We live in an obesogenic environment. But what does that mean? It’s a concept that’s gathering a lot of attention these days. The word obesogenic comes from combining the word “obese” with the suffix “genic” – to produce or generate something. It attempts to describe the condition of our modern society and how it contributes to the obesity epidemic.

As humans we are very efficient creatures, built to defend our weight. The increase of obesity rates in America can, in part, be explained by the disparity between our sedentary lifestyle and the genes that once helped our ancestors survive famines. You might say that our genes load the gun, but our environment pulls the trigger.

The rapid increase of technology, and the subsequent conveniences it brings, has dramatically shifted the typical environment and lifestyle of most Americans:

• Many of our cities are built for driving rather than walking. Public transportation can be inconvenient.

• People are working in increasingly sedentary jobs and enjoying sedentary leisure activities such as TV, video games, and surfing the web.

• There are safety concerns that lead many to forgo outdoor activities such as cycling or walking, and this affects children and adults alike.

And our environment isn’t the only thing that is changing. Over the past few decades the nature of food itself has changed significantly:

• Food is plentiful year round and inexpensive. Cheaper, less healthy, processed foods are eaten more frequently. In fact, Americans spend far less of their disposable income on food than other any other nation.

• Consumers are inundated with advertising messages hooking us on unhealthy foods and creating bad eating habits. In one year, an average child will watch about 10,000 commercials touting food and beverages.

• Portion sizes are out of control! In 1955 McDonald’s French fries were 210 calories for a 2.4 oz. serving. In 2004, McDonald’s fries were 610 calories for a 7 oz. serving. In 1916, a Coca Cola was served in a 6.5 fluid oz. bottle containing 79 calories. Today, a 16 oz. bottle of Coke has 194 calories.

With both our genes and our environment fighting against us, the outlook may seem bleak. But understanding how these two factors, our genes and our environment, go hand in hand is the first step in the right direction. By acknowledging the environmental factors that may fight against you, you can make healthier decisions and fight back.

This is just as important for those who have already had weight loss surgery, or have committed to a medically supervised weight loss program, as it is for those trying to lose weight on their own. Bariatric surgery and medically supervised diets are excellent, safe and effective tools that go together with new habit formation and positive lifestyle change to produce long-term weight loss.
