Most people think their metabolism slows because they’re getting older.
But the truth is far more measurable — and far more fixable.
Here’s what actually changes:
🔥 1. You lose metabolic tissue
Muscle is the most metabolically active tissue in the body.
After 35, strength declines unless it’s trained — meaning you burn fewer calories even at rest.
🧬 2. Cellular energy systems weaken
Mitochondria (your energy factories) decline in number and efficiency.
This reduces your ability to convert food → energy.
⚖️ 3. Hormones shift
Testosterone, growth hormone and thyroid hormones reduce gradually,
leading to slower calorie burn and reduced recovery.
⚡ 4. Chronic stress becomes the norm
Cortisol rises due to work, family, lack of sleep, and constant stimulation.
High cortisol increases fat storage and slows metabolism.
🧪 THE GOOD NEWS:
Every single one of these changes is reversible with the right testing and training:
✔ VO₂ & metabolic tests
✔ Strength development
✔ Better stress regulation
✔ Correct nutrition
✔ Proper sleep & recovery
