The amount calories/energy expended from an hour or two hour gaming session is no substitute to physical exercise of one or two hours per day. Video games should be used as well as regular daily exercise. Also a balanced healthy diet lifestyle will help to counteract the growing obesity epidemic that is sweeping the western world. Children and adults generally eat too much processed food and  do not eat enough fruit and vegetables and do not drink enough water. Excess sugar, fat, salt and preservatives/additives are huge culprits in the increased number of overweight/obese people within society.

Children and adults in the modern age live a far more idle/sedentary lifestyles in comparison to previous generations and they are exposed to, too much technology.  Video game screen time should be limited and physical exercise and healthy diet/lifestyle should be encouraged. Video games are traditionally seen as a form of entertainment rather than a form of exercise.

From my personal experience I found  motion comntrol interactive games to be light to moderate exercise that barely increases the heart rate  and rarely makes me sweat. Cycling, jogging, walking and swimming burn up more calories/energy. The younger you are the more energy you can burn from exercise and you have a faster recovery rate. Interactive motion games may be a good start to an exercise/weight loss program. More strenuous physical activity requiring physical exertion or physical labour intensive work will improve fitness, increase strength and stamina. 

Pretty sure that's been the whole idea behind it.

And I still managed to switch from obese to normal weight with WiiFit alone.

and I managed to lose 40 pounds in a few months without doing any kind of exercise.

Try Your Shape Fitness Evolved on Kinect and then tell me that.

My girlfriend just began doing something for her body with Your Shape Fitness Evolved 2012. Though the info screen says the same as the OP.

The Fight on PS3 is good exercise. If you put an hour into it and get into the fights, it's both fun and demanding.
Actually, one hour every day of that game is guaranteed to make you fitter if you need to get fitter. It's far from a substitute to a fitness program, but it's also far more than just pretending to work out.

For a self conscious fat person, starting out in the living room where there is no one to mock you can be a good think. Just don't stop there.

I can see a future in which to be a competitive CoD player you will be required to be fit so you can keep up in on the omnidirectional treadmill that controls your virtual self in the game.

I disagree, as your statement is flawed at the premise that motion games are not exercise. If you play Just Dance on Wii for an hour a day - that's a lot of aerobic, fat burning, exercise right there. Wii Fit includes many anaerobic exercises which help build muscle. These are regular exercises, and it you do them regularly in combination with a proper diet (balanced and with no American food), then you will be very fit.

thats great to hear mate, hope you continue. you should go to gym now go get those muscles stronger.

I wish someone told me this SIX YEARS AGO. I guess I haven't exercised in 6 years then...
