1. Avoid going to parties or functions hungry. You are much more likely to fill up on (and overeat) the nibblies (which might include chips/lollies/sausage rolls etc) rather than waiting for the main meal. Have a small snack before you go (such as a piece of fruit or a tub of yoghurt) to take the edge off your hunger.
2. Be wary of drinking your calories. Alcohol has a very high kilojoule content so if you choose to drink, try to have lower-alcohol options (such as light beer or low-alcohol wine) or have a non-alcoholic beverage between drinks.
3. Christmas is a great time to enjoy some of your favourite foods, however it is easy to go overboard with portions. If you do go for a higher-kilojoule treat, make sure it’s a food you really enjoy and make sure you are eating it because you really do want it, not just because it is there!
