Personally I think that the BMI is slanted towards being underweight. But I also agree that it isn't a good index for younger children. The simple response here is for Nintendo to make the calculations optional since they are only useful in a dietary regime and NOT needed at all for any of the game play.

The most insulting part is not being called overweight, but that the game then changes the body shape of your Mii! THAT is just cruel :-)

BMI is not a good judge of most people's fitness levels. Muscle mass has alot of variation, and weigh's more then fat. going simply on weight you will get results such as this..

which can be hurtful or unsettling to people.
There should be an option to turn it off, especially the avatar changes.

people who play games and see themselves as an attractive avatar, can be more motivated, and a lot more confident in everyday life. forcing avatar changes to avatars can be emotionally hurting to people who bought the game just to have a bit of fun with there family. No person would want to play a game where they look ugly.

I can say, as a user of Wii Fit, that I was offended by the game. I'm naturally more muscular than many women. My body fat % is 24% but my weight is 170 for 5'4"... The game showed my BMI as nearly obese made my Mii grow into this hideous fat body. 24% is quite lean for a 35 year old woman and I guarantee I don't look like the offensive round ball that my Mii looks like.

The game should allow you to put in your body fat% if you know it.

I do not see why folks are all upset about you are being called obese on the wii fit. This is something that I know and I am sure that you know too ,you may not want to know it but there it is. My solution is not to check your weight everyday maybe once an month. Don't get offened when you hear that you are fat just do something about it. I am. I love my wii fit.

If you are confident in your body a game's perception of your body type shouldn't bother you. I was up near the obese part, but have lost 10kg and now sit nicely in the Health Weight range. I wasn't offended (more shocked that I had put on that much) and enjoyed having the target of reducing the size of my Mii, which wasn't that much of a change anyway. If you are more muscly, just put in a higher height, which should lower the BMI. How you feel in and out of your clothes is a better indicator than any number.

I actually enjoy checking my BMI on the WII Fit, I've lost 89lbs since last September. My current BMI is 30.56 as of this morning weighing 178lbs.(which is still considered obese) I still have 45 more pounds I would like to lose. Please don't take it seriously, have fun and don't be so hard on your selves! (smile)

My wife came out as anorexic. I came out as a fatty.
We are both shapely toned athletic people.

But look, Nintendo did not invent the BMI system, so the results are not their doing.

The fact that they use the BMI in this way, however, is a bit questionable. They could at least qualify the screen output to indicate that "BMI is but one indicator for fitness, using a simple division of weight over height" (or whatever the hell it does).

Wii Fit rocks. The BMI thing will only make Nintendo look like they lack judgement skills in developing a product. Nobody wins. They should change it somehow, even if its just to satisfy their market (which, by the way, is their raison d'etre).

It is ridiculous that Nintendo have had to apologise for featuring a BMI indicator on a fitness themed "game". The BMI indicator is there so users can monitor their progress, in weight loss and fitness levels, over time. The game is not meant for children only, so removing this part of it would be unfair to others who find it useful. Maybe parents could supervise and reassure their children through this particular section. And if any adults are getting upset, then it is probably because they are not happy with their BMI result!

I really don't care about the "offensive" nature of the comments, but I do take issue with the calculations. I am 5'11'' and wii fit states that the optimal weight for me would be 157 pounds. As a man, that would be totally ridiculous. I would literally be a pole if that were the case. Anyone with muscle would be considered "overweight" in this game.

The Wii fit is wrong... the people who do not see it are the ones where the incorrect measurement is not a involved for them. I also got a very high BMI and a ridiculous recommendation to be 143 pounds as a man who is 5'9". WRONG. I was a Marine, and a football player. I am stocky. In high school I could bench 100 pounds over my weight and now I am beyond that. The point is, I am muscular.

While it is perfectly ok for the Wii Fit to calculate a raw BMI based on the flaws in the BMI formula, they should NOT provide an assessment that does not change. Everyone should be able to adjust their Mii and their ideal weight to account for build and work upon a realistic goal and expectation for weight loss.

I am not a fat person, but I do have extra pounds to lose. Having the wii fit make my Mii character extra fat and labelled as obese is inaccurate and offensive. All they need to do is allow the ability to take their measurements and realistically adjust them. Nintendo should step up and recognize this. Everyone with a brain knows BMI is not an accurate assessment for everyone.

I do P90X as a workout most days of the week and am in really decent shape for 40. The wii fit labels me obese and gives me a fat mii. My wife NEVER works out, is not muscular and does have pounds to lose (she will admit it, she is not fat, but like me, losing 10 to 20 pounds would be good)... and yet the Wii states she is in ideal health for her age. BMI is not a way to accurately assess anyone's fitness level.

Again, the issue is that someone who is not fat has to endure having a Mii character that is huge and inaccurate and they have no way of having their Mii be accurate. Is it a major thing? Not really, but who enjoys looking at a big fat Mii character of yourself. It really IS offensive and bothersome when you know it is not true. Inevitably, family and friends will laugh about it too... and yeah, you laugh along, but it is not really all that funny, it is just poor product development on Nintendo's part.

This may hurt some feelings, but it is the truth. I am a 44 year old woman who was 160 and 5'4 and I was*fat*and I knew it!I began the wii fit and it told me, quite accurately, that I was overweight. I exercised and did yoga on the wii fit, graduated to EA Sports Active and Biggest Loser programs. Today my favorites are still EA Sports More Workouts and Biggest Loser for Weight Loss Yoga. I am now 122 lbs and 5'4...much more in the healthy range. 170 at 5'4 is not healthy, even if you have some muscle, as I do. I eat right, feel great, have energy and motivation and am very proud of my journey!

My boyfriend is 6'1" -his "ideal" weight is suggested at 166 lbs - BMI close to 30%. Not even close - it is funny to see his chubby Mii character, but frustrating that it is so inacurate & can't be fixed.

This wretched device showed my BMI as 26% and that my weight of 155 at 65" is obese! However as a member of the military I am below my max weight of 165lbs before I'm considered too heavy. I'm in better physical condition than most folks. It's too bad that the Wii shows me tubby looking.
