• Induces cellular repair throughout the entire body
• Promotes brain health by reducing oxidative stress and brain inflammation
• Prevents neurodegenerative diseases such as Alzheimer’s, Parkinson’s and Huntington’s diseases

Dr. Hsu gives us the backstory and knowledge we need to better understand the sacred mechanism of fasting. 

Did you know that around 5-6am is when all the stress hormones surges? This is when the adrenal glands really begin to kick in.

When reasonably applying fasting, there is major rejuvenation going on within the body. 

As Dr. Hsu says: “If we were to reduce or take away the source of calories for a period of time, the body is in this crisis moment, so it taps inside and goes to the fats– the central fats– it asks itself: ‘what can I get rid of?’ And when that fasting period passes, when the nutrients come, now the body can form new parts to rejuvenate new cells.”

Fast. Re-eat. Fast. Re-eat. These are the cycles of fasting and the cells way of remaining youthful…longer! I think we all want that ;)

Fun fact: Fasting affects every cell in the body– including brain cells! 

After 5 days of prolonged fasting, people experience 4 levels of changes…

1. Midsection weight loss (this fat is a source).
2. Your body finds fasting as stress. So this is a stress that sharpens your mind & preserves your muscles. 
3. You feel better! Clarity of the mind. Focused.
4. You feel a sense of achievement.
5. Your cells are rejuvenated
