As we enter a new year armed with resolutions to improve our lives, there’s a good chance we’ll also be carrying something less helpful: extra kilos. At least half a kilogram, to be precise.

“Weight creep” doesn’t have to be inevitable. Here’s what’s behind this sneaky annual occurrence and some practical steps to prevent it.

Small gains add up

Adults tend to gain weight progressively as they age and typically gain an average of 0.5 to 1kg every year.

While this doesn’t seem like much each year, it amounts to 5kg over a decade. The slow-but-steady nature of weight creep is why many of us won’t notice the extra weight gained until we’re in our fifties.

Why do we gain weight?

Subtle, gradual lifestyle shifts as we progress through life and age-related biological changes cause us to gain weight. Our:

• activity levels decline. Longer work hours and family commitments can see us become more sedentary and have less time for exercise, which means we burn fewer calories
• diets worsen. With frenetic work and family schedules, we sometimes turn to pre-packaged and fast foods. These processed and discretionary foods are loaded with hidden sugars, salts and unhealthy fats. A better financial position later in life can also result in more dining out, which is associated with a higher total energy intake
• sleep decreases. Busy lives and screen use can mean we don’t get enough sleep. This disturbs our body’s energy balance, increasing our feelings of hunger, triggering cravings and decreasing our energy

• stress increases. Financial, relationship and work-related stress increases our body’s production of cortisol, triggering food cravings and promoting fat storage
• metabolism slows. Around the age of 40, our muscle mass naturally declines, and our body fat starts increasing. Muscle mass helps determine our metabolic rate, so when our muscle mass decreases, our bodies start to burn fewer calories at rest.

We also tend to gain a small amount of weight during festive periods – times filled with calorie-rich foods and drinks, when exercise and sleep are often overlooked. One study of Australian adults found participants gained 0.5 kilograms on average over the Christmas/New Year period and an average of 0.25 kilograms around Easter.

Why we need to prevent weight creep

It’s important to prevent weight creep for two key reasons:

1. Weight creep resets our body’s set point

Set-point theory suggests we each have a predetermined weight or set point. Our body works to keep our weight around this set point, adjusting our biological systems to regulate how much we eat, how we store fat and expend energy.

When we gain weight, our set point resets to the new, higher weight. Our body adapts to protect this new weight, making it challenging to lose the weight we’ve gained.

But it’s also possible to lower your set point if you lose weight gradually and with an interval weight loss approach. Specifically, losing weight in small manageable chunks you can sustain – periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight.

2. Weight creep can lead to obesity and health issues

Undetected and unmanaged weight creep can result in obesity which can increase our risk of heart disease, strokes, type 2 diabetes, osteoporosis and several types of cancers (including breast, colorectal, oesophageal, kidney, gallbladder, uterine, pancreatic and liver).

A large study examined the link between weight gain from early to middle adulthood and health outcomes later in life, following people for around 15 years. It found those who gained 2.5 to 10kg over this period had an increased incidence of type 2 diabetes, heart disease, strokes, obesity-related cancer and death compared to participants who had maintained a stable weight.

Fortunately, there are steps we can take to build lasting habits that will make weight creep a thing of the past.

7 practical steps to prevent weight creep

1. Eat from big to small

Aim to consume most of your food earlier in the day and taper your meal sizes to ensure dinner is the smallest meal you eat.

A low-calorie or small breakfast leads to increased feelings of hunger, specifically appetite for sweets, across the course of the day.

We burn the calories from a meal 2.5 times more efficiently in the morning than in the evening. So emphasising breakfast over dinner is also good for weight management.

2. Use chopsticks, a teaspoon or an oyster fork

Sit at the table for dinner and use different utensils to encourage eating more slowly.

This gives your brain time to recognise and adapt to signals from your stomach telling you you’re full.

3. Eat the full rainbow

Fill your plate with vegetables and fruits of different colours first to support eating a high-fibre, nutrient-dense diet that will keep you feeling full and satisfied.

Meals also need to be balanced and include a source of protein, wholegrain carbohydrates and healthy fat to meet our dietary needs – for example, eggs on wholegrain toast with avocado.

4. Reach for nature first

Retrain your brain to rely on nature’s treats – fresh vegetables, fruit, honey, nuts and seeds. In their natural state, these foods release the same pleasure response in the brain as ultra-processed and fast foods, helping you avoid unnecessary calories, sugar, salt and unhealthy fats.

5. Choose to move

Look for ways to incorporate incidental activity into your daily routine – such as taking the stairs instead of the lift – and boost your exercise by challenging yourself to try a new activity.

Just be sure to include variety, as doing the same activities every day often results in boredom and avoidance.

6. Prioritise sleep

Set yourself a goal of getting a minimum of seven hours of uninterrupted sleep each night, and help yourself achieve it by avoiding screens for an hour or two before bed.

7. Weigh yourself regularly

Getting into the habit of weighing yourself weekly is a guaranteed way to help avoid the kilos creeping up on us. Aim to weigh yourself on the same day, at the same time and in the same environment each week and use the best quality scales you can afford.

At this time of year many of us resolve to prioritise our health. So it is no surprise there’s a roaring trade of products purporting to guarantee you live longer, be healthier and look more youthful.

While an estimated 25% of longevity is determined by our genes, the rest is determined by what we do, day to day.

There are no quick fixes or short cuts to living longer and healthier lives, but the science is clear on the key principles. Here are five things you can do to extend your lifespan and improve your health.

1. Eat a predominantly plant-based diet

What you eat has a huge impact on your health. The evidence overwhelmingly shows eating a diet high in plant-based foods is associated with health and longevity.

If you eat more plant-based foods and less meat, processed foods, sugar and salt, you reduce your risk of a range of illnesses that shorten our lives, including heart disease and cancer.

Plant-based foods are rich in nutrients, phytochemicals, antioxidants and fibre. They’re also anti-inflammatory. All of this protects against damage to our cells as we age, which helps prevent disease.

No particular diet is right for everyone but one of the most studied and healthiest is the Mediterranean diet. It’s based on the eating patterns of people who live in countries around the Mediterranean Sea and emphases vegetables, fruits, wholegrains, legumes, nuts and seeds, fish and seafood, and olive oil.

2. Aim for a healthy weight

Another important way you can be healthier is to try and achieve a healthy weight, as obesity increases the risk of a number of health problems that shorten our lives.

Obesity puts strain on all of our body systems and has a whole myriad of physiological effects including causing inflammation and hormonal disturbances. These increase your chances of a number of diseases, including heart disease, stroke, high blood pressure, diabetes and a number of cancers.

In addition to affecting us physically, obesity is also associated with poorer psychological health. It’s linked to depression, low self-esteem and stress.

One of the biggest challenges we face in the developed world is that we live in an environment that promotes obesity. The ubiquitous marketing and the easy availability of high-calorie foods our bodies are hard-wired to crave mean it’s easy to consume too many calories.

3. Exercise regularly

We all know that exercise is good for us – the most common resolution we make this time of year is to do more exercise and to get fitter. Regular exercise protects against chronic illness, lowers your stress and improves your mental health.

While one of the ways exercising helps you is by supporting you to control your weight and lowering your body fat levels, the effects are broader and include improving your glucose (blood sugar) use, lowering your blood pressure, reducing inflammation and improving blood flow and heart function.

While it’s easy to get caught up in all of the hype about different exercise strategies, the evidence suggests that any way you can include physical activity in your day has health benefits. You don’t have to run marathons or go to the gym for hours every day. Build movement into your day in any way that you can and do things that you enjoy.

4. Don’t smoke

If you want to be healthier and live longer then don’t smoke or vape.

Smoking cigarettes affects almost every organ in the body and is associated with both a shorter and lower quality of life. There is no safe level of smoking – every cigarette increases your chances of developing a range of cancers, heart disease and diabetes.

Even if you have been smoking for years, by giving up smoking at any age you can experience health benefits almost immediately, and you can reverse many of the harmful effects of smoking.

If you’re thinking of switching to vapes as a healthy long term option, think again. The long term health effects of vaping are not fully understood and they come with their own health risks.

5. Prioritise social connection

When we talk about living healthier and longer, we tend to focus on what we do to our physical bodies. But one of the most important discoveries over the past decade has been the recognition of the importance of spiritual and psychological health.

People who are lonely and socially isolated have a much higher risk of dying early and are more likely to suffer from heart disease, stroke, dementia as well as anxiety and depression.

Although we don’t fully understand the mechanisms, it’s likely due to both behavioural and biological factors. While people who are more socially connected are more likely to engage in healthy behaviours, there also seems to be a more direct physiological effect of loneliness on the body.

So if you want to be healthier and live longer, build and maintain your connections to others.
