Another reason so many of us are overweight is that our daily living activities are no longer "activities" in the true sense - that is, we took the "active" out of activity! Our society no longer is a manual labor-driven society. We don't spend all day out in the fields growing our food.
In fact, most of us spend all day indoors, sitting down. Then we leave the office and go home, to sit down some more. Then we expect to spend an hour at the gym every couple of days, and lose weight.
This is a backwards approach to fitness. Our bodies were meant to move - all the time! Being confined to a chair for 8-10 hours a day, and of course sleeping 7-8 hours per night, doesn't leave much room to be active. Obviously for the majority of us with desk jobs, it might seem there is not much we can do about this....
