Reversing My Biological Age

Karmel Franklin·September 5, 2026
Reversing My Biological Age

Aging isn't the enemy — metabolic decline is. The full framework I personally use to reverse my biological age: muscle, NAD and mitochondrial health, targeted peptides, removing the accelerators of aging, precision nutrition, signaling, and daily inflammation control.

I want to be honest about something up front. Aging itself is not what I am afraid of.

What I am interested in is the gap between the number of birthdays I have had and the way my body is actually functioning underneath — my biological age. And here is the part that changed everything for me: biological age is not a fixed number. It is shaped by measurable things — inflammation, insulin sensitivity, muscle mass, mitochondrial function, sleep quality, body composition, even how my skin and hair are behaving. Those things respond to how I live.

I am not interested in accepting decline simply because another birthday happened.

I care about function. How strong I am. How I recover. My energy. My metabolic health. My body composition. My skin, my hair. How the whole system is running. That is the conversation I want to be in — not chasing a younger number on a test, but building a body that keeps performing at a level I refuse to let slip.

The New Conversation Around Aging

For a long time, “anti-aging” meant creams, cosmetic tweaks, and hoping nobody noticed. The modern longevity conversation is much bigger than that.

We are now looking at muscle and metabolic health. Mitochondrial function and cellular energy. Chronic inflammation. Sleep and recovery. Nutrition quality. Cellular signaling. We are measuring how the body is actually working underneath the surface, and then we are influencing those systems on purpose.

That is the shift — from hoping aging is kind to actively shaping the way your body ages. It is also the setup for everything that follows. The seven sections below are the framework I personally use, and none of them lives in isolation. Muscle affects metabolic health. Sleep affects recovery. Nutrition affects your ability to maintain muscle. Cellular energy matters to performance. Stress affects sleep. The peptide is not the entire protocol. Longevity is a system.

1. Muscle Is Longevity Insurance

Muscle mass naturally declines with age unless you actively maintain it — and that decline is associated with reduced metabolic rate, increased insulin resistance, and higher mortality risk. Muscle is not only about how you look. It supports physical function and independence, and it is closely connected with metabolic health. Resistance training also supports bone and physical capacity as we age.

So I train like it matters, because it does. Progressive resistance. Weighted, strength-focused movements. Consistent movement every day. Adequate protein to actually maintain the muscle I am asking my body to build.

I train because I want to look strong and sculpted — and I train because I want a body that is still performing at an elite level decades from now. The same work that shapes me now is the work that keeps me standing, moving, and capable later. That is the real reason this is section one.

Muscle isn’t about aesthetics. It’s about survival and metabolic resilience.

2. I Protect NAD and Mitochondrial Function

NAD+ is a coenzyme involved in cellular energy metabolism, redox reactions, and processes involved in cellular maintenance. NAD+ levels decline as we age — starting as early as your twenties. Mitochondria are central to energy production, so this part of longevity matters to me because I care about maintaining energy, recovery, and cellular function rather than waiting until I feel depleted to think about it.

I also support this pathway with MOTS-c, a mitochondrial-derived peptide being studied for metabolic and cellular signaling. I describe it accurately: it is being researched for metabolic regulation and mitochondrial resilience, not presented as a guaranteed human anti-aging outcome.

When these systems are compromised, the body reflects it — lower energy, slower recovery, impaired cellular repair. When they are supported, you feel that too. This is why I pay attention to mitochondrial health long before there is a problem to fix.

3. I Use Targeted Peptides to Support Specific Systems

Once the foundation is in place, I layer in peptides that target very specific functions. The key philosophy here is that I do not believe in taking everything at once, forever. I use targeted compounds according to the specific goals I am working on, and my plan is customized and adjusted through Luxury Medical Group.

Targeted does not mean “take more.” It means having a reason for everything that is there.

Metabolic and body-composition support. Compounds used around metabolic health, inflammation, and body composition — not extreme weight loss, but a more efficient, less inflamed baseline. Someone focused here is usually working toward how their body composition and metabolic function are aging.

Reproductive and hormonal signaling. Compounds that support the body’s natural hormone signaling rather than overriding it. This is relevant when hormonal balance, cycle regularity, or reproductive health are part of the conversation.

Regenerative and beauty support. Compounds studied for tissue repair, skin, and hair pathways — the layer of the conversation that shows up in the mirror. Someone focused here is usually working on skin quality, recovery, and the visible side of aging.

Antioxidant support. Compounds that support the body’s antioxidant defense and detox pathways, reducing oxidative stress — one of the biggest drivers of aging, internally and externally.

Longevity-focused signaling. Compounds being studied for cellular health and longevity pathways over time — the long-game layer of the plan.

Some of these compounds are investigational and not FDA-approved for an anti-aging indication, so I never present them as approved anti-aging treatments. This is a personalized, supervised plan, not a shopping list.

Every part of my protocol has a job.

I’m not trying to build the biggest stack. I’m trying to build the smartest one for the version of my body I’m trying to create.

4. I Remove Accelerators of Aging

Longevity is not only about what you add. It is also about what you stop repeatedly doing to your body. Chronic sleep deprivation, smoking, excessive alcohol, poor diet quality, inactivity, and living in a constant high-stress state all accelerate the same systems I am trying to protect.

I do not say this to be preachy. I frame it as removing unnecessary friction from the system. The body ages faster when it is inflamed, under-recovered, undernourished, and over-stressed. Remove the friction, and everything else you are doing works better.

The alcohol and sleep piece is worth calling out because it creates such a stark contrast with the expensive longevity world. Someone can spend enormous amounts on supplements, peptides, and technology while repeatedly undermining recovery with a few glasses of wine and five hours of sleep. That contradiction is real — and it is one of the fastest places to make a change that costs nothing.

Alcohol disrupts deep sleep and increases inflammatory markers. Sleep restriction alone has been shown to impair insulin sensitivity within days. So I removed what speeds decline. That is strategy, not deprivation.

5. Precision Nutrition (Not Diet Culture)

I am not interested in crash diets or obsessively eating less and less. I care about giving the body what it needs to maintain muscle, energy, healthy skin, metabolic function, and recovery.

I follow a Mediterranean-style whole-food pattern because it is one of the most studied dietary patterns associated with cardiovascular and metabolic health: extra-virgin olive oil rich in polyphenols like hydroxytyrosol, wild fish, high-quality protein, leafy greens and vegetables, fiber, and polyphenol-rich plant foods. Healthy fats, color, and quality — without making eating feel like a punishment.

Food is information. It signals your biology.

I want to be very clear about this: I want to look lean and sculpted, but I am not willing to destroy muscle and vitality trying to make a number on the scale smaller. Eating enough of the right things is part of the longevity plan, not the opposite of it.

6. Strategic Signaling Support

Peptides are signaling molecules — short chains of amino acids that direct specific functions in the body. What fascinates me is that different signaling pathways relate to very different functions: metabolism, recovery, tissue repair, hormonal signaling, cellular maintenance. Aging is not one single “signaling problem,” and I do not treat it like one.

I use targeted signaling strategically and cycle things according to my personalized plan rather than assuming everything belongs in my routine permanently. The body changes. My goals change. The plan has to be able to change with them.

7. Daily Inflammation Control

There is a concept often called “inflammaging” — persistent, low-grade inflammation associated with aging and age-related disease. It is one of the strongest drivers of accelerated biological aging, and it is something I work on daily rather than waiting for it to show up in labs.

Most of my inflammation control is the same lifestyle pieces already discussed here: sleep, strength training, food quality, stress management, morning and outdoor light, and recovery. Red-light therapy is part of my routine too — I use it for skin and circulation support, not as a universal cure for inflammation.

Inflammation shows on your face before it shows in labs.

The Proof

I reversed my biological age by 13 years — in two.

Two years ago I decided to measure, not guess. The biological-age assessment I took came back reading 26 years and 10 months — 13 years and 7 months younger than my calendar age.

I am not claiming any single test is a perfect measurement of literal aging. This is one result from the biological-age assessment I took, inside my personal story — the outcome of measuring, then optimizing with precision rather than guessing. That is what becomes possible when you stop experimenting blindly and start treating the body as a system.

The Real Goal

I did not get interested in longevity because I am afraid of birthdays. I became obsessed with it because I realized how much agency we have over the way we care for the body we are going to live in for the next several decades.

The goal is not simply to live longer. I want the muscle, the energy, the skin, the hair, the metabolic health, the strength, the recovery, the brain — the body that still feels like mine. And I want to build that now, instead of waiting until something starts failing to care about it.

This entire system is why I think differently about aging. I am not relying on one peptide, one supplement, or one beauty treatment. I am creating an environment that supports the version of myself I want to keep becoming — and the peptide is not the entire protocol. The system is.

Welcome to the Ageless Era. Because what gets measured, gets optimized.
