That's the old way of thinking. Scientist are beginning to think that genetics plays a larger role in obesity and they are looking for specific genes that control it. I understand the behavior angle, -if you don't put the calories in, the body cannot store it as fat. The body normally uses calories as energy and stores or excretes what it does not need. But in some cases much of what goes in gets stored instead of being used. And in the case of rail thin people, gets used instead of being stored. Once scientist unlock the key to this mystery, effective weight management drugs can be developed.
No, actually it isn't the "old way of thinking".
You see, the perspective that you're promoting above^^^^^^^^^^^^^^^^^^^^^^^^^^^
.......is assuming that the human body was made to be sedentary.
Sure, there is a certain "set point" that your body wants to gravitate to. But that set point is assuming that the individual is sedentary
. Again, scientist can try to come up with drugs to solve all of our problems, but that doesn't mean that they are necessary.....................and there will ALWAYS be side effects to any drugs used to treat anything.
Anytime you let anything set up without being used (i.e. a car, a bicycle, a house, a human body) it will begin a precipitous decline in function and integrity. If you sit up in your house, do no physical activity, and take in more calories than you need you will indeed become overweight and possibly obese. Again, there may be a genetic predisposition
to having a low metabolism and storing fat, but those who are obese because of a genetic factor, are a very small percentage of the population. If that weren't the case, the rates of obesity today would be the same as they were 20 years ago, or even 40 years ago. A genetic mutation would take much longer than one generation, to cause an epidemic within a population. So, what that tells us is that more than likely the biggest factor is lifestyle
(which includes diet, physical activity, etc). Check this for further reading.............http://www.elements4health.com/physical-activity-can-reduce-genetic-predisposition-to-obesity-by-40-percent.html
Here's the actual journal article for those interested............http://www.ncbi.nlm.nih.gov/pubmed/20824172
Sorry to get on my soapbox but, I just don't want people using "genetics" or a "gland problem" as an excuse as to why people are obese. We need to start getting back to a time when we had physical education in schools, and people ate more often at home (as opposed to fast food three times/week), and did some kind of daily physical activity (even if it was a manual labor job). Hoping for a drug to solve that problem is part of what's wrong with Americans and their health today........................ESPECIALLY Black folks.
