Simple or Complex?

Work with your genetics, don't hide behind them!

Below is an article I saw recently concerning obesity and weight control. It is interesting, but in my opinion reflects the growing attitude that people are victims and are at the mercy of some unknown forces beyond our control. Of course it's obvious that genetics has a whole bunch to do with our physical characteristics. We all know that some people can eat anything and everything and never get fat. We also know that there are some who, in spite of great effort, struggle much harder to keep their weight under control. Still, there is much more that we can control than not. True diseases effecting metabolism are rare. Blaming obesity on a virus is like blaming sexual immorality on some "disease" called sex addiction. Really, is it more complex than energy expended vs. energy intake? No doubt some seem to burn calories easier than others. Newsflash: Some people can run faster than others, Some can lift more, and some can sing better. The bottom line is we never know how far we can go with anything until we have invested a lot of time and effort. Some people will have to work harder, longer, and sacrifice more to get the same results. Not a new concept there. Quit looking for excuses and focus on how to improve within the parameters that are inherently ours.

When the American Medical Association classified obesity as a disease, Nikhil Dhurandhar, a researcher and vice president of The Obesity Society, said he welcomed the news as an acknowledgment of the challenges people face fighting the battle of the bulge. But he wondered if the declaration went far enough.
Like a growing number of experts, Dhurandhar believes the accumulation of excess fat is likely to have multiple causes beyond a potato-chip-and-couch-potato lifestyle.
Dhurandhar likens obesity to other chronic diseases. Just as the term cancer covers the numerous conditions that occur when abnormal cells divide out of control, obesity may not be a single disease but rather, a group of diseases tied together by the symptom of too much body fat, he said.
"It may look the same on the outside, but what triggers the condition varies from person to person and may require a different treatment to control," he said. "Down the road, we need to figure out why people become fat and then tailor their treatment to address the underlying causes."
Dhurandhar's own studies at Pennington Biomedical Research in Baton Rouge, La., focus on obesity-causing viruses. He discovered the viruses in chickens back in the 1980s and has since associated the presence of certain viral antibodies in the bloodstream of humans to increased body weight.
In one of his landmark studies of 500 people, 30 percent of the obese patients tested positive for the virus, compared to only 11 percent of the lean individuals.
Dhurandhar is quick to point out that he doesn't believe most obesity is infectious in nature, but said that the discovery of a "fat bug" should be a wakeup call to researchers, physicians and anyone struggling with their weight that there may be more to shedding surplus pounds than simply cutting back on calories and putting in a few extra treadmill sessions.
"What good does a starvation diet do if obesity is caused by a virus?" he asked.
Beyond viruses, scientists have identified at least 84 other potential contributors to obesity, Dhurandhar said. They range from genetic to biological to psychological to environmental. Currently, there are about a dozen of these obesogenic culprits under serious study in labs around the world, he noted.
For example, numerous studies now associate lack of sleep with an expanded waistline. Other studies have found that exposure to certain insecticides and plastics disrupt gut bacteria, which may stimulate appetite, slow digestion and accelerate fat storage. And some studies propose a link between the lifestyle habits of great grandparents and their great grandchildren's weight status.
"Not all the causes will wind up being treatable or preventable -- you can't do anything about what your great grandparents ate -- so we will have to focus our efforts on the ones we can control," Dhurandhar said.

Christopher Ochner, director of research development and administration at the Mt. Sinai School of Medicine in New York said he agreed with Dhurandhar's idea that there could be multiple contributors to obesity, but said it complicates matters to classify obesity as multiple diseases.
"At the end of the day, we still have the law of energy balance to contend with," he said. "If you ingest more than you expend you are going to gain weight, period."
Dhurandhar conceded that eating and exercise play a significant role in obesity, but said that role is not as well understood as the general public thinks.
"We've focused almost all our resources on the so-called 'Big Two' of diet and exercise for more than 50 years and it hasn't helped," he said. "We will have to move beyond 'eat less and move more' if we want to make progress."
Ochner said he agreed that trying to lose weight and keep it off in the long term by exercising and cutting back on calories has less than a 1 percent chance of succeeding. He acknowledged that the reasons for weight gain vary greatly for each individual and the precise formula for energy balance through diet and exercise is nearly impossible to determine.

"There is literally, there is no difference between an emaciated person starving to death and an obese person on a healthy weight loss diet in terms of physiological reactions," he said. "That is going to be a tough problem to solve."

  1. I know this is an old post, I just wanted to say that at the end of the article you shared one of sources says that focusing on eating less and exercising more "hasn't helped", but in my experience its the ONLY thing that works. One just has to remember that it's a lifestyle change, not a diet or 3 month exercise regimen, which means that if you want to keep the weight off you need to be doing it for the rest of your life.
