Six festive food swaps that will help cut calories over Christmas

Whilst many of us are looking forward to winding down for Christmas, for plenty it can also be a daunting time – especially as the number on the scales starts to creep up.

Mince pies, Quality Street, mountains of stuffing and just one more pig in blanket: the festive season wouldn’t be the same without them.

But weeks of overindulgence can wreak havoc on waistlines – and morale – particularly when we fall short of the healthy reset we promised ourselves would begin in January.

In fact, most of us will consume an extra 2,410 calories every day over the Christmas period, according to the British Dietetic Association – with as many as 6,000 calories eaten on Christmas Day alone.

By the time the decorations come down, it’s not hard to have gained at least a few pounds without even really noticing.

And for some, especially those with underlying conditions like high blood pressure, or cholesterol, this festive blow out could have more serious consequences, including an increased risk of heart attack and stroke. 

‘It’s easy to let healthy habits slip around the festive period and indulge in behaviours we wouldn’t normally allow – whether that’s eating chocolate before breakfast or grazing throughout the day,’ said registered nutritionist Helen Johnston.

‘Christmas is about pleasure, tradition and generosity – not deprivation. But with a few thoughtful swaps, you can keep all the joy, boost the health benefits and cut the calories.’

Ditch the yule log and go for Christmas cake

Yule log is indulgent – but a good-quality homemade Christmas cake made with dried fruit, nuts and spices tends to contain more fibre and plant compounds per slice, says registered nutritionist Helen Johnston.

She explains that recipes which replace some refined flour with ground almonds increase protein content, while using olive oil instead of butter reduces saturated fat and improves the balance of fats.

On average, a supermarket Yule log contains around 380 calories per slice, which is nearly a fifth of a woman’s daily recommended intake.

A single slice can also contain around 35–40g of sugar and 10–12g of saturated fat, largely from cream, butter and chocolate sponge. 

Christmas cake, by comparison, derives more of its carbohydrate from dried fruit and nuts, which also contribute fibre, small amounts of protein and minerals.

Johnston says the lower fibre and protein content of Yule log means its sugars are absorbed more quickly. ‘Foods that are high in added sugar but low in fibre and protein tend to cause a faster rise in blood glucose compared with fruit- and nut-based cakes,’ she explains.

She suggests keeping portions modest and trimming back extras. ‘Serving thinner slices and skipping icing and marzipan can significantly reduce total sugar intake while still allowing the flavour of the fruit to come through,’ Johnston adds.

Upgrade your stuffing: it’s all about the chestnuts 

Chestnut stuffing contains less saturated fat and more fibre than traditional sausage stuffing, according to registered nutritionist Alexa Mullane.

A typical portion of sausage stuffing made with pork meat and breadcrumbs can contain 8–10g of saturated fat and around 280–320 calories, while a similar portion of chestnut-based stuffing is closer to 180–220 calories, with 3–4g of saturated fat.

Chestnuts are naturally lower in fat and provide around 5g of fibre per 100g serving, along with vitamin C and plant antioxidants. Mullane explains that this higher fibre content helps slow digestion compared with stuffing made primarily from processed meat and refined carbohydrates.

Health authorities have repeatedly highlighted links between processed meat and bowel cancer. 

Cancer Research UK estimates that around 13 per cent of bowel cancer cases are linked to processed meat consumption, including foods such as sausages and bacon.

Reducing intake over Christmas – by swapping sausage stuffing or pigs in blankets for alternatives such as chestnut-based sides or small portions of liver pâté – can significantly lower overall saturated fat intake, Mullane notes.

Because chestnuts have a mild natural sweetness, she adds that chestnut stuffing can also reduce reliance on sugary accompaniments, such as cranberry sauce.

Switch mince pies for lighter panettone 

‘Traditional mince pies made with dried fruit, citrus peel and spices do provide fibre and plant compounds,’ says registered nutritionist Helen Johnston. ‘However, the nutritional value depends heavily on how they’re made.’

A standard supermarket mince pie typically contains 220–250 calories, which is around 10–12 per cent of an adult’s daily recommended intake, along with 12–15g of sugar and 9–11g of fat, much of it saturated.

Fibre and protein content is usually low, often under 2g per pie, due to refined pastry and relatively small amounts of fruit.

Johnston notes that commercial versions often include additives to extend shelf life, while homemade mince pies allow greater control over sugar, fat and fruit content. ‘Making your own mincemeat increases the proportion of dried fruit and reduces added sugars,’ she explains.

Adding brandy butter increases calorie and fat intake, though Johnston says small portions can have a different effect on blood sugar.

‘Fat slows the absorption of sugar, so using a modest amount rather than a large serving helps limit sharp rises in blood glucose,’ she says.

She adds that swapping a mince pie for a slice of panettone can reduce overall calorie intake. 

A small slice of panettone, around 50g, typically contains 170–190 calories, with less fat and sugar per serving than a supermarket mince pie. Its lighter texture also makes portion size easier to manage, while still providing a sweet, fruit-based dessert.

Cut back on crisps and reach for roasted nuts instead

Roasted nuts and crisps deliver a similar salty snack experience, but differ significantly in nutritional composition, according to registered nutritionist Helen Johnston. 

A standard 30g serving of crisps contains around 150 calories, largely from refined carbohydrate and vegetable oil, with less than 1g of fibre and minimal protein.

A comparable 30g serving of mixed nuts provides a similar calorie count but typically contains 4–6g of protein, around 3g of fibre and a higher proportion of unsaturated fats, along with minerals such as magnesium and zinc. 

Johnston explains that this combination of fat, protein and fibre slows digestion, which is why nuts tend to be more filling than crisps.

Crisps are made from refined starches that digest quickly, meaning they can raise blood glucose more rapidly in some people, Johnston adds.

She cautions that not all roasted nuts are nutritionally equivalent. ‘Some shop-bought versions contain added oils, sugars or flavourings, which increases calorie density without improving nutritional value,’ she says. 

For this reason, Johnston recommends roasting raw nuts at home with a small amount of olive oil and salt to retain a simpler ingredient profile.

Cook your roasties in fat not oil 

The type of fat used to cook roast potatoes can affect both flavour and how the oil behaves at high temperatures. Extra virgin olive oil contains polyphenols and unsaturated fats, but registered nutritionist Alexa Mullane says it is less stable when heated to the very high temperatures typically used for roasting.

‘When extra virgin olive oil is exposed to prolonged high heat, it can break down more readily, which affects flavour and reduces its beneficial compounds,’ she explains. This can result in a bitter taste if the oil reaches or exceeds its smoke point.

Mullane says animal fats such as goose fat or beef dripping are more heat-stable and therefore better suited to high-temperature roasting. ‘These fats tolerate higher temperatures without degrading and are often used in smaller quantities because of their strong flavour,’ she says.

She adds that fats also contribute nutritionally. ‘They provide fat-soluble vitamins including A, D, E and K, as well as essential fatty acids, though portion size remains important,’ Mullane notes.

Adding herbs such as rosemary and garlic can enhance flavour without increasing fat or calorie content.

Swap brandy cream for brandy butter 

The choice between brandy cream and brandy butter affects both sugar and fat intake. Registered nutritionist Helen Johnston says butter-based toppings are more concentrated, which tends to limit portion size. 

‘Butter is higher in fat and more flavourful, so people generally use less compared with cream,’ she explains.

A typical 30ml serving of brandy cream contains around 60–70 calories and added sugars, along with thickeners used to stabilise the cream. 

By comparison, one tablespoon of brandy butter contains around 85–90 calories, almost entirely from fat, but is usually served in smaller quantities.

Johnston adds that fat slows the absorption of sugar when eaten alongside carbohydrate-rich desserts. 

‘Higher-fat toppings can reduce the speed at which sugar enters the bloodstream compared with lower-fat, sweetened sauces,’ she says, noting that this is a matter of portion size rather than overall health benefit.

She also cautions against over-interpreting observational findings. Recent research suggesting an association between high-fat cream consumption and lower dementia risk did not show the same link for butter, and does not establish a causal effect.

Tesco’s Finest Really Thick Brandy Cream, for example, contains 12.4g of fat per serving, but still contributes additional sugars and calories.

For those focused on calorie control, Johnston says using a small amount of butter can be a more predictable option, as a tablespoon provides around 86 calories, making portion size easier to manage.
