The author of a new RSC book on the science behind obesity is urging Christmas diners to stack their festive plates high with food.
But, says Dr Claire Allardyce, their eyes should feast on the plate's contents before the fork is lifted.
Scientist Dr Claire Allardyce, writer of Fat Chemistry said today: "The mind has a powerful influence over what we think we have eaten and how satisfied we become.
"Recent research suggests that our memory of a meal is important in determining how full we feel. If our memory is of holding back or half-filling our plates, we are likely to be more hungry in the short-term than if we remember eating our fill."
"Load up your plate, but stick to single servings: When it comes to food maths, the brain has an annoying habit of forgetting second and subsequent servings. If you visualize your whole meal on a plate - take time to look at it in detail - you can help your supercomputer take stock of what you ate.
"And the despondence of depriving yourself of that once-a-year treat may do more harm than good."
Dr Allardyce added: Christmas has been a dieters' nightmare for decades because of the well-known high calorie content of roast spuds, Christmas pudding and the dreaded cheese board, not to forget the more welcome alcoholic accompaniments.
"Christmas may be the one time of year your body gets a good feed. Focus on filling up your plate with vegetables and forget about the calories in your favorite indulgences."
"Enjoying food with family and friends gives a feel-good factor as powerful against weight gain as some of the pills and potions sold over the counter."
But what about the calories? Can we really throw caution to the wind?
Dr Allardyce suggests that we can - if we follow some simple guidelines.
Start with a salad
Studies show a low-calorie salad starter dramatically reduces how much volunteers ate during their main course. On the other hand an energy-dense appetizer - those cheese stuffed potato skins, for example - has the opposite effect.
Be traditional with turkey
Don't be shy with the vegetables
Think about condiments
Accompany the meal with a high calcium mineral
