Food is no longer used as fuel for our bodies, but has become a means to please our taste buds and overfill our stomachs. We should eat only to fuel our bodies for daily activities. There is only so much food our bodies can burn for energy immediately, and the excess is stored as fat in case of a famine. Our bodies are not gaining fat out of spite or to get back at us for something. Fat supplies are a natural and necessary part of human functioning.Without fat our bodies would not be able to stay warm in cold conditions, and it also insulates our bones, muscles, and organs. It is also a way of preventing starvation. When we overeat and the excess calories are not burned off through exercise, they are stored in the fat cells for later use. Since we are eating more and more in our current culture, the fat cells have no choice but to grow larger and larger.
