That's right folks. Exercise does NADA as far as weight loss is concerned.
Too many people use exercise as a form of losing weight. You find it everywhere. The problem with this is people are under the mistaken assumption they are burning loads of calories while exercising. Look at the charts all around the web showing you how many calories an activity is burning. What they fail to tell you is that the majority of those calories would be burned just by lying in bed all day long.
There also is a seldom mentioned complication in calculating calories burned during exercise: you should subtract off the number of calories you would be using if you did nothing. Almost no one does that, Dr. Bouchard said. But for moderate exercise, the type most people do, subtracting the resting metabolic rate can eliminate as much as 30 percent of the calories you think you used, he added.
Resting metabolic rates, though, differ from individual to individual and also differ depending on age, gender, body mass, body composition and level of fitness, so guessing at your resting rate also is fraught with error.
Also it has been shown that exercising can actually make you GAIN weight.
Finnish investigators looked at the results of the dozen best-constructed experimental trials that addressed weight maintenance—that is, successful dieters who were trying to keep off the pounds they had shed—they found that everyone regains weight. And depending on the type of trial, exercise would either decrease the rate of that gain (by 3.2 ounces per month) or increase its rate (by 1.8 ounces). As the Finns themselves concluded, with characteristic understatement, the relationship between exercise and weight is “more complex” than they might otherwise have imagined.I'm not advocating sitting around on your duff all day doing nothing and expect to be healthier. Exercise in and of itself is good. The release of endorphins gets it an A+ in my book. It just makes you "feel" better.
So in this New Year, make exercise a regular part of your routine. Just do it for the right reasons. Not because you want to lose a few pounds. That strategy may back fire on you.
