I haven’t changed anything… so why am I gaining weight?

April 13, 2026

A woman said something to me recently that I hear more and more often in clinic.

“I honestly do not understand what is happening to my body. I have not changed how I eat, I exercise more than ever, and yet the weight just keeps creeping up.”

She looked genuinely confused, and to be honest I understand why.

For most of her adult life she had been able to maintain her weight with a balanced diet and regular exercise. She was doing all the things that conventional advice recommends. And yet over the past couple of years something had clearly shifted.

Her sleep had become lighter and more disrupted. Her patience was shorter than it used to be. Her energy felt unpredictable. And the weight she was gaining was not distributed in the way it had been before. It was settling firmly around her middle.

What frustrated her most was that people kept implying the solution was simply more discipline.

Eat less.
Exercise more.
Try harder.

But the truth is that what she was experiencing had very little to do with discipline and everything to do with biology.

The transition most women are never prepared for

Most women have heard about menopause and understand that it tends to occur somewhere around the age of fifty.

What many women are never told is that the transition into menopause often begins much earlier.

Perimenopause can begin in the early forties and sometimes even in the late thirties. It can last for many years, and during this time hormones do not simply decline in a smooth predictable way. Instead they fluctuate in complex patterns.

Progesterone tends to fall first.
Estrogen rises and drops unpredictably.
Stress hormones become more reactive.
Blood sugar regulation becomes more fragile.

The result is that many women feel as if their body has suddenly changed the rules.

The strategies that worked perfectly well for twenty years suddenly stop working. Weight begins to accumulate around the abdomen. Sleep becomes lighter. Stress tolerance declines.

Over the past nineteen years working in functional medicine I have seen this pattern repeatedly. Women arrive feeling confused and often frustrated because they are doing everything they have always been told is healthy. They are exercising, eating well, and trying to manage busy lives, yet their bodies seem to be responding very differently.

Once we start to look more closely at hormones, sleep, stress, and metabolism, the picture usually becomes much clearer. What appears mysterious at first often has very real biological explanations.

This is a longevity conversation

What is happening during perimenopause has implications far beyond weight.

This transition influences metabolic health, cardiovascular risk, brain function, and long term resilience.

In other words, this stage of life is not simply about managing symptoms. It is about protecting our healthspan, the years in which we remain strong, mentally sharp, and full of energy.

This is exactly what we will explore in our upcoming free talk.

Weight Gain in Perimenopause and Menopause

If you have felt as though your body has quietly changed the rules, you are not imagining it.

Understanding what is happening hormonally can be incredibly empowering because it allows you to work with your body rather than constantly fighting against it.

In this free talk I will explain why weight gain occurs during perimenopause and what you can do to support your metabolism, sleep, and long term health.

By the end of the session you will understand:

• why abdominal weight gain often appears during the forties
• why the strategies that worked in your thirties suddenly stop working
• how hormones influence metabolism, sleep, and cravings
• the key lifestyle shifts that help restore metabolic balance

A few small shifts that can make a meaningful difference

Although we will explore this in more detail during the talk, there are several simple strategies that can make a real difference during perimenopause.

One of the most important is maintaining muscle. From the age of forty we naturally begin to lose muscle unless we actively train it. Muscle plays a central role in regulating blood sugar and metabolism, so strength training two or three times each week can dramatically improve metabolic resilience.

Another key area is blood sugar balance. Hormonal changes during perimenopause can increase insulin resistance, which means that even small fluctuations in diet and lifestyle can have a bigger impact. Ensuring meals contain adequate protein, taking a short walk after eating, and avoiding late evening snacking can help stabilise this process.

Sleep is another critical piece of the puzzle. Poor sleep raises cortisol and increases cravings, making weight regulation much more difficult. One simple strategy many women find helpful is replacing evening alcohol with a calming drink that supports relaxation and sleep.

Here is one that I particularly enjoy.

Evening Calm Mocktail

A simple alcohol free drink that supports relaxation.

Ingredients

1 cup sparkling water
1 tablespoon tart cherry juice
Juice of half a lime
A pinch of magnesium powder if you have it
Fresh raspberries
Mint leaves

Method

Add the tart cherry juice and lime to a glass and top with sparkling water. Stir in the magnesium powder and finish with raspberries and mint. It feels indulgent while helping signal to the body that it is time to wind down.

Perimenopause can feel confusing, particularly when the advice women receive does not reflect what is actually happening physiologically.

But once we understand the biology behind these changes, we can begin working with the body rather than constantly fighting against it.

If you would like to understand what is happening during this transition and how to support your metabolism and long term health, I would love you to join us.

PS: If you know a friend who is feeling frustrated by midlife weight gain, please feel free to share this with her. Many women are never told what is actually happening during perimenopause.

Let us introduce the speakers for this event

Marisa Matos BSc (Microbiology & Genetics), DipNT, mANP, mGNC

Marisa is a passionate advocate for women's health and empowerment. She is driven by an insatiable curiosity about the secrets to living a vibrant, healthy and fulfilling life.

With a background in Microbiology and Genetics, combined with extensive training in Naturopathic Nutrition, she brings a unique blend of scientific expertise and holistic wellness to her practice. After founding Ultivita Health and specialising in complex chronic illnesses, Marisa identified a significant gap in understanding among individuals regarding their bodies' functioning and the prevention of illness. She observed that many people, particularly females, lacked comprehension of their hormonal dynamics, often perceiving hormones as a nuisance rather than a vital aspect of well-being. Driven by this realisation, Marisa has made it her mission to bridge this gap by educating and empowering women to harness the power of their hormones for optimal health and vitality. Her approach emphasises the importance of metabolic health and focuses on optimising hormonal balance and bio-synchrony to transform both personal and professional fulfilment during every stage of life.

In addition to her clinical work, Marisa serves as a lecturer in Nutrition Science and contributes as a freelance nutrition writer.
