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.

With one in four Australian adults experiencing problems with incontinence, some people look to supplements for relief.

With ingredients such as pumpkin seed oil and soybean extract, a range of products promise relief from frequent bathroom trips.

But do they really work? Let’s sift through the claims and see what the science says about their efficacy.

What is incontinence?

Incontinence is the involuntary loss of bladder or bowel control, leading to the unintentional leakage of urine or faeces. It can range from occasional minor leaks to a complete inability to control urination and defecation.

This condition can significantly impact daily activities and quality of life, and affects women more often than it affects men.

Some people don’t experience bladder leakage but can sometimes feel an urgent need to go to the bathroom. This is known as overactive bladder syndrome, and occurs when the muscles around the bladder tighten on their own, which greatly reduces its capacity. The result is the person feels the need to go to the bathroom much more frequently.

There are many potential causes of incontinence and overactive bladders, including menopause, pregnancy and child birth, urinary tract infections, pelvic floor disorders, and an enlarged prostate. Conditions such as diabetes, neurological disorders and certain medications (such as diuretics, sleeping pills, antidepressants and blood-pressure drugs) can also contribute.

While pelvic muscle rehabilitation and behavioural techniques for bladder retraining can be helpful, some people are interested in pharmaceutical solutions.

What’s in these products?

A number of supplements are available in Australia that include ingredients used in traditional medicine for urinary incontinence and overactive bladders. The three most common ingredients are:

• Cucurbita pepo (pumpkin seed extract)
• glycine max (soybean extract)
• an extract from the bark of the Crateva magna or nurvala (Varuna) tree.

How are they supposed to work?

Pumpkin seeds are rich in plant sterols that are thought to reduce the testosterone-related enlargement of the prostate, as well as having broader anti-inflammatory effects. The seed extracts can also contain oleic acid, which may help increase bladder capacity by relaxing the muscles around the organ.

Soybean extracts are rich in isoflavones, especially daidzen and genistein. Like olieic acid, these are thought to act on the muscles around the bladder. Because isoflavones are similar in structure to the female hormone oestrogen, soy extracts may be most beneficial for postmenopausal women who have overactive bladders.

Crateva extract is rich in lupeol- and sterol-based chemicals which have strong anti-inflammatory effects. This has benefits not just for enlarged prostates but possibly also for reducing urinary tract infections.

Do they actually work?

It’s important to note that the government has only approved these types of supplements as “listed medicines”. This means the ingredients have only been assessed for safety. The companies behind the products have not had to provide evidence they actually work.

A 2014 clinical trial examined a combined pumpkin seed and soybean extract called cucurflavone on people with overactive bladders. The 120 participants received either a placebo or a daily 1,000mg dose of the herbal mixture over a period of 12 weeks.

By the end of study, those in the cucurflavone group went to the bathroom around three fewer times per day, compared with people in the control group, who only went to the bathroom on average one fewer time each day.

In a different trial, researchers examined a combination of Crateva bark extract with herbal extracts of horsetail and Japanese evergreen spicebush, called Urox.

For the 150 participants, the Urox formulation helped participants go to the bathroom less frequently when compared with placebo treatment.

After eight weeks of treatment, participants in the placebo group were going to the bathroom to urinate 11 times per day. Those in the Urox group were only going around to 7.5 times per day. And those who took Urox also needed to go to the bathroom one fewer time during the night.

Finally, another study also examined a Creteva, horsetail and Japanese spicebush combination, but this time in children. They were given either a 420mg dose of the supplement or a placebo, and then monitored for how many times they wet the bed.

After two months of taking the supplement, slightly more than 40% of the 24 kids in the supplement group wet the bed less often.

While these results may look promising, there are considerable limitations to the studies which means the data may not be reliable. For example, the trials didn’t include enough participants to have reliable data. To conclusively provide efficacy, final-stage clinical trials require data for between 300 and 3,000 patients.

From the studies, it is also not clear whether some participants were also taking other medicines as well as the supplement. This is important, as medications can interfere with how the supplements work, potentially making them less or more effective.

What if you want to take them?

If you have incontinence or an overactive bladder, you should always discuss this with your doctor, as it may due to a serious or treatable underlying condition.

Otherwise, your GP may give you strategies or exercises to improve your bladder control, prescribe medications or devices, or refer you to a specialist.

If you do decide to take a supplement, discuss this with your doctor and local pharmacist so they can check that any product you choose will not interfere with any other medications you may be taking.
