It amazes me sometimes how often it seems to occur that when I read some of the latest studies into weight loss, philosophies Slimxpress has been touting for years are consistently proven to be accurate. The latest is a study into exercise’s role in weight loss, and particularly why it seems that the more we exercise, the less we lose.
Researches at The Univeristy of Copenhagen dug into this problem in a recent study. The New York Times reports that the researches gathered a group of overweight, sedentary young men (in their 20s and early 30s). From this group they divided them into three groups:
The first group was a control and were told not to alter their diet or activity habits.
The second group was told to keep the same diet but to do moderate workouts daily, the goal being to burn on average 300 calories.
A third group was instructed to perform more rigorous workouts daily, burning 600 calories.
All groups kept detailed daily food journals. The results were surprising to none of us who have tried to burn fat with intense workouts:
At the end of the 13 weeks, the members of the control group weighed the same as they had at the start, and their body fat percentages were unchanged, which is hardly surprising.
On the other hand, the men who had exercised the most, working out for 60 minutes a day, had managed to drop some flab, losing an average of five pounds each. The scientists calculated that that weight loss, while by no means negligible, was still about 20 percent less than would have been expected given the number of calories the men were expending each day during exercise, if food intake and other aspects of their life had held steady.
Meanwhile, the volunteers who’d worked out for only 30 minutes a day did considerably better, shedding about seven pounds each, a total that, given the smaller number of calories that they were burning during exercise, represents a hefty 83 percent “bonus” beyond what would have been expected, says Mads Rosenkilde, a Ph.D. candidate at the University of Copenhagen who led the study.
