Evolution has engineered all animals to seek nutrition to sustain themselves. Because sources of nutrition may become available only very intermittently, many animals will try to eat as much as possible when there is food in order to sustain themselves until the next time that food is once again available. We human beings are only too aware that in many places, plentiful, high calorie food sources are available whenever they are wanted. This can often lead to overeating with the result of becoming overweight. As we have learned, obesity is the root cause of a wide variety of health problems, including diabetes, heart disease, and decreased mobility, among others.
