Longevity Masters Show
Welcome to Longevity Masters - the place where midlife male entrepreneurs learn how to reverse their biological age and reclaim the strength, clarity, and power they thought they’d lost.
I’m Grant Hutchby, creator of The Turnback Time Machine, and my mission is simple:
To give successful-but-stuck entrepreneurs the tools to become young, happy & free. Not old, sad & trapped.
After hitting my own decline, I rebuilt my biology from the ground up.
Not with hacks. Not with hype. With rhythms, hormones, biology, and precision.
Now I teach the systems that restored my energy, sharpened my mind, and rebuilt my body.

Episode 50: Why Fat Loss Stalls After 40 | The Thyroid Hormone Most Men Ignore
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Stubborn fat after 40 is a discipline problem. They’re wrong.
In this episode of Longevity Masters, I break down the real driver behind energy, metabolism, and fat loss for male entrepreneurs: the thyroid.
The thyroid is your body’s metabolic sales manager.
It decides whether energy is spent or conserved.
When it’s working well, fat is converted into usable energy.
When it’s mismanaged, the body holds onto energy and progress stalls.
Most men respond the wrong way.
They train harder.
They eat less.
They push more stress into the system.
But chronic over training, poor sleep, and aggressive calorie restriction can actually suppress thyroid output and slow metabolism.
This isn’t a willpower problem.
It’s a management problem.
In this episode, I explain:
• Why thyroid function controls metabolic pace
• Why over training can stall fat loss
• Why cutting more calories often backfires
• The role sleep and recovery play in energy production
• Why resting heart rate is the best metric to track thyroid health
• How consistent routines improve metabolic rhythm
Your body works like a business.
Energy is revenue.
The thyroid is the sales manager that controls the flow.
Manage it properly and performance compounds.
Fix the rhythm.
Train with intention.
Recover properly.
Watch now. Then apply it.
