7 Levels of Fasting NOBODY Knows… Melt Fat, Repair Liver & Help Prevent Cancer

Summary

Ben Azadi presents fasting as a series of seven progressively longer fasts, arguing that each duration triggers different effects in the body. These are the presenter’s claims, not established guidance for everyone; the video also promotes fasting-related products and a book.

• Level 1 — 12 hours: Described as a beginner fast. Azadi says insulin falls and the body begins using stored glycogen. He also claims digestion has finished, potentially supporting focus and clarity.
• Level 2 — 16 hours: The presenter says this may increase autophagy, the process by which cells break down and recycle damaged components. He associates it with clearer skin, less puffiness, and sharper mornings.
• Level 3 — 24 hours: Presented as a way to support liver function and increase fat use and ketone production. The suggested practice is a 24-hour fast once a week. For hunger, Azadi suggests drinking water or distracting yourself while noting that hunger may pass.
• Level 4 — 36 hours: Described as an “immune system reset,” with claims about reduced inflammation and the recycling of older immune cells. The video mentions research involving autoimmune conditions while acknowledging that fasting is not a cure.
• Level 5 — 48 hours: The presenter claims fasting raises growth hormone and norepinephrine, which he says may help preserve muscle, increase fat burning, and support alertness.
• Level 6 — Five days: Azadi discusses research on prolonged fasting and fasting-mimicking diets, including possible effects on immune cells and cancer treatment. He suggests long fasts but says newcomers should seek medical guidance, especially if they take medication.
• Level 7 — Seven days: Framed mainly as a psychological challenge that may change a person’s relationship with food and sense of resilience. The video recounts a medically supervised 382-day fast as an extreme historical example, not as a recommendation.

Practical points and cautions

• The presenter encourages gradually building fasting experience and improving “metabolic flexibility” before attempting longer fasts.
• The video is not medical advice. Prolonged fasting can carry risks and should not be attempted without appropriate clinical guidance, particularly by people taking medication or with health conditions.
• The cancer-related discussion should not be taken to mean fasting prevents or treats cancer. The video references research on fasting alongside cancer treatment, not as a replacement for standard care.
• The video includes promotions for a berberine product, creatine, vitamin D, and Azadi’s book.
