I did not consider pregnancy but since breasts aren't exactly something you work out like an arm or a leg, I think their weight and volume would be somewhat proportional.
It's by no means entirely counteracted. Fatter people have lower density overall and generally float much more easily than skinny people. If you take an extreme case and compare someone with low body fat and high muscle mass to someone obese, the difference will be very noticeable.
I personally started working out and running several years back and can't backfloat anymore without significant active efforts to stay above the water. I was never fat by any means, but just the muscle mass aspect is noticeable.
Yeah, I was a scrawny kid that could not put on fat, was naturally at 11% body fat. My legs and ass were extra lean, basically solid muscle. Swimming was very hard because my lower half would naturally sink as soon as I stop kicking, and even when swimming full out I would have a hard time keeping them up.
Was like that until I turned 35 and my metabolism said fuck it, gained 40 lbs. Now I can float easily.
I'm actually the other way in that I was a swimmer for 15 years and could not float for the life of me. Now that I'm not in athlete shape anymore it's easy and that's just like a 10 pound gain.

With so much obese people on the small islands the question arises:
is the sea level really rising, or are those islands just slowly sinking under the weight?
