Insulin Converts Fat into Energy for Weight Loss
But the days in which you do not eat food by skipping meals, your body still needs to keep you alive by supplying blood to your brain and body by pumping your heart, continue your breathing etc all of which needs energy. This energy has to come from somewhere if your stomach and digestive system has no food in it for your body to get energy from. This is when insulin, the police man goes around and starts releasing the fat and converting the fat into energy which can be used for keeping your brain and body alive. But how much energy is required to keep you alive?
Approximately 1500 calories are required in a day just to keep your body alive even when when you are sleeping. So if you are eating food and not exercising at all, then ensure that you are eating food that gives you only 1500 calories. All the excess energy you eat will be converted into fat by insulin and stored as excess body fat reserve for converting back to energy when you do not eat food.
TWhen you exercise too much without eating trying to achieve weight loss, you feel very tired because there is no energy being provided from your digestive system as you did not eat any thing and also because insulin in your blood stream takes a long time to convert the stored fat into energy. So you need to eat a little bit to ensure you do not get tired and at the same time insulin converts some stored fat into energy and you achieve your goal of weight loss without starving.
