Do you eat every night in front of the television?
Gaining weight is hard to avoid when we eat in front of the TV.
As long as food is readily available, most of us will continue to eat, well past the point of satiation.
We end up eating more because we simply eat to the pace of the program, or we eat until the program is over.
Eating in front of the TV sets us up to prefer unhealthy foods, because we are exposed to more advertising for unhealthy foods, than commercials for fresh fruits and vegetables.
