Don't Ask the Monkeys

Researchers at the Oregon National Primate Center conducting studies of fat monkeys have determined that obesity among primates is deleterious to their health. A group of monkeys was fed a steady diet of fatty and sugar laden food in order to make them obese. Some of the monkeys were kept locked in their cages to simulate the lack of physical activity that often accompanies over eating. "We were trying to induce the couch potato style" said one researcher. As expected, the monkeys gained weight. Some became obese. Monkeys were used because, in addition to their similarity to humans, their diet and activity are easily controlled and monitored. More importantly, they do not lie about what they eat.

Several conclusions were made from the study. First, eating poorly and physical inactivity leads to weight increase. Secondly, monkeys, like people, prefer rich, fatty foods and tend to eat when they are bored. Lastly, it was observed that obesity in monkeys leads to health problems such as diabetes.

Arguably, there are few reasons to study obesity. We know what causes it and we know what results from it. The only thing we are not sure of is why people seem complacent about it. Most people who are overweight know they are overweight. With few exceptions, they also know why they are overweight and that being so is not good for their health.

There is really nothing mysterious about the phenomenon of obesity. People are prone to doing things they should not do. They lie when they know that lying is wrong. They watch TV when they know they should be working in the yard. They spend time on facebook when they know they should be doing something else. They eat potato chips by the bag full when they know no good will come from it. The phenomenon of doing something we know is harmful or that we should not do is a subject that has perplexed thinkers for thousands of years. The only thing that has changed is the perception of the problem.

Human behavior has shifted from being a philosophical and theological problem to a psychological and physiological one. I doubt scientists will have better luck in getting to the bottom of why people conduct themselves as they do than St. Augustine and Aristotle did. If anything, they will accomplish less. Aristotle and St. Augustine sought to understand human behavior. Scientists only try to explain it.

Scientists are searching for a cause or trigger: a gene, a brain chemical, an environmental factor, something to explain obesity. They will not find one. What they should be looking for is character and self discipline. Every one should be looking for those. In the mean time, we will keep spending time and money trying to understand what any good high school football coach already knows: if you want to lose weight and get in shape put down the cup cakes and start moving.

It is unclear to me why the study was conducted. If the purpose of the study was to learn the consequences of poor diet and inactivity, it was a waste of time. We know what those consequences are. If the study was aimed at learning the cause of obesity, it was an equal waste of time. We know what causes obesity and, as importantly, we know how to get rid of it. The only thing we are unsure of is why some people don't seem willing to do anything about it. We will not get the answer to that from studying monkeys. Monkeys don't know any better, people do.
