Benefits of prolonged fasting


A prolonged fasting has amazing benefits and everyone should be trying a 2-3 day fast once in a while. This might sound like an impossible mission to many but your body will thank you after it. Let’s see why!

Free your mind

Intermittent fasting for 16-20 hours is great daily practise, but going deeper into a fasted state will greatly enhance some of the benefits.

But before talking about the science of fasting, let’s talk about the first and main benefit of a prolonged fast. It is freedom of mind. Staying away from anything for a period of time can be liberating. Habits can be addictive since they are low-key activities we do day-in day-out. And our mind likes things staying the same. Take food for example. We mostly eat at the same times every day and our mind reminds us of the fact every single time. You need to eat! This can apply so many other things as well. A coffee fast would also be a good idea and that is why we have it as a challenge in one of our series

Fasting Benefits

If you choose to start fasting, you will have great benefits, so keep an open mind and don’t worry even if you have to stop early.

  • Growth Hormone secretion can increase by up-to 400% for a 2-day fast, . GH is important for growth, cell regeneration, repairing healthy tissue in the brain and other organs. It speeds up healing, muscle tissue repair and protcts the joints.
  • Autophagy is the process of removing accumulated toxins and recycling old cells. The process is triggered in an energy deprived state (with the absence of insulin, mTOR )
  • Inflammation (both acute and chronic) will reduce by giving a chance to your body to focus on healing. Eating and digesting takes up-to 60% of the bodys energy leaving little time for any other process to kick-in and be be effective.
  • Stem cells provide new cells for the body to replace old or damaged ones. As we age stem cells reduce and/or become less potent. A lot of research and investment is going into this field recently, but fasting is a natural way to enhance our stem cells.
  • Mitochondria are increased. Mitochondria are the power plants in our cells responsible for the energy we have. Fasting gets rid of the old mitochondria and at the same time stimulates new growth. This process of renewing your mitochondria may play a huge role in the prevention of many of the diseases we currently have no acceptable treatment — diseases of excess growth.
  • Brain cells growth especially in the hippocampus involved with memory cells.
  • Andioxidants increase.
  • Cell resistance increase to stress.


  • Fasting benefits change depending on the duration. With a prolonged fasting you trigger autophagy and create new stem cells.

  • Drink black coffee and green tea.
  • Drink water with some salt and lemon to get some electrolytes and sodium.
  • During the fasting your body will start releasing toxins. To support the detoxification process take activated charcoal.

How to break a fast

After a couple of days of fasting your gut has adapted to the abstinence of food, by preserving digestive processes. So you need to be careful to not put too much stress on your body which will cause excess inflammation. Refeed slowly. Additionally consuming high amounts of carbohydrates may result in an abrupt weight gain due to sodium retention. While fasting you excrete a lot of water and refeeding on carbs will get you bloated and you may also have an energy crash of insulin.

  • Drink first some water with ACV to trigger your bodies digestive enzymes.
  • Then break your fast with some bone broth. Bone broth is amazing because it has a ton of electrolytes but it’s also packed with collagen. Bone broth will also help you to absorb the other electrolytes and minerals a lot better. Your gut has been cleaning house for a while and is now ready to utilize the nutrients you’ll be consuming afterward.
  • After 30 minutes have a relatively small meal and low glycemic, no matter what diet you’re on. This will keep you in a semi-fasted state because of the non-existent rise in blood sugar. Aim for around 500 calories. Eggs are a great option since they are easy to digest and carry a lot nutrients.

When to stop early

Although a three day fast is not considered a long fast, there are some occasions that you might need to consider breaking your fast early. Always listen to your body and the signs it sends.

  • If you painful hunger which does not go away. Try some MCT Oil if this happens.
  • If you have strong dizzyness and you can’t stand-up or keep your balance. Some light headiness is normal and goes away by adding salt to your water.
  • If you have insomnia and can’t sleep. Your sleep might be affected during your fast but we still need respect the quality of our sleep.
