Woman pinching her waist.

Why Your Waistline Expands In Perimenopause And What To Do About It (HINT: It Isn’t “Eat Less & Move More”.)

If you’re a woman in midlife and your waistline is expanding, your energy is plummeting, and all-in-all you just don’t feel like “you”, please hear this: you are not broken. 

You’re most likely in perimenopause. 

And that very natural stage in a woman’s life coupled with a common metabolic issue, added to the constant state of stress women experience is the root cause of this troubling trio.

It boils down to biochemistry…I know, I know…*snore*. But stick with me for a hot minute.

There are thousands of metabolic chemical interactions happening in your body at any given moment. To attempt to rattle them off would be futile and take me days, so I will spare you the details. But I do want you to be aware of a few specific interactions for our discussion.

Flipping The Switch

Cool thing is you don’t need to know them in detail or even have a cursory understanding for them to be humming along doing their thing. Thankfully we don’t have to even think about all this biochemistry stuff for our amazingly smart (and resilient) bodies to work.

Whew…you can keep that off the ever-expanding “To Do List”!

Thank goodness we don’t have to understand the intricacies of electrical engineering to flip on a switch and have light. Likewise, you don’t have to understand the inner workings of human metabolism to flip on the switch for health and excess fat loss.

I’m going to compress a ton of biochemistry into this article, and I promise it will be as non-boring as possible. There are certain things we need to talk about before we talk about metabolism and how it affects our weight.

If you’re like the vast majority of midlife women I know, you’ve noticed a little more padding around your midsection and what you used to do to get rid of it isn’t working. Not in the least.

Puberty In Reverse

We pack on body fat during midlife for a few reasons and all but a small few of those reasons are hormonal in nature. Yes. You are, in fact, hormonal.

We all are.

Men, women, children…especially those of the teenaged variety. They’re the touchiest of us all because of the wild ride their hormones take as they transition from little to no sex hormones floating around to a whole lotta sex hormones floating around as they try to find their equilibrium during puberty.

The same thing happens, but in reverse, as women hit midlife.

Estrogen is the main player here, and she has three “personalities” (chemical forms). Each has a starring role at a different stage in our life.

One is more dominant during pregnancy. Another during our reproductive years. And yet another during our wisdom years after our menopause.

When we’re in our reproductive phase, the main player is estradiol and she is made in our ovaries.

When our ovaries go into retirement and are no longer interested in propagating the species, our estrogen profile switches to a more estrone-dominant lead.

Interesting fact to bring up, the reason we put on fat around our midsection as we hit midlife is that body fat produces estrone and as the ovaries start to plan their retirement party, body fat gets the nod. Our adrenals add some estrogen to the mix (all 3 variants), but all too often they’re too exhausted from fighting off the “dragons” we slay day after day to make much in the way of a contribution. 

Body fat has to make up the difference. 

More Demand, More Supply

As we switch from one estrogen leading lady (dominance) to another our cells go into a detox of sorts. As cells are coming off the dependence on estradiol and switching to estrone, which is many times less potent and much less prevalent, our cells can go through withdrawals. But they are designed for this and when all the other hormones are in sync, playing well with one another, women transition through menopause with ease.

It is when our hormonic symphony is out of tune that we have menopausal symptoms. These symptoms are not “normal”, but they are oh so common because most women arrive at perimenopause absolutely exhausted, insulin resistant, and emotionally distraught.

Here’s where the sex hormones and our metabolic hormones play a role in how and where we store our body fat.

A Woman’s Hormone Hierarchy

Just as most things Mother Nature reigns over, our hormones have a hierarchy.

As well, all things nature are not 100% cut and dry.

Image of a Woman's Hormone Hierarchy.  Oxytocin is at the top, then cortisol, then insulin and last, her sex hormones.

For the most part Oxytocin is at the top of the hormonal hierarchy due to the fact that upping our oxytocin helps optimize the other hormones listed. Cortisol takes priority over insulin and our sex hormones because what is best for the species when cortisol is on scene is survival. Survival trumps sex (reproduction) every time.

Insulin is the hormone that tells our cells to store nutrients and energy, or to shunt nutrients elsewhere. It works beautifully, until it falls off the rails.

This derailment is what is known as insulin resistance. 

In short, insulin resistance occurs when cells develop selective hearing to hormonal signals telling the cell to burn fuel for energy or to store it.

It is estimated that 88% of American adults are insulin resistant. It stems from what we eat and the fact that when following conventional wisdom, we are grazing all day long.

I’ll dive deeper into this phenomenon in this series, but for now this explanation will suffice.

Getting To The Root Of The Problem

In the case of our metabolism gone awry, the initial issues don’t seem to be related to your blood sugar levels. But this is where it all starts.

The underlying metabolism derailment shows up as high LDL, high triglycerides (TG), High Blood Pressure, an expanding waistline, crummy energy, and low protective “cholesterol” (HDL). When a few of these issues are present in a person, they are diagnosed with Metabolic Syndrome.

“Metabolic”. Here’s the first clue it is a problem caused by food…AND, the medical community even named it!

Despite the name, you come out of the doc’s office, scripts in hand . . . a statin for the cholesterol, an Angiotensin Converting Enzyme (ACE) inhibitor for the High Blood Pressure, maybe a pill that obliterates your appetite so you “don’t eat so much”, and so on.

Boom…nice little drug cocktail for you.

Hundred$, if not thousand$ a month for Big Pharma.

If you had a spot on your lung, your doctor would immediately recommend you stop smoking. But in our obesity/blood sugar spectrum gone awry, your doc flies right past the “what’s causing the problem” stop on our tour, and lands smack dab in the pharmacy. Not one mention of stopping the offending activity.

What Is The Offending Activity?

It is the consumption of carbohydrates. More specifically, it is eating more carbohydrates than the body can put to good use.

Since carbs provide no structural support for any cells whatsoever, their only purpose in the body is for use as fuel. When they can’t be used as immediate fuel, for reasons we’ll get to in this series, the body has to do something with them. So it stores them for later.
