When it comes to losing weight, so much of it is mental. It requires the conscious decision to begin exercising and eating right. It requires a mental commitment to following through on reaching your goals. And, above all, it requires using your cognitive ability to make educated choices. Still, we are human, which means that we make errors in judgment from time to time. As a result, we sometimes think we are doing something healthy, only to later learn that it wasn't nearly as healthy as we thought.
This mistake occurs most often when it comes to food-calorie estimates and exercise-calorie burning approximations. Allow me to explain ...
in many cases, people think that a certain food has, say, 500 calories. But, in reality, that food actually has twice as many calories. The same misstep happens quite frequently with exercise. Someone will think that the half an hour of moderate jogging they spent on the treadmill burns a certain amount of calories, only to be rather disappointed when they see that it burs far less than they expected.
To help you gauge where your own accuracy lies with this sort of thing, I've compiled a short list of foods (source: University of Pittsburgh study) that demonstrate the average miscalculation people have in estimating the impact each has.
