Why Your Doctor Should Be Recommending Fasting

Let’s Talk About What’s Missing in Medicine

If you’ve ever left your doctor’s office with more prescriptions than solutions, you’re not alone.Our current medical system is brilliant at crisis care, but not at prevention.

What if one of the most powerful healing tools we have isn’t a pill, but a practice that’s been built into our biology for millions of years?

That tool is fasting.

Fasting Is Not a Trend — It’s Human Design

Fasting isn’t about restriction. It’s about restoration.

Our ancestors thrived through cycles of feast and famine that activated deep repair mechanisms in their cells. Today, constant eating keeps those healing pathways switched off. When you stop eating for certain periods of time, you don’t shut your metabolism down, you wake it up.

Your body moves from burning sugar to burning fat for fuel. In this state, it produces ketones, which aren’t just energy; they’re messengers that improve focus, brain health, and longevity.

The Science Doctors Can’t Ignore

In 2016, cell biologist Dr. Yoshinori Ohsumi won the Nobel Prize in Physiology or Medicine for discovering autophagy — your body’s self-cleaning process. During fasting, your cells recycle damaged parts, eliminate toxins, and regenerate stronger versions of themselves.

No medication can do that. And it doesn’t stop there.

Dr. Valter Longo, director of the USC Longevity Institute, found that fasting for as little as three days can reset the immune system, regenerating new white blood cells while clearing out old ones. His research also shows improvements in insulin sensitivity and inflammation — two of the biggest drivers of chronic disease.

A Free, Evidence-Based Prescription for Metabolic Health

Imagine if your doctor could write this on a prescription pad:

“Fast for 13–16 hours daily, drink water, and eat real food in your eating window.”

That simple practice can:

• Lower blood sugar and insulin resistance

• Reduce inflammation

• Improve energy and mental clarity

• Support hormone balance

• Activate cellular repair through autophagy

Research in The New England Journal of Medicine shows that intermittent fasting improves brain-derived neurotrophic factor (BDNF), a protein essential for memory and learning (PubMed ID: 24275554).

Another study published in Cell Metabolism found that fasting positively changes the gut microbiome, increasing beneficial bacteria like Akkermansia muciniphila, which supports neurotransmitters that regulate mood and focus.

Why Most Doctors Aren’t Talking About This

Medical training rarely includes nutrition — let alone fasting physiology. So many doctors simply aren’t aware of how powerful this tool can be.

Yet, as research continues to grow, fasting is emerging as one of the most effective and accessible ways to reverse metabolic disease — without side effects, prescriptions, or high costs. If fasting were a drug, every physician would prescribe it.

The Call to Action: Let’s Bring Fasting Into Healthcare

It’s time for the medical community to evolve.

Instead of only prescribing what to eat, we also need to guide when to eat. Even short daily fasts can reduce oxidative stress and improve cholesterol (PubMed ID: 32828761). Longer fasts — like a three-day water fast — can stimulate stem-cell regeneration and strengthen the immune system.

As I often remind my Resetters:

“Your body is not broken. It’s brilliant. You just have to get out of its way.”

Final Thoughts

When you fast, you’re sending your body a message:“I trust you. I know you can heal.”

Doctors who embrace fasting aren’t just adding another tool to their toolkit, they’re joining a revolution in healthcare that honors the body’s natural intelligence.

From the bottom of my heart, I hope this helps. 💛
