In recent research studies, especially carried out in Canada, it has been found out that the general belief that obese, or overweight, people, are couch potatoes and it is because of this that they are the way they are, may be wrong. Essentially, these studies followed groups of people and compared obese vs normal-weight people and found out two things: first, obese people move more in terms of steps, than normal-weight people, and two, and most amazingly, overweight people expend more calories than normal-weight people simply because their bodies, given their sheer size, have to use more energy to simply move. Thus, these studies showed that, although not by much, individuals with problems of weight do spend a bit more calories per activity, than normal-weight people.
