I think the most important thing to consider is the mentality we subject ourselves to when doing cardio. The point of burning calories is not to replace those calories with more food - particularly foods that are low in nutrients and high in unhealthy fats, unhealthy carbs, sodium and unnecessary sugars. Just because you supposedly burned 200 calories on the treadmill today does NOT mean you should go and eat a whole candy bar that's the same amount of calories. It's not just about calories in vs. calories out. What's in the calories you're consuming makes a HUGE difference when it comes to weight loss. I mean, maybe you do yard work each day and burn an average of 500 calories each time. But do you really think that eating cheese burgers that are 500 calories won't show up on your body just because you supposedly "burned" that food off?
I came across a body building forum about a week ago while researching nutrition science degree programs. There ways a guy who referred to women who do mostly cardio as "cardio bunnies" and proceeded to make fun of their attempts at weight loss. While I don't appreciate his slight to women who focus on cardio, he made a very valid point in all of his sexist talk. Many people who do cardio often make the mistake of thinking that burning calories earns them the right to eat whatever they want. I can have 2 huge slices of cake if I burn 600 calories today. That's the wrong way to think, and I completely agree with that guy on that point. If your only purpose for jumping on the treadmill is so you don't have to feel guilty come Thanksgiving, think again. It's what's in your "calories in" that truly counts. You won't lose weight by replacing the calories you burn with unhealthy, greasy or processed foods - no matter how many calories you burn in a day or week.
I think the point of this article isn't so much to cast a negative light on cardio machines as it is to make us really think about the mentality we take on when using those machines. It is highly likely that they aren't as accurate as they could be for several reasons. Knowing this, it isn't a good idea to assume that you can jump on for an hour, supposedly burn 300 or 400 calories and then turn right around and eat a few slices of pizza from a fast food place. To lose weight, you need to consume less empty calories AND burn more calories. Otherwise, that cardio machine will barely help you maintain your weight, and the emptier the calories you take in, the less energy you'll have to even completely a truly intense workout.
