Nutritionist decodes your Christmas cravings

Your Christmas cravings decoded: Nutritionist reveals why some of us overindulge in sugar while others binge on booze – and how to have a healthier festive season

  • Nutritionist, Alice Mackintosh has revealed reasons behind Christmas cravings
  • Wanting sweets is low blood sugar and genetic predisposition to fluctuations
  • Overindulging is often down to upbringing and family tradition 
  • Craving savoury snacks can indicate a lack of protein in your diet  

Christmas is a time for indulgence, but we all have different tastes and while some won’t be able to resist the savoury snacks on offer, others will find their waistlines bulging in January after indulging in too many tipples. 

According to research by consumer genetics company 23andMe the average Brit consumes an extra 21,337 calories in December – the equivalent of 267 pigs in a blanket, 98 mince pies or 6.5 tubs of Celebrations. 

But you can beat the seasonal bulge by simply figuring out the reasons behind your Christmas cravings, according to nutritionist Alice Mackintosh.

‘All of us process food differently and have different dietary requirements, preferences and habits, but some of us do struggle more to refuse the less healthy foods, and have a tendency to overindulge,’ she explained. ‘This can be for a variety of reasons.’

Read on to find out the potential reasons behind your Christmas cravings and how to stay on top of them.

People claim to have a sweet tooth, but this is most likely down to their eating habits over the day. 

If you have eaten a sweet breakfast such as cereal and relied on coffee or tea with sugar throughout the day to keep you going, then this can lead to fluctuating blood sugar levels that make sugar cravings more powerful. A diet higher in carbs and sugar tends to drive a cycle of continuing to eat this way. 

Your personal genetics can also leave you more predisposed to blood sugar fluctuations that drive this, sometimes leading to imbalances with insulin

Family traditions go a long way to shaping your mentality as an adult, and if you come from a family that goes ‘all-out’ at Christmas and tends to enjoy over-indulging, then it’s possible this type of behaviour will follow through into adulthood



Protein at meal times helps to keep you full and satisfied and without this we tend to get hungry faster and feel like we need to eat more. This can be the case for some vegetarians or vegans, but also those relying on higher carbs diets in general

Also, if you’ve skipped a meal and are relying on snacks, or not eating proper sized meals to fill you up, then this means you can end up grazing. This grazing inevitably tends to be on less nutritious, less balanced foods that are easy, quick, convenient and can be eaten on-the-go

If you’re tired because of a lack of sleep then scientific research shows you’re more likely to crave the wrong types of food and more calories to keep energy levels up 

Hormonal changes in women at different times of the month can lead to more cravings for unhealthy foods and a tendency to overindulge. This might be to improve energy, mood or because their appetite feels stronger



Habits can be extremely hard to break. If you always indulge in a tipple at festive parties, it takes a very determined attitude to break the habit which can be all the more testing when the mulled wine is flowing.

Eat three balanced meals a day 

Missing meals because you’re worried about your waistline or ate a lot the night before can actually mean you end up eating more overall by grazing on junk. 

More sugar cravings are also common, and you may struggle to turn down that 10th deep fried canapé!

Balance meals with protein 

It will help you stay fuller for longer and stop you devouring a selection box. Prawns, chicken, eggs, smoked salmon, ham, beans or lentils should always form 25 per cent of your plate. 

Nuts and seeds are also brilliant for adding to meals to increase protein fibre, healthy fats and essential nutrients, and are super suck and easy.

Fill up on vegetable side dishes 

This will increase nutrient content and fibre in the diet which is important for energy, immunity, detoxification and skin. 

You can also fill up on super nutrient dense Christmas favourites such as red cabbage and carrots, all of which contain vitamin C, A, B vitamins, polyphenol antioxidants and magnesium rather than carb loaded roast potatoes and stuffing, or sausages and meat.

Be prepared if you suffer from intolerances 

If you’re gluten or dairy-free and struggle to stick to it over Christmas then to avoid feeling lousy, you need to be prepared. 

This can sometimes mean eating dinner before you head out to drinks parties where you aren’t able to be sure what’s in the food on offer, or telling your host ahead of time what your dietary requirements are. 

Most restaurants these days cater to all allergies of all kinds, so you just need to ring ahead and inform them. 

Spread out the parties 

If you find peer pressure is driving your consumption and overindulgence, then plan your diary so that you aren’t back-to-back and have at least one night off each week.

If you have to drink, but know you will struggle with the aftermath, then try to go for polyphenol rich red wine, spritzers or white spirits with soda and lime, rather than sweet cocktails or sugary mixers. 

Stay hydrated with water and herbal teas over the day before and after, don’t drink on an empty stomach and aim to eat plenty of folic acid the next day from colourful veggies to support your liver.

Start the day with a smoothie 

If you know you won’t be able to get goodness into your diet owing to Christmas parties or work events then try adding a smoothie into your morning regime as a super-fast way to get as much fibre and good nutrition into your body in the morning. 

Try adding kale, berries, banana, avocado (all of which can be frozen ahead of time) flaxseed, brazil nuts and oat milk.

Get to know your genetics 

All of us process food differently and have different dietary requirements, however with so much confusing information online it is often hard to work out what suits you. 

Getting more access to your genetic information and understanding what that information means, not only provides insights that can help you identify what makes you tick so that you can make informed decisions about your dietary needs, but also creates the motivation to make changes and stick to them so you can feel your best

Get creative with canapés 

They don’t just have to be deep fried, come in pastry, or be super meaty, there are tonnes of ideas for delicious yet nutritious options with seafood, vegetables and dips and often these are just as popular as the more traditional options – get creative!

Stock up on healthier sweet treats

Nut and honey bars, cacao protein bars, dark chocolate dipped Brazil Nuts and almond-meal biscuits are easy options you can pick up from most health food stores or supermarkets.
