This makes me a bad parent?

I am a strict vegetarian. Meaning I don't eat any thing but vegetables and fruits. I don't eat junk food and i seldom eat sweets (maybe only once every two months). I don't force my vegetarianism on my kids because I let them make that choice on their own. However, I don't allow them to be inactive or overweight. All of my children who are able to participate in sports have no option but to find something they like and do it. Not just one thing but at least two. My cousin said that makes me a bad parent for not giving my children an option if they want to play sports or not. How is that bad?! My wife's side of the family is the one who thinks this. Yet they don't think what they are doing IS bad parenting. His daughter is 13 and weighs over 180 pounds! And that is suppose to be ok? He said he lets her choose what she wants to do with her life. I have no problem with that, but what I have a problem with is him not encouraging her to be healthy.
