Menopause and weight gain: What the scales don’t tell you.

Have you noticed your jeans fitting differently, even though the number on the scales hasn’t really changed?

Perhaps your waist feels a little thicker, your clothes are tighter around the middle, or you don’t feel quite as strong as you used to.

And yet, when you step on the scales, the number looks much the same.

So what’s going on?

Often, the scales are simply missing part of the story.

Key Takeaways: Menopause and Weight Gain

• Menopause can change your body composition without changing the number on the scales. In one large study, the rate of fat gain roughly doubled during the menopause transition while muscle declined, yet overall weight didn’t increase any faster.
• Much of that extra fat tends to settle around the middle, so your waistline often shows the change before the scales do.
• Waist measurements are a helpful guide, not a verdict. Measure at the same time of day, every couple of weeks, and look at the trend rather than a single reading.
• Strength training helps build and protect muscle at any age. It isn’t a quick fix for weight loss, but it supports your strength, balance and independence.
• Food and movement work best together: nourishing meals through the day and regular strength work, tailored to you.
• In the study, these changes levelled off around two years after the final period, so it isn’t necessarily a process that continues indefinitely.

What the scales can’t see

Researchers followed more than 1,200 women for around 18 years, using body scans that could measure fat and muscle separately.

As the women went through the menopause transition, the rate at which they gained fat roughly doubled, while muscle began to decline.

But their overall body weight didn’t increase any faster.

This means you can gain fat and lose muscle at the same time, without seeing much change on the scales.

And for many women, that extra fat tends to settle around the middle. So it’s often your waistline, rather than the scales, where you notice the change first.

There’s some reassuring news too. In this study, these changes levelled off at around two years after the final period. So it’s not necessarily a process that continues indefinitely.

Why your waist can tell you more

Your waist measurement gives us some information about the fat stored around your middle. The Heart Foundation uses waist circumference as one simple way of assessing health risk.

For women, a waist measurement over 80cm is associated with increased health risk, while 88cm or more is associated with substantially increased risk.

These numbers are useful guidelines, not a verdict. They don’t apply equally to everyone, and waist measurements are less accurate as a risk measure for some groups, including Aboriginal and Torres Strait Islander, South Asian, Chinese and Japanese adults.

A tape measure can’t tell you everything about your health. If you’re concerned about your waist measurement or other changes you’re noticing, your GP can help put things into context.

 

What about bloating?

There’s another reason your waist measurement can change from one day to the next: digestion.

Bloating can make quite a noticeable difference to your waist measurement. A measurement after a large meal or at the end of a particularly bloated day can look very different from one taken first thing in the morning.

That’s another reason I prefer looking at the trend rather than getting caught up in daily numbers.

Same time. Same place. Every couple of weeks.

And if bloating is something you experience regularly, it’s worth paying attention to in its own right. It’s not something you simply have to put up with, and there are often things we can do to help.

When should I Start Strength Training?

Building and maintaining muscle becomes particularly important as we get older, but it’s something worth working on at any age.

One review looked at 745 women, with an average age of around 66, and found that resistance training increased muscle mass. The women trained, on average, around three times a week for about four months.

Interestingly, the review didn’t find a clear reduction in body fat.

And that’s worth knowing because strength training isn’t a quick fix for weight loss.

What it does do is help protect and rebuild the muscle that supports your strength, balance, mobility and independence as you get older.

Resistance training simply means making your muscles work against some form of resistance. That might be weights, resistance bands, gym equipment or even your own body weight.

It doesn’t have to be complicated, and you don’t need to spend hours in the gym.

Walking is fantastic too. But walking and strength training do different things, so ideally we want both.

Does Diet Matter when I’m Trying to Build Muscle?

Your muscles also need good nourishment to repair and grow.

That includes getting enough protein across the day. Depending on your individual needs, this might come from foods such as eggs, Greek yoghurt, legumes, fish, chicken, tofu or other protein-rich foods.

Exactly how much you need depends on you and your circumstances.

But food alone won’t build muscle. And doing resistance training without giving your body the nourishment it needs isn’t going to get you very far either.

This is one of the reasons I like to look at food and movement together rather than treating them as separate pieces of the puzzle.

Changes I see to Waist Circumference in Practice

There’s a pattern I see quite often in my practice.

Many of my clients who follow the Metabolic Balance program find that their waist measurement comes down.

Of course, everyone’s results are different, and I wouldn’t promise a particular outcome. But I think one of the things that can make a difference is having some structure around food.

You know what to eat, in what proportions and how much, with guidelines around when to eat. Your plan is based on your own health history, blood results, food preferences and goals.

That can take away a lot of the second-guessing.

Instead of wondering whether you should be eating more protein, cutting out carbohydrates, skipping breakfast or trying whatever you’ve just read about online, you have a clear framework to work with.

And when you’re busy, tired and already juggling plenty, that clarity can make a real difference.

It makes it easier to be consistent.

And consistency, over time, is what helps create change.

There are wins the scales will never show you

Your waist measurement is just one measure. There are plenty of other changes that matter too.

Maybe:

• your clothes are fitting more comfortably
• your energy is steadier through the afternoon
• you’re finding it easier to get up from the floor
• climbing the stairs or carrying the shopping feels easier
• you’re sleeping better
• your digestion feels calmer
• you feel stronger and more capable in everyday life

These changes don’t always show up on the scales.

So if the number hasn’t changed but your body feels different, you’re not imagining it.

There may be more going on than that one number can tell you.

FAQs

Why do I gain weight around my middle during menopause?

Changing hormones, particularly falling oestrogen, are thought to influence where your body stores fat, and it often shifts towards the middle. At the same time, muscle tends to decline, which can change your shape even when the scales stay much the same. Sleep, stress and activity levels can also play a part.

Can I gain fat without the number on the scales changing?

Yes. In a large study that followed women through menopause using body scans, fat gain roughly doubled and muscle declined, while overall weight didn’t increase any faster. This is why the scales can miss what’s happening.

What waist measurement is a health risk for women?

The Heart Foundation uses a waist over 80cm for women as a sign of increased health risk, and 88cm or more as substantially increased risk. These are guidelines rather than a diagnosis, and they are less accurate for some groups, including Aboriginal and Torres Strait Islander, South Asian, Chinese and Japanese adults. If you measure at your belly button, use it to track your own changes. Your GP can help put any measurement into context.

Do these changes keep going after menopause?

Not necessarily. In the study, changes in fat and muscle levelled off around two years after the final period. Everyone is different, but it isn’t always a process that continues indefinitely.

Does strength training help with menopause weight gain?

It helps build and protect muscle, which supports your strength, balance and mobility. A review of 745 women with an average age of around 66 found that resistance training increased muscle mass, but it didn’t find a clear reduction in body fat. So it’s valuable, but it isn’t a quick fix for weight loss. It’s worth doing at any age.

How much protein do I need after menopause?

It depends on you, your health, and how active you are. Spreading protein-rich foods through the day, such as eggs, Greek yoghurt, legumes, fish, chicken or tofu, is a good place to start. Protein works best alongside regular strength training, and a nutritionist can help you work out what suits you.
