Interestingly Steve it's still a sign of wealth to be fat in the Phils, that is something that makes me quite sad.
The fat content in the diet of the average 'skinny' poor Filipino family is much higher than that of many of fat westerners but there is a reason for that which is simply cheap access to energy, at 9 calories a gram it's better value for money for most folks, indeed I cringe when I see all the chicharon and the likes over there.
When I am in the Phils I always lose a lot of weight, I find the heat suppresses my appetite apart from anything else.
