The feeling of ‘hunger’ drives us to eat. Our brains require energy, which is derived from the foods and fluids we consume. Without enough energy, our brains cannot run effectively, and our bodies begin to shut down.
Appetite is based on pleasure, and is influenced by what we see, smell, taste and even think! You may be familiar with the concept ‘Pavlov’s dog’ which describes a process of conditioning dogs to salivate when exposed to the idea of food. This same concept applies to humans, as when we’re tempted with something tasty, our bodies react and prepare by increasing saliva and excitement levels.
