Sumo wrestlers put on weight to be the best in their sport - wrestlers have to be heavy to be considered strong. But is it a good idea?
Jockeys also have to watch their weight to make sure they're not too heavy so their horses can run as fast as possible.
Like sumo wrestlers some spend their whole career on a special diet, watching what they eat.
But do you think it's right to dramatically change your weight to be the best in your sport?
I think it's good that sumos are carrying on a tradition but putting on weight is silly and for their health it's dangerous.

I think children should not put on weight and do it because they will have serious problems when there older.

I think that if sumos want to be that fat then let them, it's what they want to do so we should not interfere with their beliefs. They may face heart or other problems when they are older but if this is what they really want to do then people shouldn't interfere.

I think that they should carry on doing it because that's what they want to do as a career. If they want to be unhealthy, let them carry on with it.

I don't think sumos are that fat! They are a little (well quite a bit) chubby and have a plump stomach and legs but I don't see what the big deal is!!!!

I don't think we should judge them because they are only doing what they want and they are probably really good people inside. If they want to get fat and look disgusting for their career then fine.

It's their tradition so we should let them get on with it.

It's a tradition and has been going on for years and if they want to represent their traditon then good for them.

Even though it's part of Japanese tradition, I think the weight factor of sumo could lead to health problems in later life.

Of course sumos are fat - it's their life!!! It's pretty unhealthy though.

I think sumos are way too fat but it's their choice and their problem. I think they should talk to someone about it before they start if they're still a kid, but adults are responsible for themselves and it is their choice. You shouldn't treat them any different though.

I think the people who do sumo wrestling are a danger to themselves health wise, but they are old enough to make their own dissions, and I also think we should not judge people by their appearance. Although I would never try to be a sumo!

I think the health condition of these people is very bad, and they are doing this just for money.
Saqib, 11, Luton
I think that sumos are fat, but it's their life and if they feel that they need to make millions from wrestling at the risk of their lives, we should accept it.

If you're over 16 you can do anything with your body. It's their choice if they want to put on weight for their sport but they'll face the consequences in their later life.

Just thinking about sumo wrestlers makes my stomach churn. Just looking at them is disgusting, they all need to go on major diets. They may think it's cool, but their parents or a teacher should warn them of the terrible consequences.
Sarah, 13, Ireland
I think they should do what they want for themselves, it is their life and they should chose what they do with it, if they want to get fat and have health problems it's their choice.

People should not question the ways of Japanese culture. I agree that young sumos are unhealthily obese, but if no young children do not get invovled with tradition then it would die out.
Simon, 12, Lincoln
I think they are just wasting their lives by getting heavy and they will probably get heart problem sooner or later!
Megan, 10, Wisham
Sumo wrestlers are wayyyyyyy too fat! They need to go on some BIG diet cos that weight is gonna take ages to come off!
Saira, 11, Liverpool
We shouldn't judge people by what they look like but it is also true that it is unhealthy to be overweight.
Katie, 14, Bristol
I think its really unhealthy and could lead to dangerous or even fatal consequences.
Sinead, 12, London
I think sumo wrestlers are too fat but it's up to them if they want to join a sport like that.
Lucy, 10, Kidderminster
I think your health comes before sumo wrestling. What is the point of sumos any way?
Laura, 12, Gosport
I think it's unhealthy what they are doing. They could be risking their lives.
Lucy, 14, Bristol
As long as you're happy about the way you look and feel good about yourself, I don't think it matters. Though health is also a very important issue but is your own decision.
Laura, 12, Hinckely
I think that it doesn't really matter that much, as they need to put on weight for what they are doing!
Carys, 11, Redhill
In the past I have suffered from weight problems so I think that it shouldn't matter what your weight is. If you have a talent use it and take part in whatever sport you like!
Bryan, 11, Fermanagh
I think it's entirely up to you how you look and no one should tease you about it.
Laura, 11, Bromsgrove
If it's for sport then it doesn't matter, providing it doesn't hurt you.
Ros, 11, Cheltenham
I don't think it matters what weight you are as long as you are healthy.
