Long-term fasting, also known as extended fasting, is a practice that involves abstaining from food for extended periods of time.  This is typically for more than 24 hours. When done safely, long-term fasting can have numerous health benefits.  However, it’s important to prepare properly for a long-term fast and to understand the risks and benefits before starting.

Some Long Term Fasting Benefits

  • One of the most well-known benefits of long-term fasting is weight loss. When the body is in a fasted state, it begins to burn stored fat for energy instead of relying on the glucose from recently consumed food. This can lead to a reduction in body fat and an improvement in overall body composition.(1) Additionally, long-term fasting can improve insulin sensitivity, which can help regulate blood sugar levels and reduce the risk of diabetes.(2)
  • Another benefit of long-term fasting is the reduction of inflammation in the body. Inflammation is a natural response to injury or infection, but chronic inflammation can contribute to the development of diseases such as cancer and heart disease. Long-term fasting has been shown to reduce inflammation by promoting the production of anti-inflammatory molecules called cytokines.(3)
  • Long-term fasting can also have positive effects on brain function.(4) Studies have shown that fasting can promote the growth of new nerve cells in the brain, as well as improve cognitive function and memory. Additionally, long-term fasting has a strong link in the production of a protein called brain-derived neurotrophic factor (BDNF).  This is thought to play a role in the growth and survival of nerve cells.

How to Prepare for a Long Term Fast

Before starting a long-term fast, it’s important to prepare properly. This includes making sure you are in good health and consulting with a doctor or dietitian. It’s also important to start with shorter fasts and gradually increase the duration as your body adjusts. Additionally, it’s essential to stay hydrated and supplement with electrolytes during the fast to prevent dehydration and electrolyte imbalances.

Some Things You Need to Understand About Fasting

  1. First, understand that long-term fasting is not appropriate for everyone.  Certain individuals, such as pregnant or breastfeeding women, children, and people with certain medical conditions, should not participate in long-term fasting without the approval of a healthcare professional.
  2. Overall, the long-term benefits of fasting, like weight loss, improved insulin sensitivity, and reduced inflammation, are just some of the advantages that one can get by practicing long-term fasting. However, it’s essential to prepare properly and understand the risks before starting a long-term fast.
  3. It’s also important to note that long-term fasting is not a replacement for a healthy diet and regular exercise. While fasting does have many benefits, it is a tool folks use in conjunction with other healthy lifestyle practices.
  4. Another important aspect to consider when preparing for a long-term fast is to make sure you have a plan in place for breaking the fast. Going from a long period of no food to suddenly eating a large amount can be hard on the body and can lead to digestive issues. You should start with small, easy-to-digest meals and gradually increase the portion size and complexity of the meals as the body adjusts.
  5. Additionally, it’s important to understand that fasting for extended periods of time can have an emotional component. Fasting can trigger feelings of hunger and irritability, and it’s important to have a support system in place and to be prepared for these emotional challenges.

The Bottom Line Regarding Long-Term Fasting

Long-term fasting can have many health benefits when done safely and properly. However, it’s essential to prepare, understand the risks, and to not use fasting as a replacement for a healthy diet and regular exercise. It’s also important to have a plan in place for breaking the fast. Be prepared for the emotional challenges that may arise. As always, it’s recommended to consult with a healthcare professional before starting any new dietary or exercise regimen.

It is important to mention that the health benefits of long-term fasting, such as weight loss and reduced inflammation, are not only physical but also mental and emotional. For example, long-term fasting has shown to improve focus, concentration, and overall well-being. Furthermore, some research has shown that long-term fasting may even have anti-aging effects, slowing down the aging process and promoting longevity.

It is also worth mentioning that different types of long-term fasting protocols exist, such as intermittent fasting, alternate-day fasting, and extended fasting. Each of these protocols has its own set of rules and guidelines, and it is important to choose the one that best suits your lifestyle and goals.

In summary, long-term fasting, when done safely and properly, can offer a wide range of health benefits. It is important to prepare, understand the risks, and consult with a healthcare professional before starting any long-term fasting protocol. Additionally, it is important to not use fasting as a replacement for a healthy diet and regular exercise, and to have a plan in place for breaking the fast. The long-term benefits of fasting can be significant, and it is worth considering incorporating this practice into your lifestyle.
