Can You Exercise and Still Gain Weight? SPOILER: YUP!

Did the New York Times act responsably when they wrote about a recent study of weight management and exercise?
The article, entitled “Exercising but Gaining Weight,” takes a look at research conducted at Arizona State University, following 81 healthy, but sedentary women who were overweight.

The women participated in a supervised exercise program where they walked on a treadmill 3 times a week for 30 minutes, at a pace that represented 80% of their maximum endurance.

They were told not to alter their diet or eating habits during the 12 week study. At the end of the study, all of the women had significantly increased their aerobic fitness, but many had also gained weight attributed to fat, not added muscle.

Are you shocked? I certainly am not. The average 150 pound person would burn about 142 calories walking briskly for 30 minutes.A 200 pound person might burn about 172 calories in the same time. Do the math, and at best, these people would have lost between 1.4 and 1.7 pounds over the 12 week period. That’s it. Less than 2 pounds!

I would venture to guess that the increase in activity led them to be a little hungrier, and maybe a little more tired, causing them to eat a bit more and move a bit less throughout the day. It’s no surprise to me, that these people gained weight.

I see woman at the gym struggle through a cycling class, only to spend the next hour or two at the juice bar, replacing practically every calorie they burned with carbs. Exercise isn’t a magic pill. Slow, consistent cardio doesn’t burn much fat. To see results, it takes a combination of strength training and cardio with intervals to spike your heart rate.
What you put into your body is of even greater importance. Moving more and eating more, especially more of the wrong foods, is going to cause weight gain. It’s that simple.

A congratulatory post workout snack at Starbucks would run about 600 calories for a tall Pumpkin Spice Latte and a muffin. Try that three times a week and see where that gets you.

I calculate a 6 pound weight gain from that alone!

It doesn’t take a degree, or an elaborate study to come to these conclusions.

Did the Times do a disservice to it’s less fitness conscious readers by printing this study? Does it send a message that exercise isn’t going to help you lose weight so you shouldn’t bother?

While I am sure people are using this study to validate their sedentary existence, I am not going to give up my gym membership just yet.
