I didn’t eat for 3 days


More American’s have run a full marathon than have completed a 3 day fast. I was surprised to find it easier than I’d imagined. I attribute this to my practice of intermittent fasting weekly for the past 3 years.

As the healing miracles continue to be revealed in the research of fasting, I had to try it out myself. Most attractive to me was the promise of DNA repair, cellular autophagy (consuming damaged cells), and creating my own stem cells. Some people spend up to $30,000 on stem cell therapy. We have our own internal, built-in pharmacy and can use fasting to regenerate stem cells for free! See geeked out research article excerpts below.

From Thursday night to Sunday night, I drank only water and black coffee. I took a couple capsules of magnesium and potassium each day as well as a small amount of pink himalayan sea salt. Nothing else!

I felt my worst end of day 2 and felt my best end of day 3. I kept up with my daily routine of hot and cold exposure by way of infrared sauna and cold plunge ice bath. My breathwork routine felt wonderful as always and really took the edge off if I started to feel like a headache might be coming. I treated 45 patients over the first 2 days of fasting. I was worried about running out of gas at the office on day 2 and felt that if I could make it past that point, the home stretch on a lazy Sunday would be fine.

The most trying temptations came during the cutting of the pizza for my children on Friday night, and the peeling of apples for them on Saturday afternoon. I slept great night 1 and poorly night 2. I was tossing and turning through the nightmare that I’d eaten one of those beautiful apples, ruining the 3-day streak early. I felt ashamed and upset with myself for not making it as long as I had targeted. What a relief to find upon waking that it wasn’t true.

I tried a urinalysis on Sunday night and found ketones as predicted. This told me that my body had successfully adapted to ketosis to burn fat as fuel instead of carbs. I weighed in on Sunday night down 6 pounds and again on Monday night back up 10 pounds! Now I have a only a slight idea of what my MMA patients have to go through regularly during weight cuts in preparation for fights. 

After a glorious meal Sunday evening, I woke up Monday feeling pretty groggy. After the fog lifted, I felt refreshed, motivated, excited and proud to have accomplished the challenge. One of my favorite osteopaths, Dr. Joseph Mercola, practices prolonged fasting once every quarter to reap the amazing benefits.

The challenge of fasting can be described as “homeodynamic eustress” or good stress. Similar to the good stress that is induced when we exercise. By exposing the human body to these challenges, it becomes stronger. We can sometimes over-train with exercise and cause more harm than good. The same is true of fasting.

Some benefits of prolonged fasting include:

1. Promotes Blood Sugar Control by Reducing Insulin Resistance

2. Promotes Better Health by Fighting Inflammation

3. Enhance Heart Health by Improving Blood Pressure, Triglycerides and Cholesterol Levels

4. Boost Brain Function and Prevent Neurodegenerative Disorders

5. Aids Weight Loss by Limiting Calorie Intake and Boosting Metabolism

6. Increases Growth Hormone 

7. Delay Aging and Extend Longevity

8. Aid in Cancer Prevention and Increase the Effectiveness of Chemotherapy

Fasting is not recommended for everyone! Consult your doctor and proceed at your own risk. 

Side effects of fasting include dizziness, headaches, low blood sugar, muscle aches, weakness, dehydration and fatigue. Prolonged fasting can lead to anemia, a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. The risks get more complicated and severe the longer you stay on a fast, or if you repeatedly go on fasts.

Individuals who are underweight, struggling with weight gain, under 18 years of age, pregnant or breastfeeding should avoid prolonged fasting. People with comorbidities like diabetes and heart disease should consult a professional before attempting prolonged fasting.

Geeked-out research:

“72 hours of food restriction can induce widespread upregulation of autophagy in CNS neurons. Disruption of autophagy can cause neurodegenerative disease, and the converse also may hold true: upregulation of autophagy may have a neuroprotective effect. Starvation in neuronal cell lines can remove toxic molecules and damaged mitochondria from neurons.”  

Cheng, Adams, Perin, et al. Prolonged Fasting reduces IGF-1/PKA to promote hematopoietic stem cell-based regeneration and reverse immunosuppression

“Our results indicate that cycles of an extreme dietary intervention represent a powerful mean to modulate key regulators of cellular protection and tissue regeneration but also provide a potential therapy to reverse or alleviate the immunosuppression or immunosenescence caused by chemotherapy treatment and aging, respectively, and possibly by a variety of diseases affecting the hematopoietic system and other systems and organs. Prolonged fasting reduces damage in bone marrow stem cells.”

Cheng, Adams, Perin, et al. Prolonged Fasting reduces IGF-1/PKA to promote hematopoietic stem cell-based regeneration and reverse immunosuppression

“It is now understood that fasting can switch the metabolism from using glucose as fuel to using fatty acids. This shift seems to trigger our stem cells to become more active and regenerative. Prolonged fasting can activate pathways that enhance immune system regulation improving cellular resistance to toxins and stress. Stem cells drastically increased their rate of regeneration in subjects who were in a fasted state.”
