Introduction: Hello my name is xxxxxxx xxxxxx and I am an Eating Disorder Counselor. Today I will be discussing the physiological reasons for eating or not eating and then I will open the floor for discussion.
There are two theories on why we get hungry; these theories are called the Set or Settling Point theory, and the other is the Positive – Incentive theory. The Set or Settling theory differs a bit in the point of optimal weight (or fat/energy level) however the basic idea is the same. In this theory everyone has a set point (or an equilibrium) where the body is using the stored energy, and if the body is above this point then it does not become hungry if it is below the set point the body is lacking energy to use and will become hungry in order to replenish the fuel supply. This theory is invalid for the simple fact if the body worked that way we would all be at our optimum weight.
The second theory is the Positive-Incentive whereas we desire to eat instead of eating because we need to refuel. We are programmed to eat for many reasons but we have a desire to eat to fulfill the basic needs of our bodies much like having sexual desire increases the chances that we will procreate.
How do we determine what to eat? Taste or what we have a preference to eating play a big factor in what we eat. If we eat what we prefer, salty, sweet, fatty, we are more likely to ingest food that is high-energy and contain vitamins and minerals to supply our bodies with nutrition. Another is learned tastes or preferences and aversions; most people eat what their families served or what the culture dictates. Also, many times we will eat food that is connected to good health versus toxic or something that is not good for us.
How do we know how much to eat? How much you eat depends greatly on the nutritive volume of the content. It may also depend on the last experience we had eating that certain food; if it was pleasurable we may tend to eat
