While reading the section readings for this week, I was very confused. The readings included two articles: “7 Myths About Physical Activity”and “Hunter- Gatherer Energetics and Human Obesity”. “7 Myths About Physical Activity” talked about how beneficial exercise is no matter one’s age and how people these days are not getting enough of it. However, “Hunter-Gatherer Energetics and Human Obesity” talked about how a recent study showed that the total daily energy expenditure (TEE) among Hazda hunter-gatherers was not that much different than that of Western populations. One would think that because Hazda hunter-gatherers have to walk, gather food, hunt, etc. they would get more physical activity, but the study showed that this was not the case. I nodded my head while reading the first article, thinking “yeah this is so true, I should start working out more often”, but while reading the second article, my face was always in a “huh?” expression. It just didn’t make sense to me. The study showed that the “Hazda were highly active and lean, with body fat percentages on the low end of the normal healthy range for Western populations” (Pontzer), but they had the same TEE as Westerners, who are known to be overweight and obese. I tried to think of reasons why this might be or maybe even something that the scientists had missed. The only reason I could think of was this. The reason why Westerners are obsess and the Hazda are not, even though they have the same TEE, is because of the amount of energy intake. Westerners are probably eating so many more calories than the Hazda that even though they have the same amount of physical activity, they are not burning it off. While the Hazda’s physical activity is enough to keep them fit and lean, because of the amount of calorie intake of Westerners, their physical activity is not enough to keep them fit. Not only is the calorie intake the problem causing obesity, but it is also true that the Western diet is probably more consisted of fattier, unhealthy foods. I came to the conclusion that while physical activity and exercise is very important and beneficial to our bodies, our diet is equally as important. If one vigorously exercises but eats a lot of junk food, there is no point.
