Blood Sugar 101 for Women Over 40
Until pretty recently, I thought blood sugar was something only people with diabetes needed to worry about.
I didn't connect it to my energy crashes. I didn't connect it to my afternoon cravings, my anxiety, my brain fog, or the stubborn weight that had started creeping around my midsection. I just thought those things were part of getting older.
It wasn't until I went through my health coaching certification and spent two weeks wearing a Continuous Glucose Monitor that everything changed.
A CGM is a small device you wear on your arm that tracks your blood sugar in real time. Those two weeks were genuinely eye opening. I could see exactly how every meal, every stressor, and every choice I made throughout the day was affecting my body, and some of what I saw completely surprised me.
One afternoon I was sitting down to take a certification exam. I hadn't eaten much that day, just some chips and salsa. I was stressed, focused, and in the middle of the test when I looked at my monitor and saw my blood sugar had spiked higher than it ever had. Not from a huge meal. From chips, salsa, and stress.
That moment showed me something I hadn't fully understood before. Stress raises blood sugar too. Not just food.
Another time I went to Qdoba and ordered what I thought was a pretty balanced bowl. Chicken, rice, beans, veggies. Felt like a solid healthy lunch. My monitor told a completely different story. My blood sugar spiked significantly after that meal, and I realized that rice and beans, even in a "healthy" bowl, were affecting me in ways I never expected.
Those two weeks changed how I eat, how I think about food, and how I think about my health in general.
So What Is Actually Happening Inside Your Body?
When you eat something sugary or starchy, your blood sugar rises. Your pancreas responds by releasing a hormone called insulin, whose job is to take that glucose out of your bloodstream and move it into your cells to be used for energy. In small amounts and occasional spikes, this is completely normal and healthy.
The problem happens when blood sugar spikes too high, too often.
When that happens, your pancreas keeps pumping out more and more insulin trying to keep up. Over time your cells start becoming overwhelmed and less responsive, a condition called insulin resistance. And when there is more glucose than your cells can use, your body stores the excess as fat, often right around the midsection.
This is why belly fat and blood sugar are so deeply connected. It isn't just about willpower or eating too much. It is often about what repeated blood sugar spikes are doing inside the body over time.
Why This Gets Harder in Perimenopause
Here is something most women don't realize. Estrogen actually helps your cells respond to insulin properly. As estrogen begins to decline during perimenopause, your cells can become less sensitive to insulin, which means your body has to work even harder to manage blood sugar than it used to.
This is one of the reasons women in perimenopause often notice changes in their energy, their cravings, their mood, and their weight even when their habits haven't changed much. Your body is working with a different hormonal environment than it was ten years ago.
Unstable blood sugar can contribute to:
Energy crashes throughout the day
Constant hunger and cravings that feel impossible to control
Anxiety and feeling on edge
Brain fog and difficulty focusing
Poor sleep and waking up in the middle of the night
Stubborn weight gain especially around the belly
Mood swings and irritability
And over time, a higher risk of prediabetes, type 2 diabetes, and cognitive decline
That last one is something I take very personally. My dad passed away just a few months ago from Alzheimer's, and watching that disease take someone I loved so deeply has made me look at brain health in a completely different way. The research connecting chronically high blood sugar and insulin resistance to long term cognitive decline, including Alzheimer's and dementia, is something every woman deserves to know about. Some researchers have even started referring to Alzheimer's as Type 3 diabetes because of how closely the two are linked.
I can't change what happened to my dad. But I can make choices every single day that support my own brain health, and I can share what I've learned with you. It is one more reason why what we eat matters more than most of us realize.
What a Blood Sugar Balanced Day Actually Looks Like
The good news is that eating for stable blood sugar does not have to feel like another complicated diet or a long list of rules.
The simplest framework I come back to again and again is this: protein, fat, and fiber at every meal.
When you build your meals around those three things, you give your body what it needs to release glucose slowly and steadily rather than in a big spike. You stay fuller longer, your energy stays more even throughout the day, your cravings quiet down, and your mood and focus improve.
Not perfect. Not rigid. Just protein, fat, and fiber as your starting point at every meal.
Some easy ways that looks in real life:
Eggs with avocado and vegetables at breakfast instead of toast or cereal alone
Adding chicken or salmon to a salad with olive oil dressing instead of a grain bowl with very little protein
Snacking on nuts and cheese instead of crackers or fruit on its own
Pairing any carbohydrate with a protein source to slow down how quickly it affects your blood sugar
