These folks also have a lot of Kwashiorkor (protein deficiency syndrome) recognizable by bloated belly and skinny legs. In Diamond's Guns, Germs and Steel he talks about how little access they have to protein and that they have to supplement their diet with lots of insects, which I suppose are pretty low fat.

So sure, if you don't mind not getting enough protein, super low-fat is doable, for awhile anyway.

Well... as usual, Denise amazes me. I wonder if I still have a rice cooker? :-)
