If you’re a woman in your 40s, 50s, or 60s struggling with midlife weight gain, you’re not alone. Midlife weight loss is one of the most frustrating parts of the menopausal transition — and it can feel like no matter what you try, the weight just won’t budge.
You’re eating healthy, pushing yourself through exercise classes, maybe even fasting or trying keto… yet the scales stay stubbornly still.
At Trinity Transformation, we’ve worked with over 7000 menopausal women who faced exactly this struggle. Women who were putting in huge amounts of effort — spinning, running, HIIT classes, low-calorie diets — but were still seeing zero movement on the scales.
The good news? It’s not your fault and it’s absolutely possible to achieve midlife weight loss and drop 1-2 dress sizes (or 15-25 pounds) in just a few short months.
In this article, we’ll reveal why women start gaining weight during midlife and, most importantly, how to combat midlife weight gain so you can feel like yourself again.
Why Women Start Gaining Weight in Midlife
It’s no secret that many women gain weight during midlife. But what’s less talked about is why this happens, and it’s not simply about eating too much or moving too little.
As you enter your 40s, the body begins to experience major hormonal shifts. The production of oestrogen and progesterone (the female sex hormones) starts to decline. And these changes during the menopausal transition contribute significantly to symptoms like hot flushes, brain fog, joint pain, and yes — weight gain.
Research from the Mayo Clinic shows that the decline in oestrogen levels affects where the body stores fat. Instead of carrying weight evenly, women tend to gain weight more around the abdomen — increasing health risks like diabetes, heart disease, and obesity.
But it’s not just about oestrogen. Another huge factor is the change in how your body handles stress.
One of the biggest issues during menopause is the way cortisol (the body’s primary stress hormone) becomes dysregulated. In small bursts, cortisol is beneficial; it helps you manage short-term stress, boosts memory, and even helps release fat during physical activity like exercise.
However, if cortisol stays chronically elevated — which often happens due to ongoing work stress, family pressures, lack of sleep, and even dieting or intense exercise — it can create a perfect storm for weight gain.
Why Cortisol Is So Important
- Insulin resistance, making it easier to store fat around the belly.
- Leptin resistance, meaning you feel hungrier and crave more “comfort foods.”
- A slower thyroid function, meaning your metabolism slows down and it becomes much harder to lose weight.
We call this combination the Weight Gain Triangle, and it’s why so many menopausal women struggle with their body weight despite doing everything they can.
Adding to the challenge is the fact that many women at this life stage are also part of the “sandwich generation”, the generation caring for ageing parents while still supporting grown-up children, often alongside demanding careers. This constant stress further fuels weight gain.
It’s clear: Menopause weight gain isn’t your fault, however traditional approaches like low-calorie dieting and high-intensity exercise can actually make it worse.
How To Combat Midlife Weight Gain
Now that you understand what’s really causing midlife weight gain, let’s talk about what you can do to turn it around.
1. Focus on Strength Training Instead of Cardio
One of the most important shifts you can make is moving away from endless cardio workouts and instead focusing on strength training.
High-intensity workouts like HIIT, spinning, and bootcamps, which may have worked brilliantly in your 20s, can now spike cortisol levels too high, making weight loss harder.
Instead, low-impact strength training done just three times a week can help build muscle mass, protect bone density, and encourage fat loss without overstressing your body.
Building muscle not only tones your body but also boosts your metabolism which means you burn more calories even at rest. Even better, strength training sessions can be short and efficient. Many of our clients can even fit them into 30-minute gaps between meetings!
2. Keep Moving Gently Throughout the Day
Another key strategy is increasing your NEAT — or non-exercise activity thermogenesis — which means the calories you burn doing everyday activities.
Instead of pushing yourself through exhausting gym sessions every day, aim to stay active throughout the day with gentle movement. Simple things like getting outside for walks, using a standing desk, or taking calls while walking can significantly improve your daily calorie burn without triggering high cortisol levels.
Staying active in a low-stress way helps you lose weight and protects your health long-term.
3. Eat to Balance Hormones, Not to Starve Yourself
Nutrition is another area where many women unknowingly sabotage their results.
Crash diets, shakes, extreme fasting, and ultra-low-calorie plans can raise cortisol, disrupt your hormones even further, and make weight loss impossible.
Instead, focus on hormonally balanced eating.
This means:
- Avoiding foods that disrupt hormones, like wheat, alcohol, dairy, and sugar (we call these WADS foods).
- Eating enough calories, but not too much — finding the “just right” amount for your body.
- Prioritising protein and fibre at every meal to stay full, support muscle, and control cravings.
Think of it like using a motorised lawn mower to cut the grass instead of struggling with a pair of scissors — it’s efficient, effective, and gets better results with less stress!
“Sleep quality was poor, things would be going through my head from the day, and I would struggle to drop off to sleep. I would always wake up around 3am. I could never drop back to sleep, I had palpitations and night sweats, my mind was on the go. In just over a year with Trinity, weight wise I have lost 13kg. This is about more than weight or size though- I feel so much better in myself-energy wise, confidence wise and mentally.”

4. Prioritise Sleep, Stress Management, and Self-Care
Managing stress is just as important as managing your food and exercise. Chronic stress not only drives up cortisol but also triggers emotional eating, poor sleep, and fatigue and all of this make it harder to lose weight.
Prioritising sleep, taking time to relax, setting boundaries at work and home, and even small habits like getting outside in the morning light can all help rebalance cortisol levels and make midlife weight loss feel easier.
Hormone therapy may also be an option for some women to help manage severe menopause symptoms, but it’s important to discuss this carefully with a qualified medical professional.
But remember, what works for one woman might not work for another. Always seek tailored advice based on your unique symptoms and health history.
