Reclaim Your Energy, Metabolism, and Vitality After 40
Science-backed nutrition, fasting, and fitness protocols — designed specifically for the hormonal and metabolic reality of your body after 40, not recycled advice built for 25-year-olds.

"Your body after 40 isn't broken — it's just running on instructions written for someone half your age, and it's time we fixed that."
— THOMAS HARMON

What you'll learn
What you'll be able to do
- Design a personalized low-carb meal plan that stabilizes blood sugar, reduces inflammation, and supports healthy weight at your specific life stage
- Implement an intermittent fasting protocol — and progress to therapeutic extended fasting — safely and effectively for your gender and hormonal profile
- Select and stack evidence-based nutritional supplements targeting longevity, energy, and metabolic health for people over 40
- Follow a gender-specific resistance and cardio exercise program that preserves muscle mass, supports bone density, and boosts longevity markers
- Identify natural therapies and lifestyle interventions (breathwork, cold exposure, sleep optimization) that complement your fasting and nutrition protocol
- Track key biomarkers and self-assessments to objectively measure your progress and adjust your personal longevity plan over time

Who it's for
Is this you?
The Perimenopausal Woman
She's navigating hormonal shifts, unpredictable energy, and stubborn weight gain and needs strategies built specifically for her changing biology — not generic advice.
The Man Losing His Edge
He's noticed the muscle getting softer and the energy getting flatter and wants a science-backed protocol — fasting, low-carb, resistance training — calibrated to testosterone decline and midlife metabolism.
The Longevity-Minded Woman
She's less interested in quick fixes and more focused on adding healthy, vital years — and wants to understand biomarkers, autophagy, and the lifestyle levers that actually drive longevity.
The Metabolic Health Seeker
Blood sugar is creeping up, inflammation feels chronic, and he wants evidence-based tools — berberine, low-carb eating, fasting protocols — to reverse the trend naturally before it becomes a diagnosis.
The Returning Exerciser
She stepped away from consistent fitness and wants to return safely — with a gender-specific program that respects her recovery needs, protects her bones, and actually fits midlife life.
The Biohacker Over 40
He's already experimenting with cold exposure, supplements, and fasting but wants a structured, credentialed framework to stack these tools intelligently and track real results.

THOMAS HARMON
If you're reading this, I'd guess something has shifted in the last few years — and not in the direction you wanted. Maybe the scale crept up despite eating the way you always have. Maybe your energy stopped being reliable. Maybe you're sleeping but not recovering, working out but not seeing results, or just feeling like your body is working against you in ways it never used to.
I hear that constantly from people in their 40s and 50s. And the frustrating part isn't that the changes are happening — it's that the advice available to most people completely ignores them. The fitness content is built for 25-year-olds. The nutrition advice doesn't account for perimenopause or testosterone decline. The fasting protocols don't distinguish between a cycling woman and a 52-year-old man. And nobody is talking about the biomarkers that actually tell you whether any of this is working.
That gap is exactly why I built Thrive Past 40. Everything in this school is designed around the biology and lived experience of midlife — the hormonal shifts that change how you store fat and build muscle, the metabolic slowdown that doesn't respond to calorie restriction the way it used to, and the real, evidence-based tools that work with your physiology rather than against it. Low-carb nutrition calibrated to your hormonal profile. Fasting protocols that account for gender differences in safety and benefit. A supplement stack anchored in longevity science — not influencer trends. Exercise programming built around muscle preservation, bone density, and sustainable performance. And the lifestyle medicine layer — sleep, cold exposure, breathwork, gut health — that multiplies everything else.
I want to be straightforward with you: this isn't a 30-day transformation program. It's a complete operating system for the second half of your life, built on science, practical application, and deep respect for what you're actually navigating. You're not broken. Your approach just hasn't caught up with your biology yet. That's exactly what we fix here.
If you're ready to stop following advice that wasn't built for you — and start working with a plan that genuinely is — I'd be glad to have you inside Thrive Past 40. Let's build your longevity baseline and get to work.
