He doesn't seem overweight for me.
While I feel for the family, to say that he is not overweight shows just how much society's perception of being overweight has changed.
Take a look at this picture, for instance.
And take a look at the body fat visual chart for comparison.
With the overhanging belly, he is easily 35-40% at least. While the majority of people today are fat (especially in the US), that is not healthy. If anything, until recently, 20-25% used to be average.
Above 25-30% is the fat territory, and that's when you start increasing your risk for heart attacks, diabetes, and strokes. Mr. Goldberg may have had a lot of things going for him, but he is most certainly more than a little overweight.
Assuming he's ~6 feet, I would argue that he is probably ~30-40+ lbs overweight. That is not at all healthy. I'm not arguing everyone should have abs, but there's a happy medium here. Mr. Goldberg is very clearly on the unfortunate side of the medium.
