5. Starving to Save Up Kilojoules

You Think: ‘I purposely haven’t eaten a thing all day so that I can let my hair down at Christmas lunch.’

The Fallout:

“This is a classic Christmas mistake,” says Gawthorne. “You are likely to be so ravenous that you serve a huge portion and then go back for seconds, which could cause a huge kilojoule blowout.”

Christmas Comeback:

» Eat three meals: Have a simple breakfast of eggs and rye toast and eat a salad for lunch. This will ensure you’re not starving with hunger and supersize your helpings at Christmas functions and then regret it the next day.

» Go for vegies first: “Serve a stack of salad and vegetables (at least half your plate) first then serve the other foods,” Gawthorne suggests. “The more vegies you eat, the more nutrients and fibre you enjoy and the less likely you will be to overindulge in other foods. It will also help portion control the other high-kilojoule foods because you will only have a little room for them on your plate.”

» Choose a smaller plate: Put a larger plate underneath it so it has the illusion of looking even bigger. When you serve your meal, you will feel that you are eating a huge feast even though you are not overdoing your intake of kilojoules.

» Pick three favourites: Rather than go for everything from the roast potatoes and gravy to the crackling, pick three favourite high-kilojoule foods to really savour in small portions. Then fill the rest of your plate with super-healthy salads and vegetables.
