Although there are theories that our bodies are designed and wired in such a way that you can go long periods of time without eating, and that our bodies may actually benefit from fasting periods, recent research shows that fasting is in fact anything but healthy.
Food = Energy = Health
Much like car doesn’t go without fuel, your body won’t last long without food. When we eat regularly, our digestive systems turn carbohydrates into the sugar glucose, which is our major source of energy.
Glucose is then extracted from the digestive tract and pumped into the blood stream, making sure all the cells in your body are provided with this precious fuel.
But what happens when you stop eating? If you deprive your body from food, the glucose supply in your bloodstream drops significantly, triggering your body to drain the energy from the stored glucose called glycogen.
The tricky part begins when the glycogen is all used up, then your body starts to burn fat in order to make its own glucose. This is When the Ketosis mode kicks in.
Ketosis mode basically means that you now burn fat as the primary source of fuel. Now, you are probably thinking – Hey, that’s great! I’ll even lose some weight along the way. But the reality is not that peachy, actually.
Many nutritionists and experts say this phase is bad for your heath because it makes your blood become more acidic, which can cause fatigue and even lead to kidney and liver damage.
