The Obesity Question: Too many calories in or not enough energy out?
September 28, 2011
It’s too many calories in, according to the research - as surveyed by the Sightline Institute. Here are some items from research director Clark Williams-Derry.
Specifically, we find that increased caloric supply accounts for 82 percent of adult obesity in developed countries. Calorie consumption (including eating + waste) skyrocketed in tandem with the obesity epidemic, starting in the mid 1980s:
Calorie consumption was really high in the early 1900s — which I attribute (perhaps inaccurately) to the fact that so many people were doing manual labor, and were actually burning an extra 1000 calories or so per day in hard work.
.
Healthy food got more expensive over time. Calorie dense foods — refined sugars, starches, oils — are really cheap. Calorie-for-calorie, healthy foods like salad cost 10-100 times more than junk food.

- using food as an emotional crutch (as often depicted on television)
