Our waistlines aren’t expanding because people aren’t exercising intelligently or vigorously enough.

The idea that our obesity epidemic is caused by sedentary lifestyles has spread widely over the past few decades, spurring a multibillion-dollar industry that pitches gadgets and gimmicks promising to walk, run and kickbox you to a slim figure. But those pitches are based on a myth. Physical activity has a multitude of health benefits — it reduces the risk of heart disease, Type 2 diabetes, high blood pressure and possibly even cancer — but weight loss is not one of them. …

The food industry has been central in pushing these misconceptions, using tactics similar to those employed by big tobacco, to elide its culpability in spreading disease. … Reuters found that the food and beverage industry spent more than $175 million on lobbying during President Obama’s first three years in office, more than doubling its spending under the last three years of George W. Bush’s administration, targeting proposals like a federal tax on sodas and stricter nutritional guidelines.
