The Truth About Aging PART 4: ENERGY CRASHES

We should all mimic fine wine by getting better with age. —-GP

You wake up tired. Coffee barely helps. By 3 PM, you're crashing hard.

This isn't normal "aging." It's your mitochondria (your energy factories) breaking down, your heart pumping less efficiently, and your hormones abandoning ship. The good news? You can fix it.

Why You're Running on Empty

1. Your Mitochondria Are Dying

- After 40, these cellular batteries decline by 10% per decade

- Result? Less ATP (energy molecules) = chronic fatigue

2. Your Heart Isn't Keeping Up

- Cardiac output drops 20-30% by 70

- Stiff arteries force your heart to work harder for less

3. Hormonal Freefall

- Thyroid slows→ metabolism drags

- Testosterone/estrogen drop→ less vitality

- Insulin resistance spikes→ energy crashes after meals

4. The Sleep Steal

- Deep sleep decreases 60-70% between ages 20-60

Without it, you can't repair cells or clear brain toxins

How to Fight Back

1. Train Like a Hunter (Not a Hamster)

- Stop chronic cardio (it burns out mitochondria)

- Do short, intense bursts (sprints, kettlebell swings) 2x/week to boost mitochondrial growth

2. Eat for Steady Energy

- More fat, less sugar (fat burns cleaner without crashes)

- Time carbs (eat them around workouts when muscles can use them)

- Try MCT oil (instant mitochondrial fuel)

—Veggies are key, you can never get enough leafy greens

3. Hack Your Heart

- Zone 2 training (brisk walking where you can talk but not sing)

- 4-6 sessions/week of 30-45 mins reverses arterial stiffness

4. Fix Your Sleep (For Real)

- Wear blue blockers after sunset

- Keep bedroom at 65°F (cool temps boost deep sleep)

- Try magnesium glycinate before bed

The Bottom Line

Fatigue isn't inevitable. Your energy systems want to work– they just need the right signals. The difference between needing a nap after lunch and feeling sharp all day comes down to these upgrades.
