The metabolic health space is having a moment—and rightly so. With chronic conditions surging and mainstream medicine lagging in prevention, a new wave of thinkers, biohackers, and scientists is helping us rethink what it means to be metabolically optimized. They’re not all cut from the same cloth, but each offers a lens on human performance worth watching.

Here are seven of the most influential voices reshaping the metabolic conversation today.

1. Bryan Johnson – The Full-Stack Biohacker

No list is complete without Bryan Johnson—the entrepreneur-turned-protocol-pioneer behind the Blueprint Project. With his team of researchers and physicians, Bryan is building a quantified, data-driven playbook for reversing biological age. His mission is clear: prove that aging can be slowed—if not reversed—through rigorous metabolic inputs, from fasting and blood biomarker tuning to light, sleep, and exercise optimization.

Why we pay attention: Johnson treats metabolic health not as a side effect of longevity—but as the lever. Whether you agree with his aggressive protocols or not, he’s reframing what’s possible.

2. Gary Brecka – The 10X Clinical Edge

A former mortality analyst and co-founder of 10X Health, Gary Brecka’s work blends lab-driven precision with street-level simplicity. He emphasizes oxygen utilization, genetic methylation pathways, and core metabolic regulators like vitamin D, testosterone, and inflammation. Brecka’s focus is on getting people to feel noticeably better, fast—through protocols grounded in measurable deficiencies.

Why we pay attention: Gary bridges a critical gap—turning esoteric labs into real-world action. His language is clear, his interventions practical.

3. Andrew Huberman – The Systems Thinker

Neuroscientist and Stanford professor Andrew Huberman has become a go-to voice in the health world—not for quick fixes, but for his rigorous, systems-level understanding of how the brain and body interact. Though best known for his insights on neuroplasticity and performance, Huberman consistently integrates metabolic levers into the conversation—from circadian biology to nutrient timing and cold exposure.

Why we pay attention: Huberman brings academic precision to bio-optimization. He gives metabolic health a cerebral upgrade—and makes the science accessible.

4. Dave Asprey – The OG Biohacker

Love him or question him, Dave Asprey helped start the conversation. Founder of Bulletproof and one of the earliest promoters of ketones, mitochondrial health, and anti-aging through metabolic tuning, Asprey’s work catalyzed a generation of self-experimenters. He’s since moved into spiritual and cellular health, but his metabolic roots run deep.

Why we pay attention: Dave understood early on that metabolism isn’t just about weight—it’s about energy, clarity, and control.

5. Dr. Gabrielle Lyon – Muscle as Metabolic Currency

A functional medicine physician and founder of the “muscle-centric medicine” movement, Dr. Lyon reframes muscle as the organ of longevity. She argues that building and maintaining skeletal muscle is one of the most overlooked drivers of metabolic health—affecting everything from insulin sensitivity to mitochondrial function.

Why we pay attention: She’s shifting the conversation away from fat loss to functional metabolism, grounded in strength, amino acids, and anabolic balance.

6. Ben Greenfield – The Holistic Optimizer

Ben Greenfield blends physiology, spirituality, and ancestral health into a potent mix. He’s experimented with everything from continuous glucose monitors and NAD injections to breathwork and fasting-mimicking diets. While some of his methods may stretch the average protocol, he’s a prolific voice in the intersection of metabolic health and total-body resilience.

Why we pay attention: Ben constantly asks: what else is influencing metabolism—from emotions to electron flow? He’s unafraid to go deep.

7. Peter Attia – The Tactical Longevity Strategist

A physician and best-selling author, Peter Attia delivers one of the most structured views on metabolic health and lifespan extension. He focuses heavily on the “four horsemen” of chronic disease—heart disease, cancer, neurodegeneration, and metabolic dysfunction—and offers a comprehensive toolkit that includes zone 2 cardio, fasting, strength training, and continuous monitoring.

Why we pay attention: Attia balances data with pragmatism. His work helps separate what’s interesting from what’s essential.

What These Influencers Share

Each of these voices brings a distinct philosophy, but they share key principles:

• A data-first approach to tracking and adjusting health inputs.

• A belief that metabolic health is upstream of nearly every chronic issue.

• A commitment to empower individuals, not just treat symptoms.

At Better Life Protocols, we see metabolic optimization not as a luxury, but a baseline. It’s the foundation from which energy, clarity, and long-term vitality are built.
