Stage 1 Fasting (8-12 Hours): Stable Blood Sugar

Fasting begins about eight hours after your last meal, and during this stage, your blood sugar levels undergo changes. Initially, you may experience symptoms like hunger, fatigue, food cravings, and difficulty concentrating. However, if you push through this initial phase, these symptoms will quickly subside. At around the 12-hour mark, your body starts tapping into glycogen stores and stabilizes blood glucose levels. Additionally, you begin transitioning into the early stages of ketosis, where your body burns fat stores for energy instead of relying on carbohydrates.


Stage 2 Fasting (12-18 Hours): Ketosis, Fat Burning, and Mental Clarity

After fasting for 16 to 18 hours, your body should be in full ketosis. This stage offers several benefits, including appetite suppression, making fasting easier as time goes on. It becomes an ideal phase for weight loss, as your body efficiently burns fat and reduces the hormone ghrelin, which triggers food cravings. Moreover, you'll experience mental clarity and improved mood as brain-derived neurotrophic factor (BDNF) increases, supporting brain health.


Stage 3 Fasting (24 Hours): Autophagy and Anti-Aging

Once you reach the 24-hour fasting mark, your body enters repair mode, initiating autophagy—a process where cells recycle damaged components and improve efficiency. Autophagy has been associated with various benefits, such as clearing out harmful proteins linked to Alzheimer's disease, combating age-related decline, and potentially aiding in the elimination of cancer cells. Additionally, fasting during this stage reduces bodywide inflammation, contributing to overall well-being.


Stage 4 Fasting (36-48 Hours): Growth Hormone and Recovery

As you progress into longer fasting periods, around 36 to 48 hours, your growth hormone levels start to shift. This leads to increased muscle growth and faster muscle repair, making fasting surprisingly beneficial for maintaining and building muscle mass.


Stage 5 Fasting (72+ Hours): Stem Cells and Immune Function

The final fasting stage occurs after a full three days without food. A 72-hour fast triggers the production of stem cells, revitalizing the immune system. Studies have shown that fasting during chemotherapy can help protect the immune system in cancer patients.
