Interesting points to mention - I myself am overweight, and have been - as is my wife. I ws before I started becoming vegetarian, but due to the fact that with being vegetarian, carbohydrates are much more readily available (pasta, breads, etc)
The factor to look at is pretty simple. I'm overweight and a bit unhealthy as a vegetarian, but the person next to me is overweight and unhealthy as a omnivore. OR, is not overweight but consumes very high amounts of bad cholesterol, fats, hormones from meat, etc.
However I do eat my fair share of vegetables, fruits, etc - but I unfortunately know few other vegetarians.
Anyway - I think the point I'm trying to get across is that even if someone is overweight, it doesn't mean they're unhealthy, just as if someone is skinny it doesn't mean they're healthy.
It'd the total package that counts and matters in the end. I don't exercise enough, I know that- however if I did exercise a bit more, even being a bit overweight, I'd still be healthy
