I'm turning 44 this month, but my Biological Age is 29.
I'm literally aging in reverse, with receipts. My humble history and what got me here.
I turn 44 in just a couple of weeks. My biological age came back at 29.2.
That’s 14.7 years younger than the number on my license, and it isn’t a typo, a filter, or a good-lighting situation. It’s a real lab result. My body is running almost fifteen years behind my birthday, and it’s moving the right direction.
Here’s the part people don’t expect: I did not get here by being lucky.
At my actual calendar age 29—I was sadly over 300 pounds. Even after losing 150 of them, I had IBS so debilitating I walked away from a corporate career because I couldn’t be that far from a bathroom. Add years of hormonal chaos, lipedema diagnosis, a full hysterectomy, and a stack of surgeries most people don’t know about, and you get a body that spent a long time working against me.
So when a 29-year-old biological age shows up next to that history, I need you to hear what it actually means. This is aging in reverse. On purpose. With the exact same strategies I use for every single client.
What biological age actually is
Your biological age isn’t how many birthdays you’ve counted. It’s how your body is functioning underneath: oxidative stress, inflammation, metabolic markers, the quiet chemistry that decides how fast you’re really aging. Function Health pulls it straight from your bloodwork. And it isn’t a one good day on camera. A number like 29.2 reflects what’s been happening in my body consistently, over time.
So let me say the thing my comments section always jumps to: I wasn’t born with good genes. I learned how to work with the ones I have.
The two things that got me here
They work as a pair.
The first is my DNA.
Methylation and detox pathways get tossed around as wellness buzzwords, equal parts hype and fear. Strip the noise away and they’re some of the biggest levers there are on how fast your cells actually age.
So I don’t guess at mine. I know which foods inflame me and which ones my body handles just fine. I know the nutrients I can’t convert well in their standard forms, so I take the forms my body can actually use instead of the ones on the shelf. I know which detox and hormone pathways need a little backup and which ones already run smoothly on their own, so I put my energy where it counts. Every food, every supplement, every decision runs through my own genetic blueprint first. That’s the whole premise of Body by Design®: roughly 500 genetic markers from one cheek swab, turned into a plan built for your body instead of outdated averages.
The second is using peptide therapy.
Here’s the quick version of why they work so well. Peptides are basically designed to mimic the innate compounds your body already makes on its own, the same signaling chemicals it produces less and less of over time. (Cough, cough, aging.) By replacing those key messengers, I’m literally handing my cells the commands they need to perform better.
Once I understood what my DNA was asking for, peptides became a big part of the precision tool for delivering it. Gut repair, recovery, metabolic support, the things my history left me needing more of.
For the past 5 years, I’ve been sending my cells the signals for healing all of the above, and with the performance chemistry of a 20-something 💅
Starting by reversing signs of autoimmune dysfunction due to leaky gut (think food allergies galore and snowballing sensitivity to all things enviro-chemical), then turning up hormone receptors to function more normally than they ever would alone, to finally mega mitochondrial cleanup following surgeries and an overall lifetime of poor decisions in decades past. All the things that can cause literal DNA damage, reversed.
These two are a powerhouse together, but each stands on its own. My DNA hands me the map of what my body’s actually working with. Peptides give my cells a direct signal to perform. I lean on both because both move the needle.
What this actually looks like day to day
It’s a lot less dramatic and micro-managed than you’d think.
It looks like strategic supplementation. Not 78 new bottles crowding the counter, just the specific nutrients my genetics say I need, in the forms my body can actually absorb. This is like the “easy button” for so many clients, and a big step toward optimization with foundational daily chemistry balancing, so you feel it ‘round the clock.
It looks like protecting my gut. After years of it being the thing that ran my life, I keep it intact by staying away from the specific foods my DNA says I get more inflamed from. Not a trendy elimination diet. My list, from my chemistry. Supplementing strategically when I can’t control the minutia or just need a night out.
It looks like keeping my hormones, my sleep, and my stress chemistry steady with basic daily habits, because I know exactly where those systems need attention and where they don’t. I’m not trying to optimize all the things at once. I focus on the handful that actually move the needle for my body and let the rest be.
That’s the part I want you to really hear. When your plan is built from your own chemistry, you do less and it lands harder. Less guessing, less white-knuckling, less money thrown at protocols that were never designed for you. Fewer, smarter moves. Bigger payoff. More fun.
My body isn’t clocking in at 29 because I got lucky. It’s 29 because I finally stopped guessing.
Now I know that I’ll never “look” like I’m in my 20s. I love following fitness influencers in their 50s and 60s and find them SO inspirational! But after losing 150# I’ll always have loose skin, even after a bit of cosmetic body work, and I’m ok with that. Lipidema is an ongoing connective tissue disorder that means I’m constantly managing my legs in particular, and even after having surgery to remove the fibrotic fat, my legs are a big point of acceptance.
But no matter what, I’d rather continue to have my longevity markers rankings top the charts, if I had to choose. Because that’s what I’m really doing this for, any of it. To continue to feel GOOD in my body for as long as humanly possible. Not through punishment, restriction, or micro-managing. But from a few simple strategies that help me work smarter.
If you’re in your 40s and doing everything right:
And your body still won’t cooperate, I want you to know the problem was never you. You’ve just been handed a generic plan for a body that was never generic.
Start with your blueprint. Body by Design® maps your 500+ markers and hands you the actual manual: what to eat, what to supplement, how to support your hormones, where your body needs backup. It’s the thing my clients come back to year after year, because your DNA doesn’t change, but everything you ask of it does.
I’m going to walk through exactly how this works over the next few posts, the DNA side and the peptide side both. If you want the full breakdown and the behind-the-scenes, that’s what I save for my paid subscribers inside LYFE Lab. Paid members get the full diary, the private member chat where I actually get specific with your questions, monthly live calls with me, and the Mixing Lab Peptide Calculator tool. Subscribe to annual and Biome Bootcamp (my anti-aging gut reset protocol) comes free; founding members get my PepSquad beginner peptide course on top. It’s where the reversal stops being a headline and starts being a plan.
You’re not falling apart. You’re not too late. You’re just getting started with better information.
Love,
Lindsey Strong
