- 46 - A Man Without Physical Exercise is a Permanent Danger to The National Food Supply Did you know that a person who takes regular exercise and his health and energy is in good condition, can preserve most his energy from his diet and can use it when time requires? Scientic experiments have proved that a healthy exercising person is capable of using 55% of his energy while a person with the same build and age but who takes no exercise uses only 17-27% of his power while the rest is wasted. In other words, a person who takes no exercise is a permanent danger to the national food supply. If he consumes 100kg of wheat, he uses only 16-27kg of energy and the rest is wasted. In contrast, a healthy person who takes exercise uses 55kg of his energy and only 45% is wasted. Is it Possible for a Man to Convert 100% of What He Eats Into Energy? No, it is not possible. The human being is a machine like any other. As other machines cannot convert 100% of their fuel into energy, similarly it is not possible for a human being. A part of his food goes to waste. Take the example of an electric engine, considered to be very efcient, it uses only 80% of energy input and 20% is wasted. A steam turbine has only 40% efciency level while the car engine is efcient up to only 30%. Steam engines use only 10-15% of the consumed energy and the rest is wasted. Coal-red steam engines use 10-15 tons of coal energy from every 100 tons consumption of coal and 85-90 tons of coal is wasted. If we make a comparison of these efciency gures, we realise that a healthy, exercising person who can utilise 55% of his energy is only second to the electric machine and has superiority over other devices.
