I heard that as well. I suppose it makes sense from an lifestyle point of view as way back in the days when they first moved into their island homes it was extremely hard to get fat, so only the rich could do it. And if you wanted to see the next couple of islands, it was a several hundred mile boat trip depending on where you start. And that trip would be done paddling by hand and/or on very short rations/ kind of starving or eating less.
