WHAT IS FASTING?
Fasting is the voluntary abstention from food, and sometimes drink, for a set period. It is not starvation, but a deliberate pause that allows the body to rest, repair, and reset. It’s one of nature’s most ancient healing mechanisms.
---
WHY IS FASTING SO COMMON IN NATURE?
In the Wild: Animals instinctively stop eating when sick, injured, or stressed.
During Winters: Bears hibernate for months without eating.
Migration: Birds, whales, and butterflies fast while covering thousands of miles.
After Birth: Newborns often don’t feed for several hours as the body adapts.
Instinctive Reset: Fasting happens naturally when food is scarce or unneeded.
Fasting is hardwired into survival and healing — across species, across ecosystems.

HOW FASTING WORKS IN THE BODY
1. Switches Fuel: Body shifts from glucose to stored fat (ketosis).
2. Cleans Up Waste: Triggers autophagy — cellular self-cleaning.
3. Reduces Inflammation: Pro-inflammatory markers decline.
4. Boosts Stem Cells: Regenerates immune cells and tissues.
5. Balances Hormones: Improves insulin sensitivity, growth hormone spikes.
6. Sharpens Brain: BDNF (Brain-Derived Neurotrophic Factor) increases.
7. Reverses Damage: Promotes healing in liver, heart, gut, and brain.

WHY FASTING IS NATURE’S FIRST AND LAST CURE
First Cure: When an animal is ill, it stops eating. Digestion demands energy — fasting redirects it to healing.
Last Cure: Chronic, lifestyle-driven diseases often resist drugs — but yield to fasting (obesity, type 2 diabetes, hypertension, PCOS, fatty liver).
Beyond Physical: Fasting resets mental clarity, emotional stability, and even spiritual insight.
