The Truth About Hormones &Body Fat
If you’re a woman in midlife witnessing changes in your body, let’s be honest—hearing one more expert say “just move more and eat less” might make you scream. That tired, oversimplified advice ignores the very real ways our bodies change—and the decades of life we’ve already lived in them.
Midlife, generally defined as the ages between 37 and 65, isn’t just a calendar phase. It’s a biological, emotional, and identity-shifting chapter. For women, it often marks the beginning of perimenopause—the transitional period leading up to menopause, when the ovaries gradually produce less estrogen. Menopause itself is defined as the 12-month mark after your final menstrual period, but the hormonal fluctuations and symptoms often begin years before and can last well beyond that point.
To really understand what’s happening in our bodies now, we have to rewind the clock.
From puberty, our bodies have been shaped by an elegant hormonal dance. Estrogen, progesterone, and to a lesser extent testosterone, govern everything from our cycle to our skin, from our energy to our emotional responses. These hormones rise and fall in predictable patterns until they don’t. And when they don’t, you feel it.
Hot flashes. Sleep disruptions. Brain fog. Mood swings. Slower recovery from workouts. A scale that doesn’t seem to budge no matter what you do. And the silent undercurrents like the gradual loss of bone density—osteopenia—that often go unnoticed until it’s too late.
These aren’t random annoyances. They’re signals. And they deserve to be understood.
In this post and in today’s podcast episode, I talk with registered dietitian and research wizard Maryann Jacobsen about what actually helps us thrive during perimenopause and menopause. We get into why muscle is metabolic gold, why cardio isn’t always the answer, and how biofeedback your body’s own cues like hunger, energy, sleep, and mood can tell you more about what’s working than any calorie tracker or influencer’s reel ever could.
We also challenge the idea that your bathroom scale is the best measure of health. Spoiler alert: it’s not. Tools like DEXA scans provide deeper insight into your bone density and lean mass—two things that matter more than “weight” ever could in this stage of life. And while your smart scale using bioelectrical impedance might not be as accurate, it can still help you track general trends if you know how to interpret it.
One part of our conversation that hit me hard was Maryann’s mention of the body fat research around fertility. Scientists have found that a minimum of 17% body fat is required just to get a menstrual cycle, and about 22% is needed to maintain ovulation. But here’s the real shocker: in mature women, regular ovulatory cycles are often supported best at 26–28% body fat. (PMID: 3117838, 2282736) That means what many of us have been taught to chase ultra-lean physiques (around 17 BF% or so), chronic calorie restriction, or overtraining can actually backfire on our reproductive health, bone health, and overall vitality.
In populations where food is scarce or physical demands are high, we see patterns: delayed first periods, longer gaps between births, earlier menopause. It’s the body adapting for survival. But in modern life, we sometimes impose these same conditions on ourselves in the name of “fitness.”
And while estrogen usually gets the spotlight in menopause care often treated as the main character it’s progesterone that deserves a standing ovation. Many women are told they “need progesterone” just to protect themselves from estrogen’s effects, as if it’s merely a buffer. But that undersells its brilliance.
The name progesterone literally means “pro-gestation,” but its impact goes far beyond fertility. Progesterone is a master regulator. It stabilizes tissues, supports metabolic balance, calms inflammation, protects against stress, and even plays a role in brain health. While estrogen stimulates, progesterone shields. While estrogen builds, progesterone restores.
Fascinatingly, our bodies produce far more progesterone than estrogen especially after ovulation and during pregnancy. That’s not a fluke. It reflects just how critical progesterone is to our overall well-being.
So when ovulation slows or disappears in midlife, it’s not just your period going quiet. It’s this entire downstream network of hormonal resilience especially progesterone that starts to fade. And that’s when symptoms ramp up.
Understanding this isn’t just about managing menopause. It’s about honoring your biology, updating your strategy, and supporting your body like the powerful, responsive system it actually is.
If we want to balance and optimize our hormones in midlife, we have to re-evaluate our goals. This isn’t about grinding harder it’s about getting smarter. And to get smarter, we need to zoom out.
Ovulation isn’t just some fertility footnote-it’s the main event of your cycle. But many of us were taught that the bleed is the cycle. Nope. That’s just the after-party. The headliner? Ovulation.
Why does this matter in midlife?
Because ovulation is what triggers the production of progesterone a hormone that plays a critical role in metabolism, mood, sleep, brain function, and bone health. And spoiler: progesterone is the first to dip off the radar as we enter perimenopause. That’s why your energy feels off, your sleep gets weird, and your tolerance for stress tanks. Your body isn’t broken—it’s adapting.
Here’s where things click into place: your body will only ovulate consistently if it feels safe and nourished. That means you’re eating enough, not overtraining, and not living in a cortisol-fueled chaos spiral.
Ovulation isn’t just about reproduction it’s a vital sign of health.
And the two hormones that anchor your entire cycle, estrogen and progesterone, do so much more than regulate periods.
From bone density to brain function, from insulin sensitivity to mitochondrial health, these hormones influence nearly every system in your body. So, when they fluctuate…. or flatline… you feel it. Not just in your body, but in your entire day to day experience.
So, let’s break the rules, rewrite the midlife playbook, and finally start listening to the wisdom our bodies have been whispering all along.
