Last month, TIME magazine ran an article which claimed that due an increase in post-workout appetite, exercise is not an effective weight loss technique.
Understandably, this created a furor in the fitness/weight loss industry.
Fitness gurus were seen all over tv and the internet sputtering about how the author didn’t have his facts straight and that he didn’t know what he was talking about and blah, blah, blah.
Essentially, they were worried that they were going to lose business because of this article.
And they probably did.
But, was it fair? Was the article correct? Is exercise ineffective as a weight loss tool?
Let’s look at the science.
The TIME article was based on the findings of a single study conducted on obese, postmenopausal women.
The study concluded that:
In this study of previously sedentary, overweight or obese, postmenopausal women we observed no difference in the actual and predicted weight loss with 4 and 8 KKW of exercise (72 and 136 minutes respectively), while the 12 KKW (194 minutes) produced only about half of the predicted weight loss.
However, all exercise groups had a significant reduction in waist circumference which was independent of changes in weight.
So, let me get this straight.
- The majority of women in this study lost weight as predicted.
- And all of the women saw a reduction in waist circumference.
And the author neglected to mention that postmenopausal women are prone to weight gain due to hormone changes. Much more prone to weight gain than the majority of the population.
It’s almost like the author of the article started with a conclusion and went looking for some research to back him up.
Perhaps he should have wrote about this study, which shows that exercise improves:
- body weight,
- waist circumference,
- body fat mass and percentage,
- insulin sensitivity/resistance,
- fasting blood glucose,
- fasting serum insulin
- and systemic inflammation
Perhaps they should have written about that study
