Hair “longevity” sounds like peak wellness nonsense. Until you realize it might be one of the most clinically believable plays we’ve seen in a while. 🧬

If I told you there were early trials using compounds to wake up dormant follicles, you’d assume it’s marketing. But some of this work is real biotech—stem cells, signaling pathways, and interventions designed to actually restart the growth phase.

𝗧𝗵𝗲 𝗖𝗹𝗶𝗻𝗶𝗰𝗮𝗹 𝗥𝗲𝗮𝗹𝗶𝘁𝘆:

1️⃣ 𝗕𝗶𝗼𝗹𝗼𝗴𝘆, 𝗻𝗼𝘁 𝘃𝗮𝗻𝗶𝘁𝘆: Pattern baldness is just follicles shifting into a dormant cycle.

2️⃣ 𝗩𝗶𝘀𝗶𝗯𝗹𝗲 𝗘𝗻𝗱𝗽𝗼𝗶𝗻𝘁𝘀: You can’t see your telomeres, but you can see density. That makes this space measurable and fundable.

3️⃣ 𝗧𝗵𝗲 𝗪𝗮𝗿𝗻𝗶𝗻𝗴: The hype will be loud. Expect peptides and "miracle serums" everywhere.

Swipe through the images to see what is real science and what is just marketing fluff. 👉

If I told you there was a pill that reduced your risk of cognitive decline by 19%, you’d ask me for a prescription immediately.

The truth? You don’t need a pill. You need to manage your Blood Pressure. 🩺

In the longevity space, we tend to obsess over the "sexy" stuff—peptides, CGMs, cold plunges. We ignore BP because it’s boring and doesn't sell subscriptions.

But as a physician, I have to look at the data:
1️⃣ 𝗕𝗿𝗮𝗶𝗻 𝗛𝗲𝗮𝗹𝘁𝗵: High BP ages your brain. Keeping systolic under 120 cuts the risk of Mild Cognitive Impairment.
2️⃣ 𝗧𝗵𝗲 𝗘𝗹𝗲𝗰𝘁𝗿𝗼𝗹𝘆𝘁𝗲 𝗧𝗿𝗮𝗽: I see health-conscious patients drinking massive sodium loads in electrolyte mixes without the activity levels to match.
3️⃣ 𝗡𝗲𝘄 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱𝘀: The 2025 guidelines are stricter. <120/80 is the goal.

Check the images above for non-obvious ways to lower it (including one that requires zero cardio).

Wellness is about how you feel. Longevity is about what the data says. 📉

It’s easy to confuse the two. We see "longevity" slapped on expensive supplements and luxury retreats, making it look like the wellness boom of a decade ago—just with a higher price tag.

But as a physician, I need to make the distinction clear. Wellness focuses on the immediate feeling of being "better" (which has value!). True Longevity Medicine, however, is objective.

It must be:
1️⃣ Measurable: We track biomarkers, not just vibes.
2️⃣ Evidence-based: Protocols built on clinical research, not marketing.
3️⃣ Outcome-driven: Tangible changes in healthspan, not temporary relief.

Check out the images above to see exactly where the line is drawn between the two.

In the comments: Do you track your health data 📈 or focus more on how you feel 🧘‍♀️? I want to see where this community stands.

Most people assume “healthy flour” just means buying gluten-free or whole wheat.

But the real answer isn't about the label. It’s about the anatomy of the grain—and what commercial processing strips away.

Whole wheat flour includes the bran, germ, and endosperm. This is crucial because that trifecta retains:
🌾 Fiber
🌾 B vitamins
🌾 Vitamin E
🌾 Minerals (iron, zinc, magnesium)
🌾 Anti-inflammatory phytochemicals

Compare that to refined flour. Manufacturers strip away the bran and germ (where the vast majority of nutrients live) to create a smoother texture and longer shelf life.

The result? You get a whiter bread, but you lose the fiber and the metabolic benefits. Even if it says "enriched," they are just spraying a few vitamins back onto a nutritionally empty starch. It does not replace the full profile of the whole grain.

Here is my protocol for choosing flour:

If you tolerate gluten: Opt for actual whole wheat or whole-grain flours. Look for "100% whole grain" on the package.

If you are baking gluten-free: Stop buying ultra-processed potato/corn starches. Look for flours with natural fiber and protein, like oat, buckwheat, almond, or quinoa.

Save this post for your next grocery run. Your gut microbiome (and your glucose levels) will thank you. 🍞🌾

Most people think fasting = starving yourself. The science says otherwise. 👇

Fasting is one of the oldest longevity practices in history, but we finally understand the mechanism. When I advise patients to fast beyond 12 hours, we are looking for metabolic switching. This is the state where your body stops burning sugar and starts burning stored fat for fuel.

That switch does something powerful:
✨ Increases autophagy (your body’s cellular cleanup mode)
✨ Improves insulin sensitivity
✨ Reduces systemic inflammation
✨ Enhances cognitive function
✨ May slow the aging process

Let’s be clear: Fasting is not starvation. It is a voluntary, controlled strategy backed by decades of research—and guided by your biology.

Whether it's 16/8, 5:2, or a 24-hour reset, fasting allows you to reset metabolic pathways. The key is knowing which method works for your specific physiology... and who shouldn’t fast at all.

Here is the breakdown of what matters:
🔥 The physiology of metabolic switching
🧠 Why fasting improves brain performance
🧬 How autophagy rejuvenates your cells
⛔ Who needs to avoid fasting
🧩 How to start safely (using my specific ramp-up protocol)

Fasting isn’t a trend. It’s a tool for long-term health. Save this post and start simple: try a 12/12 window tonight.

Ever wondered why crunches aren't flattening your tummy?

As we enter the holiday season full of temptations, this is a reminder of how to get ahead of your new year's resolutions.

Here's what I tell my patients: your waistline reveals more about your heart health than your weight on the scale. Men over 40 inches, women over 35 — that's when risk spikes, regardless of BMI.

The real issue? Visceral fat. It wraps around your organs and drives inflammation. But sometimes that belly bulge is just bloating from FODMAPs (onions, garlic, sugar alcohols). That's fixable in days.

The game-changer most people miss: your Transversus Abdominis (TVA). It's your body's natural corset. Stomach vacuums — not crunches — train it. Five minutes daily. Many of my patients see 1-2 inches off their waist in weeks.

This isn't about vanity. It's about vitality.

Aging isn’t classified as a disease.
At least not according to the FDA.

That single decision shapes everything about longevity research.

You can’t run trials on “preventing aging.”
You can’t design studies around “anti-aging interventions.”
You can’t even use aging itself as an endpoint.

So researchers play regulatory whack-a-mole instead.
Alzheimer’s here. Cardiovascular disease there. Diabetes somewhere else.
Each disease gets its own silo, its own funding, its own 20-year process.

Meanwhile the root cause—aging itself—stays untouchable.

And yet… that’s exactly how the next longevity drug may have already slipped through.

A team at UAMS was studying toxic protein clumps in Alzheimer’s brains. Not aging. Not longevity. Just pathology.

They screened more than 1,800 FDA-approved drugs using computational tools.
The unexpected winner? Ezetimibe.
A $2 generic cholesterol pill from 2002.

Then they looked at real-world data: 950,000 patient records.
People taking ezetimibe had an 87% lower risk of dementia.

For perspective: our newest Alzheimer’s drugs slow decline by maybe 30% and cost $26,000 per year.
This forgotten generic outperformed all of them.

Yes—this is early. Retrospective data can mislead.
We need prospective trials.

But here’s the reality. When true longevity research gets scraps, drug repurposing becomes one of the most powerful tools we have.

Because millions of people are already taking drugs that might be quietly extending their healthspan:

• Metformin may influence lifespan
• Rapamycin may slow aging pathways
• GLP-1s may reduce dementia risk and more
• And now ezetimibe may protect the brain

The best longevity candidates aren’t coming from purpose-built aging labs.
They’re hiding in plain sight inside medications designed for other conditions.

This is longevity today.
Not waiting 30 years for new drugs.
But finding accidental breakthroughs in the data we already have.

What drug do you think will be the next unexpected longevity win?

Hormonal IUDs are back in headlines. Here is what the new JAMA study actually showed.
• ~79,000 users of levonorgestrel IUDs were followed.
• Breast cancer risk was 40% higher in relative terms.
• The absolute risk stayed low. About 14 extra cases per 10,000 women over several years.

What we know
• The signal points to synthetic progestins.
• Natural. bioidentical progesterone is not showing the same increase in current data.
• This is physiology. not panic.

How to decide
1. If your hormonal IUD works well, your absolute risk remains low.
2. If you have strong family history or prefer to avoid hormone-related risk, consider the copper IUD.
3. Talk with your clinician about your personal risks. benefits, and values.

My take
Women deserve clear data and better options. We should not settle for “good enough.”

Educational only. Not medical advice.
