To better understand the exact processes behind Flash Keto, we will first see what happens when you eat. Consume food for one reason and for one reason only – to provide your body with the energy it needs to function. It’s the fuel of your engine. Foods are digested and converted into energy that can be measured in calories. Calories are burned for energy during activity and metabolism. Now, when the body has no food or calories to burn energy, it turns into stored fat for energy use. That’s why, if you do not have the new fuel, the body turns into stored fuel, that’s how the system works.
