Understanding weight gain at menopause … and why all that exercise might not be working.

Swiss Balls & Overweight Women

It was New Year and I made a commitment to myself to lose weight. So I joined the lcoal gym. I’ve been going 4-5 times a week, but I have to admit, 4 months on, I haven’t lost any weight whatsoever – in fact my clothes are tighter and I feel swollen and bloated. My Trainer has me doing quite a lot of heavy weights and he has put me on a high protein diet, but my energy levels are at rock bottom and I just feel heavy all the time. I’ve been reading your newsletters and I’m realising that menopause may have something to do with it. I’m 50 years old, have a full time job and have two teens at home as well – I do feel busy and over-whelmed.”  [Andrea, Christchurch, New Zealand]

Whether you followed Jane Fonda’s workouts or Bill Phillip’s prescriptive ‘Body For Life’ in the 1980s or not, exercise has always entered the mind of women who want to lose weight. In the 1990’s when personal training arrived in New Zealand (I know this because I set it up for the Les Mills group), workouts moved towards an emphasis towards strength and conditioning training. As new pathways in fitness education evolved, many new Trainers arrived in gyms having been involved in higher performance sports and body-building. Studying the role of Personal Trainers in supporting lifestyle change was part of my Master’s thesis, so I got to talk to quite a few as part of my interviews – strength and conditioning for athletes was what those I interviewed knew and loved. They bought this strength and conditioning knowledge into the fitness environment. Probably without any thought to body-type and a condition called ‘oestrogen dominance’.

Working in the exercise-education environment for over 25 years and going on to educate numerous PTs throughout New Zealand, not once in my weight loss lectures did I mention ‘oestrogen dominance’ Nor, was there any mention of how, when it comes to exercise and nutrition, doing heavy weights and eating large amounts of protein to turn over muscle is not only difficult to maintain for women, but if they aren’t sleeping well and are stressed, then protein turnover and reducing insulin overnight is also problematic.  For the ageing liver, kidneys and pancreas it’s a hard job to manage all the insulin that is produced with having to eat so much food to support the energy needed for building muscle and working so hard at the gym. A high meat protein diet is also linked to changing cardiac health and the risk of coronary plaques in middle-age and older women. (Bernstein, Qi Sun et al, 2010).

For women aged 50– 65 years, weight gain is one of their major health concerns. This is understandable as obesity is one of the most common disorders globally, and its prevalence in post-menopausal women is increasing. World-wide, the prevalence of obesity has more than doubled since 1980 – not so long ago for most of us to remember.

It is well known in Type 2 diabetes research that the hormonal changes across the perimenopause substantially contribute to increased abdominal obesity which leads to additional functional and health challenges with age. If we can get on top of our weight gain in menopause, then we help to set ourselves up for a healthier ageing. I can’t emphasise this enough.

Abdominal fat is now considered to be an endocrine organ – it is responsive to hormonal influence and has the capacity to secrete adipokines. These are important regulators of appetite and satiety (fullness), energy expenditure, inflammation, blood pressure, endothelial function influence, insulin sensitivity, and energy metabolism in insulin-sensitive tissues, such as liver, muscle, and fat. Adipokines also help to regulate insulin secretion from our pancreas. Hence, increased storage of fat in fat cells can lead to inflamed fat cells, increased presence of cellulite under the skin and over time, metabolic health chaos. 

Although weight gain per se, cannot only be attributed to the menopause transition, the changes in hormonal levels make us more susceptible to the deposition of abdominal fat in many of our organs, not only just around our abdominal region and under our diaphragm. Mid-life weight loss needs a multi-dimensional approach and doing lots of exercise can exhaust women who aren’t sleeping and send them into adrenal fatigue – which can, as I’ve mentioned numerous times, increase cortisol levels causing even more metabolic chaos.

Here are some interventions for you to focus on:

  • Restful Sleep: we can add 1-2 kg a week during menopause when we can’t sleep. And we know this thanks to a Swedish study of 400 middle-aged women who recorded shortened sleep duration and weight gain. The problem is that this is what changes our health as we age – my mother included. When we lose our precious deep sleep between 2-4am, then much of this weight becomes dangerous fat that goes on our belly and under our diaphragm.  As I often say to women who are trying to exercise off their weight gain, “If you aren’t sleeping, then you aren’t losing.”  So, change your exercise to more restorative, aerobic exercise, until you sort out your sleep.
  • Manage Oestrogen Dominance: This refers to the fact that when menopause hormonal changes arrive and women don’t adjust their lifestyle to suit these changes, our fat cells turn towards storing any excess oestrogen that arrives from our diet and hormone-agents in the environment. When this happens, there is more oestrogen stored in our fat cells and this ‘dominates’ the internal environment. Then as oestrogen becomes the dominant hormone and our liver isn’t clearing excess oestrogen efficiently, the role of progesterone changes too.  It’s why liver health is important to us as we age. We clear excess oestrogens via our liver and during menopause, our liver changes in structure and function as part of our normal biological ageing of our organs. 
  • Focus on reducing insulin spikes. This means maintaining a healthy blood sugar level throughout the day. As our hormonal environment is changing during our menopause transition, our insulin production and secretion changes too. So with better control of insulin surges from our pancreas, we help to control our energy levels, moods, hot flushes and our weight. Unstable insulin production in the pancreas can create inflammatory changes in our body as we move into post-menopause. This is because when insulin production is unstable, blood levels of glucose can become too high, which can lead to Type 2 diabetes. Know that nutrition is your best medicine. As such, you need to understand that the evidence behind the Mediterranean Diet for women in menopause to manage weight has been evolving for years. This is the type of dietary approach that I take in the MyMT™ programmes. 
  • Monitor Vitamin D levels Low oestrogen levels in our skin may cause low Vitamin D levels in the body. This increases fat storage. Our skin is our largest organ and is full of oestrogen receptors. Vitamin D is a fat-soluble vitamin and is produced in the skin with the help of oestrogen. Therefore, many women are at risk of low vitamin D levels and because Vitamin D is now recognised as a hormone, low levels have an effect on other hormones in the body too. This is due to the feedback system that operates with all of our hormones. 

Vitamin D is such a powerful hormone for women to monitor in menopause because it is also implicated in melatonin production. This is our sleep hormone, and when Vitamin D levels are low, our insomnia increases and our mood hormone, serotonin, is reduced. Serotonin works with dopamine to help our mood and motivation. So, if you are on menopause-related anti-depressants, then ask your Doctor to also check your Vitamin D levels too.  Restoring Vitamin D and sleep is crucial to your ongoing health and weight. 

  • Manage your stress – In menopause and post-menopause our body doesn’t resist stress as well as it used to, so blood pressure, heart rate and temperature go up more readily when we are feeling stressed and overwhelmed as we continue our busy lives. Some stress is good for us, but the problem in our menopause transition is that too much stress (and this includes from not sleeping and/ or too much heavy exercise) increases cortisol levels leading to adrenal fatigue. Coritsol is a powerful stress hormone which works in conjunction with melatonin, your sleep hormone. Too much stress (emotionally and physically) interferes with your sleep. When you don’t sleep, your insulin levels stay high and you resist overnight fat-burning. It’s a vicious cycle as so many women exercisers discover in their frustration with not losing weight despite all the exercise. Elaine in the UK was the same and soon learnt, that sleeping all night and managing insulin levels, comes before too much heavy exercise. Her story is HERE.
