Why Fast?

Are you wondering what will happen to your body when you fast? Cuz if you are you should know that fasting will provide benefits that extend far further than just burning fat and making your diet more sustainable and enjoyable.

When your body goes without food for a certain period of time, you’ll experience changes that effect your brain, your digestive system, immune system, hormones, and even the function of all the microscopic cells found within your body.

When you first begin fasting a few things happen at the cellular level that may cause hunger and fatigue if you’re a beginner. This is because your body will normally get it’s energy from glucose or carbohydrates, so depending on how much sugar you have in your blood, and how much glycogen or carbohydrates you have stored in your muscles and your liver, it can take anywhere from 8 to 48 hours without food for your body to switch from mostly using glucose or carbs (sugar) for energy to breaking down fat and using ketone bodies for energy in a process known as gluconeogenesis.


Hunter Gatherers & Evolution

Now, to most people, the concept of going anywhere from 16 hours up to a few days without food may sound incredibly foolish and unhealthy but the exact opposite is actually true and it hasn’t always been so mainstream to eat at least 3 times a day everyday. Human beings have evolved to be perfectly capable of going long periods without food. And this is supported by research on modern hunters and gatherers that shows that they go between intermittent periods of feeding and fasting depending on the availability of food.

For example modern Bushmen living in Africa go through frequent periods of food deprivation ranging from 1 to 10 days when they can’t catch any game, or when they have seasonal droughts, or especially when animals migrate. The truth is that most healthy adults have evolved to be perfectly capable of fasting and the good news is that you don’t have to fast for 10 days to experience the benefits for your body. Just 16 hours will provide some really unique beneficial effects.



And when going through your first 16 hours without food the first thing you should expect is to start feeling really hungry right around your regular meal times that you’re skipping. This is because of a hunger hormone in your body known as Ghrelin, which stimulates your appetite when it’s released. And studies show that ghrelin levels will spike up at the times of the day that you normally eat, which for most people is breakfast, lunch, and dinner.

This will happen to your body automatically, and if you give in and eat before your fast is over the same thing will happen again the next day. On the other hand if you just ride out that hungry feeling, within about 2 hours after the initial spike in ghrelin, it should drop back down to normal levels and your appetite should drop.

And as your body adapts more and more to skipping a meal like breakfast or multiple meals throughout the day you’ll feel less of those automatic cravings to eat during those key times of the day that you normally find yourself hungry. If you allow yourself to adapt to consistently fasting for just 16 hours a day, while eating a healthy diet during the other 8 hours your body will start to become much more sensitive to insulin.



Having higher insulin sensitivity will not only help enhance fat loss, it’ll also help you feel much better when your body doesn’t have carbs available for energy, and it’ll help reverse or reduce the risk of a number of serious diseases like diabetes, high blood pressure, heart disease, and even thyroid conditions. Now, during each of your 16 hour fasts, about 6 hours into the fast your body will begin going through another incredible process known as autophaghy.



This is a process where your body begins destroying old or damaged parts of your cells. When you’re always eating your body doesn’t get a chance to do this because it’s constantly rebuilding rather than breaking down. And breaking down unnecessary and dysfunctional components of your cells allows them to be recycled so they can perform optimally.

This helps reduce inflammation throughout the body which helps fight a number of diseases. The benefits of Autophaghy will also extend to your skin cells potentially slowing down wrinkles, age spots, and acne. Your immune system will also improve thanks to autophaghy. Your body will repair and produce brand new white blood cells…
