The Truth About Christmas Weight Gain

The Truth About Christmas Weight Gain

If you gain a few pounds over Christmas, it’s no big deal. You can just lose it in January, right? Actually, it might not be quite so simple. Research shows that festive weight gain is a significant contributor to our weight struggles. Here’s the truth about Christmas weight gain.


Studies have shown that 50-90% of the weight Americans gain over the course of their lives is gained in the last two months of the year. And on average, people do not lose the majority of that weight.

Researchers found that over the Christmas period, weight increased by a mean 1.35% and was not fully compensated for in following months.

Just because many people do tend to gain weight over the festive period does not mean it’s inevitable for you. Read on to learn more about why we tend to gain weight in winter and how best to manage your weight this Christmas.


While weight gain patterns can vary among individuals and populations, there are some common trends that have been observed in research.

Many people experience weight gain during the festive season in the last two months of the year. In America, this typically runs from Thanksgiving in late November through to Christmas and New Year celebrations, ending early January. In India, Diwali is a popular celebration in mid November which kicks off celebrations into the New Year. Despite not having traditional celebrations that start in November, the UK and Europe have seen Christmas celebrations starting earlier and earlier, largely as a result of commercial drivers encouraging us to eat more and buy more. The abundance of festive meals, treats and social gatherings can contribute to increased intake of high sugar, ultra processed and calorie dense foods during this time.

In colder winter months there is a tendency towards more sedentary behaviour. Not wanting to go out in the cold can lead to decreased physical activity levels. Additionally, the desire for comfort foods and the body’s natural inclination to store energy for warmth may contribute to increased calorie consumption.

The combination of a drop in temperature and an increase in festive celebrations can be a recipe for weight gain.


According to research, people gain an average of 1 to 2 pounds (approximately 0.5 to 1 kg) during the holiday season, which includes Christmas. While this might not sound like a significant amount, the concern is that these small weight gains can add up over the years and contribute to long-term weight gain.


The relationship between cold weather and weight gain is influenced by various factors. While some studies suggest a potential connection between cold weather and weight gain, it’s important to consider the broader context.

From a physiological perspective, cold weather can increase thermogenesis, which is the body’s process of generating heat to maintain a stable internal temperature. This process may involve burning more calories to produce heat. However, the extent of this effect and its contribution to weight loss or weight maintenance can vary among individuals.

From a psychological perspective, some people experience an increase in appetite during colder months, possibly as a result of the body’s attempt to store energy for warmth. Body fat is, after all, insulating. Comfort foods can be more appealing in colder weather.

Cold weather can also negatively affect activity levels. Some clients that we work with share with us that they feel less inclined to engage in outdoor activities or exercise during the winter, leading to a decrease in overall energy expenditure.

Winter weight gain can be influenced by various factors including festive celebrations and the impact of reduced temperature and daylight hours on lifestyle habits.

When first meeting with new clients, some will report that their weight has yo-yoed for years, gaining weight during the winter months and losing it in the warmer months. But it doesn’t have to be this way. Not everyone experiences weight gain during colder seasons. There are habits you can adopt to ensure your weight stays consistent year-round.


How long it takes to lose the weight you gained over Christmas depends on a number of factors. Firstly, the more weight you gained, the longer it will take to lose. With a nutrition and lifestyle plan designed to suit you, you can expect to lose around 2lbs / 1kg per week.

Some people struggle more than others to lose gained weight. If you feel as though losing weight is especially hard for you, here’s an article on the common causes of weight loss resistance we see in our clinic: How To Overcome Weight Loss Resistance.


The good news is, Christmas weight gain is not inevitable. You can still enjoy the festivities (including the odd mince pie) and avoid gaining weight. Here are some practical tips we have put together to help you: 10 Simple Ways To Prevent Festive Weight Gain
