We’ve been told to eat three meals a day since we could walk.

Somewhere along the way, snacking became a sport.

And skipping breakfast? Practically taboo.

But here’s the twist:

Some of the world’s leading longevity experts are doing exactly that—skipping meals, shrinking eating windows, and letting their bodies go longer without food.

Not to starve.

But to heal.

It's called intermittent fasting, and it's not a trend—it’s a return to how our bodies are wired to thrive.

The Problem: We're Eating Too Often, and Our Bodies Never Get a Break

Let’s be honest. Most of us eat constantly. Morning smoothies, afternoon lattes, a little something before bed.

Every bite signals your body to shift into digestive mode. Insulin spikes. Energy dips. Over time, metabolism slows and inflammation rises—a dangerous combo that accelerates aging from the inside out.

According to Dr. Valter Longo, a leading researcher in aging and cellular regeneration, prolonged periods without food allow the body to clean house.

It’s called autophagy—your cells recycle waste, reduce inflammation, and trigger protective mechanisms that promote longevity.

Translation?

Fewer aches. Better energy. A body that actually feels younger.

The Solution: Shrink Your Eating Window, Not Your Life

You don’t need to fast for days or adopt some monk-like discipline.

In fact, one of the most powerful (and sustainable) approaches is incredibly simple:

The 16:8 Method.

Here’s how it works:

• You fast for 16 hours (yes, sleep counts).
  
  
• You eat all your meals within an 8-hour window—say, 12pm to 8pm.
  
  
• You repeat daily or a few times a week, depending on your goals.

Your coffee’s still allowed (black or with a splash of cream).

You’ll hydrate, move your body, and—shockingly—you might not even feel hungry after a few days.

“Fasting helped me drop 10 pounds, but what surprised me most? My brain fog vanished. I feel sharper in my 50s than I did in my 30s.” — Julie M., 52

Your Beginner’s Guide to Getting Started (Without Going Crazy)

Starting anything new can feel overwhelming—especially when food’s involved.

Here’s how to ease into intermittent fasting without the hanger headaches:

🕐 Use the Zero App to Track Your Fasts

Zero makes it stupidly easy to log your fasting and eating windows. You’ll get nudges, progress charts, and even expert-led guidance to stay on track.
(And there’s something weirdly satisfying about seeing your “fasting streak” grow.)

💧 Hydrate Like It’s Your Job

Most people mistake thirst for hunger. During your fast, aim for at least half your bodyweight in ounces of water daily.

Pro tip: Add Liquid I.V. to your water once a day—it’s an electrolyte powerhouse that helps you stay energized and curb cravings (especially when you’re just starting out).

🧂 Add Sea Salt to Your Morning Water

A pinch of high-quality salt can support electrolytes and prevent dizziness or fatigue as your body adjusts.

💤 Expect (and Respect) the Adjustment Period

The first few days? They might be uncomfortable.

But most people report feeling more alert, more energized, and less hungry after the first week. Your body wants to adapt—it just hasn’t been given the chance.

What Intermittent Fasting Really Does for Your Longevity

Still not convinced? Let the data speak.

• Improves insulin sensitivity (lower risk of type 2 diabetes)
  
  
• Reduces chronic inflammation (a root cause of aging and disease)
  
  
• Boosts human growth hormone (HGH) levels (linked to fat burning and cellular repair)
  
  
• Triggers autophagy (your body’s own detox and repair system)
  
  
• May extend lifespan in animal models by up to 30%
  
  
• Promotes mental clarity, better sleep, and lower stress hormones

It’s not magic. It’s metabolic intelligence—unlocking a biological rhythm we were designed to follow.

The Bottom Line: Eat Less Often, Live More Fully

Intermittent fasting isn’t a diet. It’s a rhythm. A shift.

It asks one simple question: What if you gave your body more time not to eat?

You might just give it more time to live.

So here’s your gentle nudge:

🕐 Download Zero.
💧 Order some Liquid I.V.
🍽 Pick your first 8-hour eating window.

Then watch what happens.

Because the next time someone tells you skipping breakfast is unhealthy, you’ll know better.

You won’t just be fasting.

You’ll be aging backwards.
