Protein, Energy Production and Heat Generation
The biological need for food is simple – we need to eat so that we have energy. Even if the goal is only to sit on the couch and watch a hockey game, we still need energy to exist. The human body is an amazing machine, but it needs fuel even when it is doing nothing at all, even when it is sleeping. Every function of the human body requires energy, from the beating of our hearts to the expanding of our lungs. Our body also uses energy to grow our skin, hair and nails. If we do not have the right kind of energy in our system, then these functions will cease, not only affecting the way that we look, but also how we feel. If the deficiency continues for long enough, our health will suffer as well.
