Ummmmm....hard to say.
I don't do shit now, eat fairly healthy, have a somewhat physically demanding job and I'm 175 lbs.
I don't feel like I'm obese by any means, but I could loose 10 lbs pretty easily.
Long boring story short....
I went in for a physical for insurance reasons about 10 years ago. This was back when I was running 50-60ish miles a week and racing marathons and half marathons at a fairly high level for an old white guy.
I'm 5' 8" and at the time I weighed in at a whopping 140...
