Extreme intermittent fasting is gaining popularity, but what are the real biological changes and potential risks involved?
At a Glance
- Intermittent fasting typically involves an eight-hour eating window and is popular among celebrities.
- Prolonged fasting offers health benefits but requires medical supervision if extended beyond 72 hours.
- Autophagy and ketosis are triggered around the 36-hour fasting mark, aiding longevity.
- Prolonged fasting may not be suitable for those with certain health conditions.
- Gradual fasting duration and post-fast nutrition are crucial for safety and effectiveness.
Biological Shifts in Extreme Fasting
Extreme intermittent fasting goes beyond the traditional model of fasting for 16 hours and consuming meals within an eight-hour window. Dr. Chris Rhodes emphasizes the intricate biological changes that manifest, especially when fasting exceeds 24 hours. One of the key processes is autophagy, a cellular cleanup mechanism that is upregulated during prolonged fasting, potentially reducing the risk of chronic diseases and aging. As fasting continues, the body enters ketosis, burning fat for energy – nypost.com
Despite these benefits, extreme fasting without medical oversight can be perilous, leading to possible complications like micronutrient deficiencies and reduced metabolic rates. Health benefits generally appear around 36 hours of fasting, but exceeding 72 hours without supervision might trigger starvation mode, depleting the body’s essential reserves.

Challenges and Considerations
Extreme fasting requires caution, particularly for those with underlying health issues such as diabetes, hypertension, or hormonal imbalances. Pregnant women, nursing mothers, and individuals with eating disorders should avoid these fasting practices due to potential risks. Psychological factors and negative impacts on growth and development must also be considered. Incorporating adequate nutrition post-fast is vital to maintain bodily functions and promote recovery.
Dry fasting, which involves abstaining from both food and water, has sparked interest due to its potential health benefits. Here's an overview:

Fasting With a Plan
Gradual adaptation is crucial for those new to fasting, often beginning by skipping breakfast and gradually extending fasting periods. Prolonged fasting can also challenge traditional perceptions of constant eating, suggesting a shift in how society views food dependency. Supplements, along with strategies such as hydration through tea and water, can help manage hunger pangs during fasting periods.
As alternate-day fasting has shown benefits like weight loss and enhanced metabolic parameters, these planned fasting routines warrant further exploration. Fasting can alter energy metabolism, thereby potentially contributing to improved immunity and brain health, along with lowering the risk of Type 2 diabetes and other chronic illnesses.
