Interesting that the current obesity epidemic, as it's being called, kicked off at pretty much the same time as advice to cut down on animal fats became common, and it was advice given to everyone, not just fat people. Low fat foods tend to be padded with sugar and other carbohydrates which, as is being widely recognised now, are far worse, not least because they contain fewer useful nutrients that animal fat do. Animal fats also keep you unhungry for longer because they take longer to break down.
Anyway, I've said enough. I'm just amused by the fact that articles saying advice to cut down on fats was mistaken are becoming more common.
