FWIW, my reading of the tea leaves is that fat alone is fine, sugar alone is bad, and sugar+fat maybe worse. The basic logic of the anti-sugar sentiment is this: Excess of blood sugar is toxic and so it triggers a shot of insulin, intended to drain sugar from the blood and hide it in various places: the muscle tissue, the liver, and last resort - the fat cells. Normally it works just fine, but sometimes the system gets overwhelmed with a big sugar rush and starts producing too much insulin, draining too much sugar, overshooting the target, causing hunger, craving for more sugar, and eating more sugar. The human then goes into the infinite loop of sugar binging accumulating fat on the go. Now if you add dietary fat into the mixture it's possible that the fat cells will suck it up too. That I don't know for sure.
