A full English breakfast will be eaten by more than one in 10 on Christmas morning, while 14 per cent will instead choose a bacon sandwich.
The average fried breakfast contains around 1,200 calories, and a bacon sandwich with brown sauce can contain more than half an adult's recommended daily salt allowance.
Almost three quarters of those surveyed said they eat a traditional turkey dinner on 25 December. The typical Christmas meal, including trimmings, adds up to 660 calories.
