Searcher: Energetics and Mammals

Week 7 
                                                                                                                                                                  In this week topic discussion, we have learned about far-reaching, detailed material about movement and energy expenditure/TEE.  In the readings, lectures, and class discussion we have studied physical activity vs. being sedentary, intake and output of energy, effects of a sedentary lifestyle on a biological level, weight gain and weight loss due to energy imbalances. We’ve studied energetics and psychology, and we also discussed positive and negative effects of high and low energy/activity levels (just to name a few). We have not discusses too much about congenital effects of a high-energy intake diet of a pregnant mammals. So what congenital effects occur when a pregnant animal eat a diet high in calories? What happens to the baby post birth?

I was not shocked about the findings to the question stated above. In the article I found,  there were chemical changes in the newborn monkeys brains due to the mothers high calorie fatty diet. These babies had higher anxiety levels, and metabolic problems.

The article is entitled “Today’s Lab Rats of Obesity: Furry Couch Potatoes”, and it relates to the class significantly. In this article from the New York Times, researchers are studying monkeys intake of energy as well as output. In this study, researchers are comparing human diseases, surgery outcome, weight loss outcome to monkeys, and shocking conclusions are drawn.
The outcome of the high-energy diet and the high-energy intake of humans is the same.
I was shocked to discover that high fructose corn syrup speeds up the rate of diabetes.
Some monkeys died from health related issues of an increased calorie diet, and some monkeys have developed chronic diseases like CKD, and DM. There was one monkey that ate health daily, but was naturally larger then the other monkeys.

In totality, size overall does not always determine if an individual is “healthy”. As we read in the article about the Hadza tribe, their lifestyle does not make them any healthier than those of westerns individual. But overall it is important to balance TEE, and out put of energy.

Random: I’m not sure if I’ve seen this video in this class, or another health class…but it’s really funny. Check it out…
