Someone sits down, a little sheepish, and tells me they've started a GLP-1
medication. Ozempic, Wegovy, Mounjaro, one of that family. Then they ask some
form of the same question: "So do I still have to do all the other
stuff?"
The other stuff being, you know. Vegetables. Walking. Sleep. All the things
I've been gently nagging people about for thirty-five years.
I get why they ask. These medications are genuinely impressive, and the
internet has done a spectacular job of selling them as a get-out-of-jail-free
card. Take the shot, skip the salad, live forever. It's a lovely fantasy.
A big new study just poured a bucket of cold, useful water on it. And honestly,
the answer it gives is more encouraging than the fantasy ever was.
## What they actually looked at
Researchers followed nearly 100,000 people with type 2 diabetes for several
years. This was a large, carefully conducted study from the Veterans Affairs system, so we're talking about real people living real lives, not in lab
conditions.
They tracked two things.
First, whether people used a GLP-1 medication. Second, how many of the eight
healthy habits they kept up. The habits were refreshingly unsexy: a
good-quality diet, physical activity, not smoking, getting restful sleep,
not drinking heavily, managing stress, staying socially connected, and steering
clear of opioid misuse.
Then they watched for what doctors call MACE, which stands for major adverse
cardiovascular events. In plain English, that's the big scary stuff. Heart
attack, stroke, and death from heart disease.
## What they found
Here's where it gets good.
The people who kept up all eight healthy habits, compared to the folks doing
one or fewer, had a **60 percent lower risk** of those major heart events.
Sixty. That's not a rounding error. That's the kind of number a drug company
would sell its soul for.
The GLP-1 medication on its own lowered the risk by about **16 percent**. Real,
meaningful, worth having.
And when people did both, took the medication and lived a healthy life, the
risk just kept dropping. The combination beat either approach on its own.
Read that one more time, because it's the whole point. The medication and the
habits are not competing for the same job. They're teammates. And the team
wins.
## Why I love this
Because it settles an argument I'm tired of having.
There's a camp that treats these medications like cheating, as if losing weight
or protecting your heart with pharmaceutical help doesn't count. That's
nonsense, and it keeps people who could benefit from ever asking for help.
There's another camp that treats the medication like a hall pass. Take the
shot, ignore everything else, the science has got you covered. Also nonsense,
and this study is the result.
The truth sits comfortably in the middle, where the truth usually hangs out.
The medication is a powerful assist. Your daily habits are still the main
event. Put them together, and you get more than the sum of the parts.
The drug was never going to do all the heavy lifting while you watched from the
couch,
eating Doritos. It's a teammate, not a substitute. And like any good
teammate, it plays a lot better when you show up too.
## The honest caveat
I'd be a lousy doctor if I handed you the exciting number and skipped the fine
print.
This study was done mostly in male veterans with diabetes. That's a specific
group. So the precise figures, the 60 percent and the 16 percent, are their
numbers, not a promise stamped onto every person who reads this. My patients
are overwhelmingly women navigating midlife, and I'd love to see this exact
study run in that population.
But here's the thing about the principle underneath the numbers. It doesn't
wobble. "Medication plus healthy habits beats either one alone" is
about as sturdy a finding as we have in medicine, and it shows up again and
again across different groups, different drugs, and different diseases. This
study just added a very large, very clear brick to that wall.
## So what do you actually do
If you're on a GLP-1, or thinking about starting one, here's your marching
orders, and they're wonderfully simple.
Keep taking the medication if it's right for you. And keep doing the boring,
beautiful things that were protecting your heart long before any of these drugs
existed. Walk. Sleep. Eat like you love yourself. Call your friends. Manage the
stress that's been chewing on you.
You don't have to choose between the pharmacy and the produce aisle. That was
always a false choice. Do both.
Your heart is keeping score. And this study says it's counting every good
decision you make, whether it comes in a syringe or a pair of walking shoes.
Pick one small habit this week. Just one. Stack it on whatever you're already
doing. That's how this works. Not a heroic overhaul, just one more good thing
on top of the last good thing.
The magic was never in the wand. It was in you all along. The medication just
helps you get there faster.

You walk into the kitchen with a purpose. A clear, specific purpose. You stand there. The purpose is gone. You open the fridge, hoping it left a note.
If you're somewhere in your late 40s or 50s, you know this moment well. The lost word. The name that vanishes mid-introduction. The reading glasses you're wearing while you tear the house apart looking for your reading glasses. Women call it brain fog, and for years, the medical response was somewhere between a shrug and a pat on the head.
A new study out of the UK just gave us something much better than a shrug.
What they did
Researchers examined 14,234 women aged 45 to 55. They sorted them into three groups: premenopausal, perimenopausal, and postmenopausal. Then they asked everyone about their symptoms over the previous two weeks and ran the whole group through eight cognitive tests measuring memory, attention, reasoning, and mental speed.
The goal was simple. Do the women who feel foggy actually perform worse on tests that measure thinking? For years, the research on this has been a mess of contradictions, so a sample this large is a real gift.
What they found
The first result surprised no one. Perimenopausal and postmenopausal women were much more likely to report brain fog and memory problems than younger women, with roughly 30% higher odds. The fog is common, it's real, and it clusters right around the hormonal transition. If you've felt it, you have plenty of company.
The second result is the one worth taping to your bathroom mirror.
On the actual cognitive tests, the scores barely moved. Across all three groups, performance was essentially the same. Perimenopausal women, who reported the most fog, actually scored a touch higher on accuracy than everyone else.
Read that again. The women who felt the foggiest tested slightly sharper.
The association between feeling foggy and performing poorly on tests was weak. The connection between feeling foggy and feeling anxious, low, or moody was much stronger.
What it actually means
Here's the part I want you to sit with, because it's easy to misread.
This does not mean the fog is imaginary. The researchers went out of their way to say so, and I'll say it louder: the symptoms are real, they're distressing, and they can wreck your quality of life. Nobody is telling you it's in your head.
The study suggests that the fog is not coming from a brain that's breaking down. It's coming from everything piled on top of the brain. Sleep shredded by 3am hot flashes. Mood swinging on a hormonal tide. Anxiety humming in the background. Fatigue that no amount of coffee fixes. Stack all of that on any human, at any age, and they'll feel foggy too.
Your brain isn't the problem. Your brain is doing calculus while someone sets off a fire alarm and steals your sleep. Of course it feels sluggish. It's overloaded, not offline.
There's also a timing quirk the researchers flagged. A cognitive test is a 15-minute snapshot in a quiet room. Real life is misplacing your keys during a chaotic Tuesday while three people ask you questions. The little day-to-day lapses that drive you crazy may simply not show up on a tidy test. That gap between how you feel and how you score is not a failure of your brain. It's a limit of the test.
Why this is good news
Because "your brain is declining" is a dead end. There's nothing to do with it except worry, and worry makes the fog worse.
"Your sleep, mood, and hormones are driving this" is a to-do list. Every one of those things responds to attention.
Sleep is the big lever. Get the night sweats under control, and a stunning amount of fog lifts on its own. Movement helps, and not in a vague way, it directly improves mood, sleep, and mental clarity. Managing anxiety and low mood, whether through therapy, medication, or both, tends to clear the mental windshield. And for a lot of women, addressing the hormonal changes directly, hot flashes and all, quiets the whole system down.
None of this requires you to accept that you're losing your edge. You aren't. You're running a marathon through a hormonal thunderstorm, and the fog is the weather, not the runner.
One honest caveat
This study looked at the transition itself, not the long game. It doesn't settle the separate and important questions about hormones and long-term brain health decades down the road. Those matter, and they deserve their own conversation. But the fear that keeps women up at night, the one that whispers this is the beginning of the end for my mind, is not what this data shows. Not even close.
So the next time you're standing in the kitchen wondering why you came in, give yourself the same grace you'd give a friend running on four hours of sleep. You're not slipping.
You're adjusting. And you're going to be just fine.
Based on Naysmith et al., "Cognition and the menopause transition: cross-sectional evidence from a large community cohort," npj Women's Health, 2026.
I have spent 35 years telling women to eat better and move more. I stand by every word. But a new study just walked into the room, cleared its throat, and announced that I may have been burying the lede.
Researchers at Oregon Health & Science University published a study in the journal SLEEP Advances examining what actually predicts how long Americans live. They compared county-level life expectancy data with CDC survey data collected from 2019 through 2025. Then they lined up the usual suspects: diet, exercise, social isolation, smoking, and sleep.
Here's the ranking that made me put down my coffee.
Smoking came in first. No surprise there. Smoking has been the heavyweight champion of shortening lives since before I was in medical school.
Second place? Sleep. Not diet. Not exercise. Sleep.
People who regularly slept less than seven hours a night showed a stronger link to shorter life expectancy than those with poor diets, those who never exercised, or those who were socially isolated. The lead researcher is a sleep physiologist, a man whose entire career is built on the belief that sleep matters, and even he said the strength of the connection surprised him.
Let that sink in. The guy who gets paid to be impressed by sleep was impressed by sleep.
If you're a woman over 40, I don't need to tell you that sleep gets complicated. You already know. You're the one staring at the ceiling at 3 AM, doing laundry math, and wondering why your body decided the middle of the night was the perfect time for a personal heat wave.
Estrogen and progesterone help regulate sleep. When those hormones start their midlife exit, sleep is often the first casualty. Night sweats wake you up. Anxiety keeps you up. And the sleep you do get is often lighter and more fragmented than it used to be.
So here's the frustrating part of this study, and also the hopeful part. The frustrating part: the thing that predicts your longevity better than your diet is also the thing menopause loves to sabotage. The hopeful part: sleep is fixable. Unlike your genetics, your age, or your mother-in-law, sleep responds to intervention.
The target is seven to nine hours a night. Not on weekends. Not averaged over the month like some kind of sleep 401(k). Nightly.
And quality counts. Eight fragmented hours of tossing and waking may not deliver what seven solid hours will. If you're hitting the pillow count but still waking up feeling like you've been hit by a small truck, that's worth a conversation with your doctor.
A few things that actually move the needle:
Keep a regular schedule. Your brain loves a routine more than a golden retriever loves a tennis ball. Same bedtime, same wake time, even on Saturdays.
Put the phone down an hour before bed. Doomscrolling at 11 PM is not self-care. It's a caffeine drip for your nervous system.
Cool the room. Especially if hot flashes are part of your nightly programming. A cooler bedroom helps everyone, but it helps you more.
And if hormones are wrecking your nights, treat the hormones. This is where I get on my soapbox. Too many women white-knuckle through years of terrible sleep because someone told them it's just part of getting older. Bad sleep is a symptom, not a sentence. Hormone therapy, when it's appropriate for you, can transform sleep. So can treating sleep apnea, which is wildly underdiagnosed in midlife women because it doesn't always look like the snoring husband version.
We have spent decades treating sleep like the negotiable part of health. Diet and exercise got the magazine covers. Sleep got whatever hours were left over after everything else.
This study suggests we've had it backward. You cannot out-supplement, out-run, or out-kale a chronic sleep deficit. The most powerful longevity tool you own might be the one sitting in your bedroom, already paid for, waiting for you to take it seriously.
Tonight, when you're deciding between one more episode and turning in, remember: one of those choices is linked to a longer life. And it's not the one with the cliffhanger.
Sleep well. Doctor's orders.
Menopause Is More Than Hot Flashes. And Medicine Is Finally Catching Up.
For a long time, we boiled menopause down to a short list of symptoms. Hot flashes. Night sweats. Mood swings. A sudden, fierce loyalty to the nearest portable fan.
That list isn't wrong. It's just small.
The newer research suggests menopause is something much bigger than a handful of symptoms. It looks more like a whole-body transition, one that touches your heart, your bones, your metabolism, your muscles, your sleep, your inflammation, and even how your brain feels day to day. Not just a hormonal moment. A systems-wide event.
One recent analysis looked at hundreds of millions of lab measurements and found something worth paying attention to. A lot of these changes don't drift in slowly over the years. They show up more like a step than a slope, clustering around the menopausal transition itself.
That changes how we ought to think about the whole thing.
Because when menopause is only about symptoms, we miss the part that actually helps the most: getting ready before the symptoms show up.
From Reacting to Preparing
For most of medical history, the menopause conversation has been reactive. A woman develops symptoms. The symptoms get worse. Then, eventually, somebody talks about doing something.
But if your cardiovascular, metabolic, and bone changes are already underway years before your final period, waiting for symptoms is a little like waiting for a broken hip before you'll consider lifting weights. Technically, a plan. Not a great one.
The better conversation is about healthspan, not just symptom control. How well you live, not just how you feel this week. That distinction matters more than almost anything else here.
So What Actually Changes?
More than reproductive hormones, that's for sure. The effects reach into:
- Cholesterol and heart risk
- Bone strength and fracture risk
- Muscle mass and raw strength
- Insulin sensitivity and body composition
- Sleep and recovery
- Mood, focus, and energy
None of this means decline is your destiny. It isn't. But the physiology is real, and it deserves the same respect we give every other big transition in a person's health.
The Good News: You Can Get Ahead of It
Here's my favorite part. The most powerful tools for this transition are already sitting right in front of us. They're not glamorous. They're not expensive. They don't come with a slick startup pitch and a six-month waitlist.
They're the basics. The deeply proven, slightly boring, enormously effective basics.
Strength training. Muscle loss accelerates in midlife, especially without resistance exercise. Lifting weights protects muscle, builds bone, helps manage blood sugar, and keeps you steady on your feet. It also lets you carry every grocery bag in from the car in one heroic trip, which I consider a legitimate medical goal.
Protein. As we age, protein matters more, not less. It's worth putting on the plate on purpose, rather than hoping it sneaks into lunch by accident.
Cardio. Aerobic exercise is one of the strongest interventions we have for the heart, the brain, metabolism, and mood. The evidence here is almost boring in its consistency.
Sleep. Menopause loves to wreck sleep, and bad sleep quietly damages everything else: recovery, appetite, blood pressure, thinking, and patience. Protecting your sleep may be the highest-return decision you make in midlife.
An honest hormone therapy conversation. Hormone therapy is no longer the scary, one-size-fits-all topic many of us were taught to fear. The modern version is individual, risk-based, and grounded in much better evidence. Not everyone needs it. Not everyone is a candidate. But everyone deserves a real conversation about it.
The Bigger Point
We spend a lot of energy chasing futuristic anti-aging breakthroughs while overlooking a massive biological transition happening right in front of us. Menopause isn't a niche topic. It affects half the population directly, and pretty much everyone else through the women they love.
And here's the most encouraging thing the research keeps telling us: healthy aging doesn't start at 70. It starts long before getting older feels like an actual thing.
Someday, medicine will hand us better biomarkers, sharper therapies, maybe even ways to nudge the biology of aging itself. I'm genuinely excited for that. But today, the fundamentals still do the heavy lifting.
Move. Lift. Sleep. Eat well. Stay ahead of it. Pay attention early.
Sometimes the most powerful longevity tools are the least exciting ones. And honestly, for all of us, that's pretty good news.
