Are Poor Genetics Making You Fat? Negative Genetic Nutrition and Diet Factors Which Lead To Obesity

Do you have obesity promoting genetics in this obesity promoting world? It doesn’t matter if you are rich or poor obesity is an epidemic and it is on the rise. The convenience and price of low-quality high calorie processed foods has not helped with this. Along with that many of our jobs and lifestyles allow us to be more sedentary than ever before. Being overweight is a matter of energy balance as long we are consistently taking in more calories than we are expending we will gain weight. But some have always had a tendency to carry a bit more body fat than others. Which logically leads us to believe there is a genetic connection.

Are Poor Genetics making You Fat? Negative Genetic Nutrition and Diet Factors Which Lead To Obesity
I wanted to say that there is no one gene in the body that can cause obesity, but it turns out that in fact is not true. According to the Centers for Disease Control and Prevention although it is extremely rare there are in-fact nine different genes that on there own can cause obesity. The most common one is MC4R and this affects less than 5 percent of obese people. It causes people to have uncontrollable hunger. It was one the genes that was tested for in my DNA test that I got done, but more on that in a minute.

For most obese and overweight people there is no one gene. In fact there are over 400 different genes associated with being overweight or obese, with only a handful being major players. Now with my DNA test I did with tellmeGen they tested 8 genes or regions directly related to obesity of which two came up giving myself an increased risk of obesity, the others we normal and they tested numerous other genes relate to my ability to process foods as well as my preference for sweets.

By the way I will be announcing the winner of the free DNA testing kit from the last video at the end of this one.

When it comes to my preference for sweets you may have heard my story on how I could never leave a gas station without purchasing at least 2 chocolate bars and before I got myself into shape I could polish off 8 donuts in one sitting no problem. So I was a little surprised to find out that my preference for sweets was normal.

One of the most common gene variants connected to obesity is the FTO gene. It increases your risk of being overweight or obese by 20 to 30% and was one of the ones I was tested for although mine came back normal. But there is a reason I bring this one up specifically, is as we start to see these different gene variants stack up we might feel like the genetic deck is stacked against us and there is nothing we can do, we were dealt a losing hand.

They did a meta analysis of over 200,000 people with this gene and looked at how physical activity affected the genes influence over a persons tendency to be overweight and found that physical activity reduced the odds of obesity in people by 27%.

These people were people with active jobs or people who spent at least an hour a day doing some sort of activity. They weren’t people who were doing progressive fitness programs, nor was diet taken into account.

Now our society is obesogenic. Which means our society tends to cause obesity just as much as our genetics. With easy access to food wherever we go. You go to the lumber yard to buy some construction materials and there right by the till is pop, chips and my nemesis chocolate bars. It’s hard to remember a time when there was gas stations without a convenience store attached to it.

Men eat on average 168 calories more per day now than they did before 1970. To put that into perspective that adds up to about 17.5 extra pounds of excess body fat gained every year.

So while we cannot control our genetics and our large scale environment has changed. We can make effective changes in our day to day lives that will offset these negative influences. Things like improving our food choices eating more whole unprocessed foods, and taking some time everyday to be more active even if that just means going for a walk.
