Fasting 101: 5 Reasons to Fast for Better Health

Discover how fasting extends lifespan, lowers insulin and blood sugar, reduces inflammation, regenerates gut cells, and promotes autophagy. Learn the science-backed benefits of fasting and how to implement strategic fasting protocols for metabolic health, cellular repair, and longevity. Nurse Doza breaks down when and how to use fasting as a powerful health tool. FEATURED PRODUCT Mitochondriac, featuring resveratrol with quercetin and methylated forms, is designed to support mitochondrial function and mimic the beneficial effects of fasting. Research shows resveratrol activates the same pathways as fasting—AMPK, SIRT1, and PGC-1α—promoting autophagy, mitochondrial biogenesis, and cellular repair. Pairing Mitochondriac with your fasting protocol enhances the metabolic benefits discussed in this episode, making fasting more sustainable and effective for longevity and energy production. 👉 Get Mitochondriac here: https://mswnutrition.com/products/mitochondriac JOIN THE SCHOOL Struggling to know how long to fast, what to eat before and after, or how to troubleshoot when a fast doesn't feel right? Inside the School of Doza, you'll join a community of people implementing fasting protocols just like you—and get direct guidance during our Wednesday "Ask Me Anything" sessions that function like group consults. Bring your questions about fasting duration, supplement timing, breaking your fast properly, or interpreting your labs while fasting. Get real-time answers and avoid common fasting mistakes.

Fasting lowers insulin and blood sugar – After approximately 10 hours of fasting, stored glycogen is consumed and the body begins breaking down fatty acids, lowering fasting insulin levels and improving insulin sensitivity. Fasting reduces inflammation – Fasting decreases inflammatory markers including TNF-α, TGF-α, and PDGF, addressing the root cause of conditions like fatty liver, diabetes, autoimmune disorders, and heart disease. Fasting regenerates gut cells – Caloric restriction increases the number of intestinal stem cells and enhances the regenerative capacity of the injured intestinal epithelium, healing gut damage at the cellular level. Fasting promotes autophagy and mitochondrial biogenesis – Fasting activates the body's cellular cleanup process (autophagy) and stimulates the creation of new, healthy mitochondria through activation of PGC-1α, AMPK, SIRT1, and NOS pathways.
