I Was 61 With the Metabolism of a 69-Year-Old. Here’s What Eight Months of Tiny Shifts Actually Did.

A real-numbers story about waking up late, starting anyway, and what the science of longevity looks like when it meets a real woman’s real life.

The machine did not lie to me. That was the problem.

I saw the Hume Body Pod advertised and thought it sounded interesting, useful even. I stepped on without much ceremony on a Tuesday morning, thinking I was roughly fine. Tired, yes. A little soft around the middle, sure. But sixty-one and fine. What came back was a different story: 163 pounds. Body fat at 34.6 percent. Metabolic age: 69.

I instantly hated the blessed machine.

I was eight years older, metabolically, than I was on paper. Eight years. I had managed to age a full decade ahead of schedule while sitting at my desk being very productive.

After the shock, I sat with the information. Not with shame, exactly, but with the particular clarity that arrives when data removes the option of soft self-deception. I had been meaning to do something about my health for several years. Meaning to is not the same as doing. What a wake-up call, delivered, as the universe apparently prefers, in a small room with fluorescent lighting.

That Tuesday became my line in the sand.

What Metabolic Age Actually Tells You

Before I get into what I changed, it is worth understanding what metabolic age actually measures, because it is not the depressing verdict it sounds like. It is, in fact, the most hopeful number I have ever seen on a report. Which is saying something, because I work in finance.

Metabolic age is derived from your basal metabolic rate, your muscle-to-fat ratio, your visceral fat, and your body water levels, then mapped against average values for people your chronological age. When your metabolic age is higher than your real age, it typically means you have less lean mass, more stored fat (particularly the dangerous visceral kind around your organs), and a slower-burning cellular engine than average for your peer group.

Translation: I had the metabolism of a woman who had given up. I had not given up. I had just been extremely busy giving up slowly, one twelve-hour workday at a time.

Here is the part that matters: you can change it. Unlike your birth certificate, metabolic age responds to behavior. That is the entire point.

I had spent years reading the research from people like Dr. Peter Attia (Outlive) and Dr. Casey Means (Good Energy) and feeling vaguely inspired and then returning to my desk for another twelve-hour workday. What the Body Pod did was convert abstract science into a personal number with my name on it. That changes things. Inspiration is optional. A number that makes you want to argue with a machine is not.

The Frameworks That Reframed Everything

I am not going to summarize two brilliant books in a paragraph. They deserve better than that, and frankly so do you. What I will tell you is the ideas that actually landed for me as a woman over sixty who sits at a computer most of the day, has arthritis in one knee, walks her dog more than a mile daily, and was, for a long time, genuinely fond of a glass of red wine at the end of the day. Several glasses, if we are being fully honest, which apparently we are.

From Peter Attia: The goal is not just to live longer. It is to maintain what he calls your Marginal Decade capacity, the ability to do the things that make life worth living well into your eighties and nineties. For me that image is specific: I want to be the grandmother who gets on the floor. Who goes on the trip. Who is not managing her limitations, but living past them. I did not do all of this so that I could spend my nineties watching from a chair.

Attia argues that the two most powerful levers for that outcome are VO2 max and muscle mass. Both decline with age unless you actively intervene. And both are measurable. That data-forward approach is what made his work click for a woman who manages spreadsheets for a living.

From Casey Means: The lens is cellular energy. When your mitochondria are working well, everything works better: your metabolism, your mood, your inflammation levels, your sleep. When they are not, the dysfunction shows up everywhere, often decades before a diagnosis names it. Her framework is not about restriction. It is about information. Food is data. Movement is data. Sleep is data. What does your body do with it?

What my body was doing with it, apparently, was filing it under “problems for future Susie.” Future Susie would like a word.

The practical intersection of both frameworks, for women over fifty specifically, comes down to this: muscle is your metabolic savings account, and most of us have been spending it for years without depositing.

What I Actually Changed (And What I Did Not)

I want to be clear about something before I list the shifts. I did not overhaul my life. I did not start training for two hours a day. I did not eliminate entire food groups or embrace any diet that requires a laminated card to explain at a restaurant. I have a full-time career managing finance across a portfolio of companies. I have a husband recovering from multiple surgeries. I have a flock of backyard chickens who treat my schedule with complete indifference. I have a life with real demands.

What I did was identify the highest-leverage small changes and stack them in order of impact. Kintsugi thinking, if you are familiar with the Japanese art of repairing broken pottery with gold: not fixing perfection, but making the cracks part of the beauty. Incremental, sustainable, honest. Also deeply satisfying for those of us who are constitutionally incapable of doing everything at once anyway.

Here is the actual sequence:

Month One: Protein and the Morning Anchor

I built a non-negotiable morning: water immediately on waking, a protein shake with grass-fed milk and collagen within thirty minutes, supplements (D3/K2, CoQ10, omega-3, turmeric), and ten to fifteen minutes of red light therapy with meditation before I opened my laptop.

That was it for month one. No dramatic dietary changes. Just that sequence, every day.

The protein piece is not trivial. Research is consistent that women over fifty are chronically under-eating protein, and protein is the primary input for maintaining lean muscle mass. I targeted a gram per pound of body weight. Hitting that number required intentionality, particularly because I am not someone who eats meat at every meal. I used Cal AI to track my food and discovered, with some embarrassment, that I had been eating approximately half the protein I thought I was. I am a CFO. I track everything. Apparently not that.

Month Two: The Wine Conversation

I had a real conversation with myself about wine. Not a dramatic one, not a guilt spiral. Just an honest one between me and my Apple Watch, which had been quietly generating data about my sleep quality that I had been successfully ignoring.

A glass or two of red wine most evenings had become a decompression ritual. It was also disrupting my sleep architecture, elevating inflammation markers, and interfering with fat metabolism overnight. My watch knew this. My bloodwork knew this. I was, as it turns out, the last to know.

I did not give it up forever. I did Dry January and later Dry April, both as experiments rather than proclamations, because proclamations in my experience are for people who have not met themselves yet. The bloodwork results before and after those alcohol-free windows told me most of what I needed to know. I will say this: I did not miss the wine as much as I thought I would. I did miss the ritual, which is a very different problem with a much cheaper solution.

Month Three: Walking With Intention

I already walked my dog Roo more than a mile daily. Roo is a Shorkie Poo with extremely strong opinions about squirrels and a pace that can generously be described as “exploratory.” What I added was awareness: I wore a continuous glucose monitor (CGM) for ninety days, and I discovered that a ten-to-fifteen minute walk after meals dropped my post-meal glucose curve measurably. So I did that. Still not a marathon, still the same dog, still the same squirrels. Just intentional timing.

A 2025 study confirmed that walking in spans of at least ten minutes, rather than scattered steps throughout the day, had the biggest impact on mortality and cardiovascular disease outcomes. I was already doing the volume. I just structured it differently. This is, in retrospect, a very on-brand discovery for a woman who manages portfolio companies: turns out sequencing matters as much as quantity. Who knew.

Months Four Through Six: Zone 2 Cardio

Here is where my right knee complicated things. My arthritis means I cannot walk at a pace high enough to reach Zone 2 heart rate, which is the aerobic training zone (roughly 114 to 133 BPM for me) that builds mitochondrial density and cardiovascular capacity. Walking Roo counts as Zone 1. It is lovely and it matters, but it is not the same. Roo, for his part, is deeply committed to Zone 1 and sees no reason to renegotiate.

The solution was a rowing machine. Low-impact, knee-friendly, and genuinely effective for Zone 2 work. I built up slowly: twenty-minute sessions three times a week, progressing to forty minutes over four weeks. I will be honest with you. The first few sessions I watched the clock like I was serving a sentence. By week six, I was watching Netflix. Progress takes many forms.

Not every week was perfect. That is fine. The Hume Band tracks my daily movement and body metrics between Body Pod scans, which helped me stop pretending that a busy week meant my body had somehow paused the aging process. It had not.

Months Six Through Eight: Resistance Training

This is the piece I resisted the longest, which is ironic given that it is literally called resistance training, and the one that in retrospect I should have started first.

Lean mass is the metric that moves metabolic age. You can optimize everything else and plateau if you are not preserving and building muscle. I built a protocol around a Smith machine in the room my son vacated when he moved into his own apartment. He is thriving. I immediately converted his room into a gym. We are both happy.

The protocol: glutes and hamstrings one day, shoulders and core another, a full-body metabolic circuit on the third. Forty-five seconds on, fifteen off. Knee-conscious throughout. There is something deeply satisfying about lifting weights in a room that used to contain a twenty-six-year-old’s gaming setup. I choose to see it as a metaphor.

The key insight from both Attia and Means is that muscle tissue is metabolically active even at rest. More of it means a faster baseline burn, better glucose uptake, and lower insulin resistance. It is the compound interest of the wellness world. And as a finance person, compound interest is the only argument I ever needed.

The Numbers, Eight Months Later

Metabolic age from 69 to 61 in eight months. Not through suffering. Through sequence.

I no longer hate the machine. We have an understanding.

My goal for my July birthday is metabolic age 55. The machine and I have a date.

What I Wish Someone Had Told Me at the Start

You do not need to do everything at once. The research on habit formation is clear: stacking one new behavior successfully is more durable than attempting five simultaneously and abandoning all of them before February. Start with protein. Add the walk timing. Build from there.

Data is not judgment. The Body Pod number was not an accusation. It was information. Get the information, even if your first instinct is to argue with it in the parking lot, audibly.

The “it’s too late” voice is wrong, and the science says so. Sarcopenia, which is muscle loss, accelerates after fifty, but it is not inevitable and it is absolutely reversible. Studies have shown that women who were entirely sedentary were able to gain meaningful function through resistance training tailored to their current ability. The window is open far later than most of us believe. We have simply been told otherwise long enough that we stopped questioning it.

Alcohol is the quiet saboteur. I am not anti-wine. I am pro-information. If you are doing most things right and not seeing results, the evening glass is the first place I would look. The data will tell you what you need to hear. Whether you listen is between you and your Apple Watch.

Your why has to be concrete. “Feeling better” is not a why. Mine is: I want to be physically present for the generations of people I love, well into my nineties. Not watching from the sidelines. Not managing my limitations. There. That specific. When I picture that image on the days when nothing else works, it moves me off the couch every time.

The Starter Stack: Where to Begin

If you are standing where I stood in September 2025, probably at a machine you are currently resenting, here is the sequence I would give you. Not all at once. In order.

Weeks one and two: Set a protein target (0.8 to 1 gram per pound of body weight) and hit it. Use a food tracking app for two weeks so you understand what you are actually eating. I like Cal AI, super easy, take a picture of your plate and it does the rest. Most women are consuming half what they need, which comes as a genuine shock to women who thought they were eating pretty well. I was one of those women.

Weeks three and four: Build a morning anchor. Water, protein, one non-negotiable ritual before screens. Ten minutes counts. You do not need a perfect morning routine. You need a consistent one.

Month two: Add intentional post-meal movement. Ten to fifteen minutes after your largest meal. Walk, march in place, whatever is accessible. If you have a dog, congratulations. You already have an accountability partner with no sympathy for rest days.

Month two onward: Consider a CGM for ninety days. Seeing your glucose curve respond to food and movement in real time is the most motivating biofeedback tool I have found. Nothing motivates a behavior change quite like watching a number spike in real time and knowing it was the crackers.

Month three: Identify your Zone 2 vehicle. Walking works for most people. Rowing, cycling, and elliptical work for those with joint issues. Target three to four sessions per week, building from twenty to forty minutes. Start where you are. The machine does not care about your starting point, only your direction.

Month three and beyond: Add resistance training. Two to three sessions per week. You do not need a gym. You need progressive load, consistency, and the willingness to feel slightly ridiculous for the first few weeks. That part passes.

A Note on the Books

Both Outlive by Peter Attia and Good Energy by Casey Means are worth reading in full, not because you will implement everything (some recommendations are genuinely extreme and I will not pretend otherwise), but because understanding the why behind the habits makes the habits stick. When you understand that resistance training is literally protecting your brain from cognitive decline as much as it is shaping your body, you show up differently. When you understand that your evening wine is raising your hsCRP while you sleep, the information becomes its own argument.

Read them. Dog-ear the pages. Argue with them a little. That is healthy too.

The Honest Part

I am still in progress. My VO2 max has a long way to go. There are weeks when work swallows everything and the rowing machine sits in the corner looking reproachful. The fundamentals still hold on those weeks: water, protein, the morning sequence. That is the foundation. Everything else builds on it, and everything else is allowed to be imperfect.

What I know for certain is that the woman who stepped into that Body Pod in September 2025 and the woman writing this in 2026 are not the same person, metabolically or otherwise. The number told me the truth. And the truth turned out to be the most useful gift I received all year, even if I did spend the first week complaining about it to all who would listen.

The machine was right. I am glad I listened.

P.S. By the time this article published, my metabolic age had ticked back up to 62. Curtis has a major surgery coming and my cortisol knows it. That is how this works. The number moves with your life. The habits are what bring it back.
