Floaters are supposed to be more healthy, aren't they? Lots of fibre and all that.
I always thought floaters were due to too much unabsorbed fat.
Or air bubbles maybe...
Shall I just stop now, or is it time for the Bristol Stool Chart?
You are correct. Floaters show a high fat diet, whereas high fibre diets are sinkers.
I know my shit... 
You are Gillian McKeith AICMFP!
Oh no! Your quote of my quote now conveys the wrong answer....
So
Correct answer...FLOATERS = HIGH FIBRE DIET, not high fat diet
Ahem...It can be both. In vegetarians, stools may float for the reasons you have given.
However, in meateaters, floating stools usually indicate too much fat - omnivores' stools should generally sink (although some floaters may occur at times of high fibre intake). Faeces tend to become floaters in malabsorption states, particularly when increased quantities of fat enter the colon and are then available for bacterial degradation. This also results in increased quantities of gas being present in faeces, which accounts for the fact that faeces float when there is fat malabsorption. In steatorrhea, for example, one of the classic sympstoms is the floater.
I would refer the Honorable Member to the Tripdatabase for Evidence Based Medicine which has a whole section on 'floaters'...
