While the researchers emphasized that eating junk food is still certainly unhealthy, they concluded that the overwhelming majority of weight problems are not caused by consumption of soda, candy and fast food alone. Rather the problem is that many Americans are just eating too much and not exercising enough. For example, the researchers note that the average daily calories consumed in the U.S. in the 1970's, before the obesity epidemic took off, was 2,039 -- compared to the average of 2,544 consumed circa 2010. The results, the researchers say, have big implications for how we think about food and weight gain. "If you're thinking about this as a dieter, more than likely if all you're doing is cutting out junk foods it's not going to have much of an impact," Just said. " More importantly, if you're thinking about this in terms of food policy and how to encourage people to have healthier diets and be a healthy weight, targeting narrowly these foods probably isn't going to do it. It's more complicated than that. It's our entire diet."
