It would appear so. But is there a problem with eating carbohydrates
when your weight is normal and you take adequate (much) exercsie?
I didn't think so, and a huge population of Asian rice eaters seem
healthy enough :-)

Well, as the composition of the diet is rather irrelevant to fat
storage status (weight is so often confusing people as it can be
water, muscle, bone, fat, glycogen and so on).
Fat store status is surely an artefact of energy balance.
But anyway, why must I accept that a "high fat diet is effective for
weight loss" when I claim that fatty acid problems are an artifact of
being overweight. What is the connection? I can't see it, I'm afraid.

But much less exercise? What weight loss and caloric intake were
involved here? By this, there should be billions of Asians in big
trouble.

Well these Asians eat a relatively vegetarian diet. A pile of rice
"flavoured" by the meat/vegetable side dishes is typical.

Absolutely. However I often wonder what the dietary needs of
westerners would be if they had never overeaten (anything -- fat or
carb) and they all did heavy exercise every day. Just like it is
reasonable to assume we evolved as.
