Menopause is a natural stage in life, not a medical problem. But that doesn’t mean it’s always easy. From hot flushes to brain fog, symptoms can creep in from your early 40s and continue for several years. One of the most common and frustrating changes is unexpected weight gain.
Many women notice their body shape shifting, with extra weight settling around the tummy. For some, it feels like their usual diet and lifestyle just stop working.
About 8 in 10 women in Ireland say their weight changed during the menopause years. In fact, 83% of women who have gone through menopause noticed a change in their weight, and more than half said they found it hard to keep their weight under control [1].
This guide explains why menopause can lead to weight gain, how long it might last, and what you can do about it. Whether you're in perimenopause or well into postmenopause, it’s never too late to feel more in control of your health.
Understanding menopause and its stages
Menopause doesn’t happen overnight. It’s a gradual process that unfolds over several years and is different for everyone. Knowing what to expect at each stage can help you understand the changes in your body including those that affect your weight.
Perimenopause
Perimenopause is the lead-up to menopause. It usually starts in your 40s but can begin earlier. During this time, levels of oestrogen and other hormones start to rise and fall unevenly. You might notice irregular periods, trouble sleeping, mood swings, or new symptoms like hot flushes.
Hormonal shifts in this phase can start to affect how your body stores fat, particularly around your middle. Some women gain weight without changing what they eat or how much they move. Changes in appetite, tiredness, and stress levels can all play a part too.
Menopause and postmenopause
Menopause is confirmed when you haven’t had a period for 12 months. The average age in Ireland is around 51. After this, you’re considered postmenopausal.
By now, oestrogen has dropped to a lower, steady level. This change slows your metabolism, affects how your body uses insulin, and makes it easier to gain fat and harder to keep muscle. All of this can affect your weight and your confidence [6].
Why it matters
Understanding these stages helps you see that menopause weight gain isn’t a failure on your part. It’s a mix of natural changes in hormones, muscle mass, sleep, and energy needs. But there are things you can do to take back control and we’ll cover those next [2] [3].
Perimenopause weight gain
Perimenopause is a key time for weight changes, and it often starts earlier than expected – sometimes in your late 30s or early 40s. The hormones oestrogen and progesterone start to fluctuate, and this can affect your appetite, energy levels, and fat storage.
You might notice you’re gaining weight, especially around your belly and hips, even if you haven’t changed your eating habits. That’s because falling oestrogen levels can affect how your body uses insulin, making it easier to store fat and harder to burn it.
Where the weight goes
During perimenopause, weight tends to shift from the hips and thighs to the abdomen. This change in body shape isn’t just about appearance. Carrying more fat around your middle is linked with higher risks of heart disease and type 2 diabetes.
Other factors at play
It's not just hormones. Poor sleep, increased stress, and mood changes during perimenopause can all lead to emotional eating or skipped workouts. Cortisol, the stress hormone, can also encourage fat storage around the middle. And if you’re sleeping badly, it’s harder to find the energy to exercise or make balanced food choices [4].
Why early action helps
The sooner you make small lifestyle changes, like improving your sleep, building muscle, or cutting back on alcohol, the easier it may be to manage weight long-term. You don’t have to wait until menopause to take control [2] [3].
Menopause and weight gain
Once you reach menopause, your body enters a new phase where hormone levels, especially oestrogen, remain low. These changes can make weight gain more likely and more difficult to shift. But it’s not inevitable, and it can be managed.
What’s going on in the body?
Low oestrogen levels can lead to a slower metabolism. That means your body burns fewer calories at rest than it used to. You may also notice changes in your appetite, how your body stores fat, and how much energy you have for movement. At the same time, muscle mass tends to decrease with age, which further lowers the number of calories your body needs each day.
Fat is more likely to settle around the abdomen. This kind of central weight gain is more common after menopause and is linked to insulin resistance, which can increase the risk of developing type 2 diabetes.
Other factors to consider
Alongside hormonal changes, other things can influence weight at this stage of life. These include:
- reduced physical activity
- sleep disruption
- stress or mood changes
- slower digestion
These changes can creep in gradually, making it harder to spot patterns or know when to act. But understanding how menopause affects your body gives you a head start in managing these changes [7].
Does menopause cause weight gain?
Not directly. Hormones like oestrogen do influence how your body handles fat, hunger, and energy, but lifestyle and age-related changes also play a big part. That’s why some people gain weight during menopause, and others don’t. It’s the mix of lower hormones, reduced muscle mass, poor sleep, and less movement that tends to lead to weight gain [6].
How long does menopause weight gain last?
There’s no set timeline. Weight gained during perimenopause or menopause often stays unless action is taken. Some women notice a slow build-up over several years. Without support, this can continue into postmenopause. But the good news is that change is possible at any age. Simple, consistent habits can make a real difference, especially when combined with medical guidance [2] [3].

How to lose menopause weight
Losing weight during or after menopause isn’t about dieting harder or working out more. It’s about finding a balanced, realistic approach that suits your body as it changes. With the right habits and support, it is possible to lose weight and keep it off.
Everyone’s experience of menopause is different, so what works for one person might not work for another. The key is consistency, patience, and knowing which changes will have the biggest impact.
Below are some practical strategies to help with menopause-related weight gain.
Review your diet and portion sizes
Hormonal shifts can affect how your body uses food for energy. As metabolism slows, your daily energy needs drop. That means eating the same portions as before can lead to weight gain, even if your food choices haven't changed.
Try to:
- Eat regular meals to manage hunger and blood sugar
- Avoid skipping meals, which can lead to overeating later
- Reduce portion sizes gradually and check in with hunger cues
- Choose foods high in fibre, protein, and healthy fats to stay fuller for longer
Focus on strength-building exercise
Resistance training helps preserve muscle mass, which is important for maintaining a healthy metabolism. It also supports bone health and balance, both of which decline with age.
- Include two to three sessions of strength-based activity per week
- Use resistance bands, weights, or bodyweight exercises like squats and lunges
- Walking, swimming, and cycling are great for overall health but may not be enough alone
Prioritise sleep and stress reduction
Poor sleep and high stress can raise levels of cortisol, a hormone that encourages fat storage around the middle. Lack of sleep also affects hunger hormones, making it harder to manage appetite.
To help:
- Aim for 7 to 8 hours of sleep each night
- Limit screen time before bed and try to keep a consistent sleep routine
- Use mindfulness, gentle yoga, or CBT techniques to manage stress
Monitor alcohol and sugar intake
Alcohol and sugary foods are linked to weight gain, especially around the belly. They can also affect sleep and energy, making it harder to stay active and eat well [3].
- Cut back on wine, beer, and spirits during the week
- Avoid sugary drinks and snacks where possible
- Watch for hidden sugars in processed foods
These changes don’t have to be all or nothing. Small, steady steps often work better than big overhauls [4].

Best diet for menopause and weight loss
There’s no single menopause diet that works for everyone. But making certain changes to what and how you eat can support hormonal health, reduce weight gain, and improve energy levels. A balanced diet also helps manage long-term risks linked to menopause, such as heart disease and type 2 diabetes.
This section looks at what to eat more of, what to cut back on, and which nutrients can help during this stage of life.
Foods to include in diet during menopause
- Fibre-rich foods: oats, beans, lentils, vegetables, and whole grains support digestion, balance blood sugar, and help you feel full.
- Healthy fats: nuts, seeds, olive oil, and oily fish like salmon support hormone function and heart health.
- Protein: lean meats, eggs, dairy, tofu, and legumes help maintain muscle mass and reduce cravings.
- Calcium-rich foods: yoghurt, cheese, leafy greens, and fortified plant milks support bone strength.
- Phytoestrogens: foods like soy, flaxseeds, and chickpeas may help ease some menopause symptoms by mimicking oestrogen in the body.
- Water: staying hydrated supports digestion, reduces bloating, and helps you feel more energised.
Foods to avoid with menopause weight gain
Some foods can worsen symptoms like bloating, low mood, or poor sleep. Others are more likely to cause weight gain.
- Sugary drinks and snacks: these cause quick spikes in blood sugar and are high in calories.
- Refined carbs: white bread, pasta, and pastries offer little fibre and can lead to energy crashes.
- Alcohol: can affect sleep, increase belly fat, and reduce motivation to exercise.
- Processed foods: often high in salt, sugar, and additives that affect mood and energy.
- Caffeine: may trigger hot flushes and disrupt sleep if consumed in the afternoon or evening.
You don’t have to cut out everything you enjoy. The goal is to limit how often and how much you have of these foods.
Vitamins for menopause weight gain
Certain vitamins and minerals can support your body through menopause. These can help manage tiredness, mood changes, and metabolic health.
- Vitamin D: supports bone health and immune function. Many people in Ireland are low in vitamin D, especially in winter.
- Vitamin B12: helps with energy and brain function. Deficiency can be more common after 50.
- Magnesium: can support sleep, mood, and metabolism. Also found in leafy greens, nuts, and seeds.
- Calcium: works with vitamin D to protect bones.
- Omega-3s: found in oily fish or supplements, these may support heart and brain health [2] [4] [6].
