Step away from the doughnut


Physicians--and everyone else in the world--know that diet and exercise are the pillars to weight loss. But a study presented Friday at the European Congress on Obesity suggests that diet is, by far, the main culprit when it comes to packing on pounds, and should be the focus of weight-loss efforts as well, Science Daily reports.

The rise of obesity in the U.S. since the 1970s can pretty much be blamed on eating more calories, the study found. In order to get back to those sleek '70s physiques, adults would need to cut about 500 calories a day from their diets, and children would need to cut about 350 calories a day.

The alternative is to add about 2 extra hours of walking time to your day (2.5 hours if you're a kid). Which doesn't seem very realistic. Exercise is, of course, wonderful for many reasons and should be maintained and promoted, the study authors said. But to really combat the obesity epidemic in the country, Americans have simply got to stop pigging out.
