Like Mindi, here's the quote that caught my attention:
"If everyone exercised, there would still be a wide range of individual body sizes and shapes," said Steven Blair, PED, President and CEO of the Cooper Institute in Dallas and renowned exercise researcher. "There is a genetic component for weight, just as there is for height."
I've NEVER believed the notion that 3500 (extra) calories burned = one pound of fat lost. It ain't that simple.
This article glossed over the details of the studies cited, and I didn't see whether or not the people in the exercise plans were required to (and actually DID) honestly record the calories they ate as well as the exercise they performed. Any successful and long-term weight maintenance is a combination of the two: consistent exercise and managed eating (for those of us genetically blessed with a tendency to gain weight).
Seems to me that our individual bodies have subtle ways of maintaining the genetic script. If we engage in more exercise, we may very well tend to eat more, whether we notice it or not. That's why journals are one of the more successful techniques for weight loss and maintenance.
I've heard health buffs complain that nobody should "exercise"--we should all get our activity from sports, work, and other regular daily exertion. Unfortunately, that's not the way the modern world works.
I'm convinced that exercise as an anti-aging, health promoting, weight management routine is very well worth the effort. So stop reading this thread, and go hop on a treadmill or something!
