Remember, on Christmas Day, your plate can look however you want it to. Everyone should be able to enjoy whatever they want on Christmas. I think the most important thing is to make sure you’re not depriving yourself. When it comes to the actual day, I want to enjoy it – and that means, often, I do overeat. I know I am healthy most of the time, so it doesn't matter.
Instead of stressing about what you’re going to eat on Christmas Day, what I’d recommend is getting up and making sure that you get moving in the morning. Maybe you could go for a run with your family after you open the presents or play some sport in the afternoon (which I usually can’t do because I’m too full of Christmas turkey).
At the end of the day, the festive season shouldn’t leave you feeling guilty, but it also shouldn’t leave you feeling deprived. It’s all about finding the right balance for you and enjoying the break.
