Your Gut, Your Bones, and Why Being Well-Fed Is a Radical Act

Episode Script

Thanks Toni. We've got a good one to wrap the week.

Three things on the table today — your gut, your bones, and your relationship with food. All very Friday. All genuinely worth knowing.

Start with the gut, because I keep seeing women in the menopause communities online describing this moment where their digestion just... changes. Not dramatically. Not "something is wrong" dramatically. More like: they've eaten the same breakfast for ten years and suddenly it's making them bloated. Or they've never had constipation in their life and now it's showing up regularly. And when they bring it up, they're told it's stress, or getting older, or maybe IBS.

Dr. Trisha Pasricha was on Dr. Mary Claire Haver's podcast — recorded at the Aspen Ideas Festival — and her title is worth saying out loud: neurogastroenterologist at Beth Israel Deaconess Medical Center, assistant professor of medicine at Harvard. She wrote a book called You've Been Pooping All Wrong, which is a title I respect enormously. And she makes the connection that a lot of doctors aren't making in those five-minute appointments: estrogen isn't just a reproductive hormone. It has a direct relationship with the bacteria that live in your gut.

Here's how she explains it. The gut microbiome — that's just the mix of bacteria living in your digestive system — is partly regulated by estrogen. When estrogen drops during perimenopause, that bacterial community shifts. Some of the strains that help with smooth digestion become less dominant. The gut lining can become more sensitive. Motility — meaning how quickly food moves through your system — can change in either direction. So the bloating isn't imaginary. The new constipation isn't just stress. It may genuinely be the hormonal shift showing up in your gut.

She also talks about the gut-brain connection, which is real and well-documented. Your gut and your brain communicate constantly, through a channel called the vagus nerve. And when the gut is unhappy — inflamed, dysbiotic, sluggish — it feeds back into mood and cognitive function. Which means some of the brain fog and mood disruption in perimenopause might have a gut component that nobody is looking at.

What does she recommend? Nothing revolutionary, but the basics are worth stating clearly. More fiber — most women are eating about half of what they need. Fermented foods like yogurt, kefir, kimchi, and sauerkraut, which early research suggests may help support healthy gut bacteria during hormonal transitions. And actually looking at the gut as part of the menopause picture — not a separate system operating independently.

My take: I think this is a genuinely underexplored connection, and the fact that it's coming from a Harvard gastroenterologist rather than a wellness influencer matters. The research is still early. We don't have large randomized trials specifically on menopause and the microbiome yet. But the biological mechanism is solid, and the practical suggestions are low-risk. If your digestion has changed in the last year or two and nobody's connected it to your hormones, it's worth bringing up — specifically, not just "I've been more bloated." Ask whether the hormonal shift could be involved.

Bones. This one I want you to sit with for a second.

There was a piece in The Guardian this week by Dr. Ranjana Srivastava, and it opens with a patient. Sixty years old. She fractured her pelvis. And the way it happened was — she slid on the floor. Not a fall down stairs. Not a car accident. She slid, the way you might slide in socks on hardwood, and her pelvis broke.

She didn't know her bones were fragile. There was no warning. No pain leading up to it, no stiffness that would have told her something was wrong. That's what makes bone thinning after menopause so quietly dangerous — it's completely silent until it isn't.

Estrogen does a lot of things, and one of them is maintaining bone density. When estrogen drops, bone breakdown starts to outpace bone rebuilding. Not in a dramatic way you'd notice. In a slow, invisible way. By the time a fracture happens, years of thinning may have already occurred.

The standard tool for measuring bone density is a DEXA scan. And Dr. Srivastava's point — which I think is the most important thing in this piece — is that the scan number alone isn't enough. Two women can have the same scan result and have very different actual fracture risk, depending on their history. Smoking. Alcohol. Whether they've had a previous fracture. How much they weigh. Whether they're on certain medications. A thorough conversation with a doctor who knows your full picture matters as much as the number.

And yet — most women don't get that conversation. They get a number, maybe a referral, maybe a pamphlet. The Guardian piece is framed as a call for better assessment, not just better scanning. I agree with that completely.

Here's the practical piece: strength training and weight-bearing exercise are the most evidence-backed lifestyle tools for protecting bone density. Not walking — actual resistance work, where your muscles are pulling on your bones. That mechanical stress is what signals the body to maintain bone mass. If you're not doing any form of resistance training right now, this is the reason to start. Not to lose weight. Not to look different. To keep your skeleton strong enough that a slip on the floor doesn't end in a fracture.

And if you're over 50 and you haven't had a DEXA scan, it's worth asking your doctor about it. Not to create anxiety — to get a baseline. You can't address something you can't see.

The third thing is less about a specific health finding and more about a framing that I think is worth taking into the weekend.

Lisa Kilgour, a registered nutritionist, was on the podcast Not Your Mother's Menopause this week, and her core argument is this: choosing to eat enough — to actually nourish yourself, not perform restriction — is, at this moment in culture, a radical act.

She's talking about the return of the very thin aesthetic in fashion and media. And she makes a point that's worth chewing on. She says that every time women gain cultural power, there tends to be a counter-movement that encourages them to shrink physically. Less space, less presence, less visible mass. And she frames the choice to eat well, sleep enough, and actually feed your body as a kind of resistance.

I find the political framing interesting, but what I actually want to talk about is the practical piece underneath it, because it connects directly to menopause.

Women over 45 typically need more protein than they were eating in their thirties, not less. Muscle mass is harder to build and easier to lose. Bone density requires adequate nutrition, including calcium and vitamin D, but also just... enough calories overall. Restrictive eating at this stage of life can accelerate the muscle loss and bone thinning that menopause is already driving.

And yet the cultural pressure runs exactly the other way. Women in menopause — who are often dealing with some weight redistribution that feels unfamiliar — are bombarded with messaging about eating less, cutting carbs, shrinking back down. Some of that content has legitimate evidence behind it. A lot of it doesn't. And some of it is actively working against what the body needs to stay strong.

Kilgour's point is that well-fed is not the same as overindulgent. Well-rested is not lazy. And choosing to prioritize those things, especially when the culture is telling you to do the opposite, takes some actual conviction.

I'm not going to tell you what to eat — that's not what this show does, and it's not what she's doing either. But the idea that nourishment is something to defend rather than feel guilty about feels like the right note to end a week on.
