Intermittent fasting is popular these days. And for a good reason. When the body goes without food for a while, what we call fasting, two important things happen.
First, the body experiences mild stress and tries to increase efficiency and prepare for tough times. This mild stress brings about increased repair, increased elimination of toxins and recycling of nutrients. Consequently, your body functions better. Of course, fasting for too long has negative impacts.
Second, the body often runs out of glucose, its primary source of fuel, and begins to rely on ketones, a source of fuel that comes from fats stored in the body. Therefore, the body begins to breakdown fat as a source of energy. Breaking down fat can lead to weight loss which is why many people would like to have ketones as their primary source of fuel.
