So much for the it doesn't help you lose weight.

Over the course of this experiment I wrote over 50 pages of journal entries and impressions. I will now try to break that information down into one short post with statistics, a graph and my “before and after” pictures. 

The truth is it really doesn't matter what you do, so long as you are doing some type of exercise for 30min to 1 hour at least 3 times a week , you will lose weight 

he dnt look like hes lost weight he just looks like hes sucking it in in the after picture! lol.

but congrats to him if he did lose that much weight, altough he didn't have to weight for wii fit, i'm sure there was a gym around the corner...

If you actually follow what WiiFit asks of you I am not suprised, because if I am not mistaken it gives you schedules that involve things like an hour of walking or other things like that (where you are not neccessarily in front of the TV)

umm no. he is mearly pushing out his stomach in the first pic and sucking it mostly in in the second.

Look at face, arms, and legs. All same size in both pics.

he's purposely lowering his chin in before and putting one foot slightly in front of other.

His chest, and everything else beyond the stomach are the same proportions.

I CALL SHINANIGANS!!!!!

Wii Sports worked. OF COURSE Wii Fit will work.

nah he definitely looks like he has lost weight. Though i think he maybe breathing in a bit. This is one of the main reasons the detractors used as to crap on wii fit, but we have evidence here, i think we will have even more experiments like these as soon as wii fit is released

I think this is legit , because you could see in the neck are he doesn't have much of a chin compared to the first pic.

 Look at th angle of his face. If you put your chin slightly down you will look fatter in the neck too.

EVERYONE look at his back just above his elbow, see those two dimples/divots. Those are exactly the same in both pics.

Also notice his facial hair/hair cut. Exactly the same. I would think its pretty hard to ensure they are exactly the same after 7 weeks.

WOW

 His haircut and sudeburns are different in both pics, though that can easily be done.
