The 6 Stages of Fasting: A fascinating journey for Body and Mind.
Stage 1: The Fed State – Understanding the effects of a regular diet on our body.
Stage 2: The Post-absorptive State – Transitioning from a fed to a fasting state.
Stage 3: The Early Fasting State – Unveiling the metabolic changes during the initial hours of fasting.
Stage 4: Fat Adaptation – The body’s transition to utilizing stored fat for energy.
Stage 5: Gluconeogenesis – Discovering how the body creates glucose during prolonged fasting.
Stage 6: Autophagy – Unleashing the body’s self-cleansing mechanism in prolonged fasting.
Welcome, dear reader, to a captivating exploration of the 6 Stages of Fasting. Within these stages lies a fascinating journey that influences our body’s metabolic processes and affects our mental well-being. So, fasten your seatbelts as we embark on this enlightening adventure!
In the first stage, aptly named the Fed State, we face the effects of a regular diet on our bodies. Most of us spend our lives in this state, where the body uses carbohydrates as its primary fuel source. During this stage, insulin levels spike, signaling our cells to absorb and store excess glucose. However, as we delve deeper into the stages of fasting, we begin to witness a shift in this metabolic paradigm.
Transitioning from the Fed State, we enter the Post-absorptive State, our second stage. Here, the body starts to move away from relying on the readily available glucose and shifts toward utilizing stored energy. As insulin levels drop, the body begins tapping into glycogen reserves, breaking them down into glucose to meet immediate energy needs. This transition paves the way for our journey into the fasting state.
Stage three, known as the Early Fasting State, takes us into the initial hours of fasting. It is during this period that our body begins to undergo significant metabolic changes. The body’s glycogen stores are almost depleted, driving the liver to ramp up the production of ketone bodies. These ketones are an alternative fuel source, providing energy to our brain and other vital organs. Additionally, the release of growth hormones and increased adrenaline levels facilitate fat mobilization, engaging our body’s ability to burn stored fat for fuel.
Our fourth stage, Fat Adaptation, marks a pivotal moment in the fasting journey. As the body becomes increasingly efficient at using fat as its primary energy source, we reap the benefits of fat adaptation. Ketone bodies, produced as a byproduct of fat metabolism, become the preferred fuel for our brain, replacing glucose. This transition not only aids in weight loss but also enhances mental clarity and provides a stable, sustainable energy source.
Moving forward, we encounter Stage Five: Gluconeogenesis. This intriguing process showcases the body’s ingenuity in creating glucose without dietary carbohydrates. Gluconeogenesis primarily occurs in the liver, which converts non-carbohydrate substrates, such as amino acids, lactate, and glycerol, into glucose. This ensures a steady supply of glucose to meet the demands of our red blood cells, specific brain cells, and other glucose-reliant tissues.
Finally, we reach the sixth stage of our fasting journey: Autophagy. This stage holds immense promise for unlocking the body’s self-cleansing mechanisms. In prolonged fasting, when glycogen stores are further depleted, our body enters a state of autophagy. Old and malfunctioning proteins within our cells are broken down and recycled during this process. Autophagy helps maintain cellular health and plays a vital role in reducing inflammation, protecting against aging-related diseases, and potentially even mitigating the risk of certain cancers.
As we conclude this whirlwind tour through the 6 Stages of Fasting, we gain a deeper appreciation for the intricate interplay between our diet, metabolic processes, and overall health. By understanding these stages, we can harness the power of fasting to optimize our metabolic flexibility, improve insulin sensitivity, and promote overall well-being.
Remember, dear reader, that fasting is not suitable for everyone, and it is always essential to consult with a healthcare professional before embarking on any fasting regimen. However, for those who can safely incorporate fasting into their lifestyle, the potential benefits are vast and awe-inspiring. So, whether you consider intermittent fasting or more extended fasting periods, may your journey through the stages of fasting be enlightening and transformative!

Today I want to cover the six stages of fasting.
The six stages of fasting:
Stage 1: 8-14 hours
• Stable blood sugar levels
• Using up stored sugar and sugar in the blood
• At 10 hours—the muscles use about 50% glucose and 50% fat (you’re starting to transition to fat-burning)
Stage 2: 14-24 hours
• Starting to get into ketosis
• Fewer cravings
• More energy
• Improved mood
• Improved cognitive function
Stage 3: 24-36 hours
• Full ketosis and fat burning
• The liver is making ketones
• Decreased appetite
• Decreased ghrelin
• Increased BDNF (new brain cells)
Stage 4: 36-48 hours
• Autophagy
• Kill cancer cells
• Decreased oxidative stress
• Decreased misfolded proteins
• Increased memory
Stage 5: 48-60 hours
• Insulin sensitivity super boost
• More autophagy
• Less inflammation
• Atrophy healing
• Protein sparing
Stage 6: 60-72 hours
• Immune system regeneration
• Spike in immune stem cells
• A 2014 study demonstrated that a 72-hour fast led to a complete rejuvenation of the immune system, and people on chemotherapy had less damage
