Is Exercise Twice a Week as Good as Six Sessions?

If you’re not familiar with weight training, a personal trainer is an great idea

Weight Maven Beth Mazur  found evidence in favor of the fewer days, at least in post-menopausal women.

I don’t like to exercise. Sometimes I find excuses to avoid even my twice weekly 40-minute workouts. I do enjoy hiking; I even hiked to the bottom of the Grand Canyon and back out last May. But that’s not exercise, it’s more recreation.

You may well have good reasons to exercise every day. Maybe you’re a competitive athlete or enjoy exercise. If you just want the health benefits of exercise, I’m increasingly convinced that twice a week is enough.

How Has the U.S. Diet Changed Over the Last Century?

 Beth Mazur over at Weight Maven has posted a lecture by Dr. Stephan Guyenet in which he outlines the changes in American diet over the last 100 years.  It’s only 16 minutes long.  You may  find an explanation for our excess weight problem.

On a related note, Civil Eats posted a cool info graphic showing the sources of calories in the U.S. diet and how those sources have evolved over the last four decades.
