Ah… Here we go…. From poopreport.com.
“Actually, it is gas that does it. Increased levels of air and gas in the poop make it less dense, and cause it to float. Simple as that. Dietary changes can lead to an increase in the amount of gas produced by the bacteria that live in the gut, which is probably what the vegetarians are basing their whole “perfect stool” theory on. I don’t know—the whole time I was vegan I never consistently produced Floaters.”
Furthermore…
“Conventional medical wisdom attributes Floaters to the amount of fat in your poop. While this IS true for certain diseases (cystic fibrosis, celiac disease, biliary atresia, abetalipoprotenimia and a few other weird sounding illnesses), it is NOT true for your run-of-the-mill healthy person.”

As for the author of said answer… Here’re her credentials
“Poonurse is an RN with 25 years experience in labor and delivery. Her qualifications include seeing a lot of poop, and owning a computer. Also, she works in Michigan, which she calls the asshole of the universe, so that’s another bit of credibility. Got a question for her?”
