There are basically 2 sources of energy that the body utilises. Under normal circumstances your body will burn fat. In fact that is what the body prefers to do – burn fat. Fat takes a longer time to covert into usable energy for the body. It provides prolonged, sustainable and clean energy, coming from the liver and the fat cells in our body. It’s also less stressful for the body.
If you are exercising somewhat hard, where you can speak 5 words – My name is Vasu Dev – before having you gasp for air again, then you’re probably exercising at an aerobic rate. Your heart is beating between 60% and 70% of your maximum heart rate and your body is using oxygen to burn fat for energy.
Under stressful circumstances however, the body requires instant energy. For example, when you are being pursued by a lion. You need instant energy to get away from the threat. The body will shut down the fat burning process and use the glycogen (stored sugar) in your muscles. It shifts to what’s called an anaerobic rate. Your heart is beating between 80% and 100% of your maximum heart rate and does not use oxygen.
In this state, the body shuts down the fat burning process. It converts glycogen into energy and produces, as a by-product, lactic acid, which creates the painful ‘burn’ in muscles. So when you’re running real hard, and are panting like mad, YOU ARE NOT BURNING FAT and NOT USING OXYGEN! You are stressing your body and producing lots painful lactic acid and a lot more free radicals in the process. Result – no immediate fat loss and free radical damage.
