I respectfully suggest that those people do not have enough of anything to eat to trigger the insulin response and are, as such, irrelevant for the purposes of this issue.
I am talking about those of us for whom consumption of carbs has a disproportionate affect on our insulin response, and thus our fat storage.
And that is why you also see people in Africa, eating a high carb diet, with very little else, who are over weight and malnourished at the same time. Their bodies cant use the high carb diet they are given and automatically stores the food. Its a well know phenomenon in feeding stations. This is different from the swollen stomachs of starvation.
