Exercise: Less Is More
You are probably like most all of us: we'd like to drop a few pounds. And tried and true, we know that portion control, better foods, and exercise REALLY is the key. There's no magic pill. You have to commit. Well, hallelujah there is good news on the horizon!
• A recent study shows that working out for 30 minutes is just as effective for losing weight and staying fit as working out for 60 minutes
• In fact, participants in the study who exercised 30 minutes per day burned more calories than those who exercised for 60
• Exercising for a whole hour instead of a half does not provide any additional loss in either body weight or fat
Published in the American Journal of Physiology, these are researchers from the University of Copenhagen.
In the study, researchers followed 60 overweight, yet healthy men for 13 weeks. Half of the participants exercised for 30 minutes a day while the other half exercised for 60 minutes a day. They were told to excise to a “light sweat” on a treadmill and increase the intensity three times a week. Their effort and activity was monitored with a heart-rate monitor and calorie counter.
I know you're thinking HOW COULD THAT BE?
Participants exercising 30 minutes per day burned more calories than they should relative to the training program we set for them. In fact we can see that exercising for a whole hour instead of a half does not provide any additional loss in either body weight or fat. The men who exercised the most lost too little relative to the energy they burned by running, biking or rowing. 30 minutes of concentrated exercise give equally good results on the scale.
