foods you eat everyday, like bread and potatoes, or rice. Focus on the special dishes you wouldn't normally be offered. Another secret to moderation is to eat slowly and really enjoy the treats. If you eat rapidly, you tend to eat more.
Portion control is a key element to moderation.
The goal is to avoid eating in excess. It is important to maintain a regular exercise program during the holiday season. People get very busy during the holidays because they have to go shopping or they are busy going to all these events, but they have to remember to still make exercise a priority. Deprivation and guilt certainly are not part of the holiday spirit. Aim to maintain your current weight by eating in moderation.
