The Fattening of America
Insulin injections are one way to treat diabetes.
You Going To Store That?
The ability to rapidly put on weight in the form of storage fat is a great advantage for animals in changing environments. This allows animals to eat large when resources are plentiful, storing the excess energy they gain as fat and then living off this fat when resources are scarce. It's a nice little system which helps animals survive. This situation applies to humans as well, except in many countries, especially the United States, humans are very good at producing, eating and storing food so those lean times the fat is being stored for are few and far between. What does this situation mean? Problems! For some people, life-threatening problems. Our bodies developed to deal with conditions of "feast and famine" not "feast and feast". Simply put, this situation is starting to affect people's health.
