 With a likely low metabolic rate, a large body size, a consequently reduced energy requirement for its weight, and an extraordinarily large gut that likely had a foregut fermentation site, "Glossotherium" could probably survive better on foods of lower nutritional value than other sloths could.Though it is likely "Glossotherium" primarily ate grasses, it also probably ate a variety of foliage as well and would be better considered a “browser-grazer” than simply a grazer.
