This thread: Confused and scared to eat fat has a pretty decent explanation for how fat processes in the absence of insulin. Here's a good quote from it:

So what happens to the fat you eat?? It is WASTED. That's right, wasted. The fat you eat is broken down into fatty acids in the bowel, by the action of enzymes and bile. These fatty acids are absorbed into the bloodstream and taken to the liver, where they are further processed ... into ketones, and into other fatty acid components. Some of the ketones may be used for fuel. Mostly they are excreted in the urine, stool and breath (via the lungs). The free fatty acid components are also excreted. Why?? Because once fatty acids are broken down into the smaller ketone, acetone and fatty esterols .. they CANNOT be converted back into fat. That's basic Biochemistry 101. Without insulin, they cannot be forced into storage in the fat cells. So they are eliminated. This is what Atkins refers to as the "Metabolic Advantage".
The other question is how does eating fat stimulate the burning of BODY fat?? Well, it acts like kindling. It primes the liver into fat-burning and ketone-production mode. Once this ketone production is in full swing, and the dietary fat is used up, the liver starts looking for more source of fat to process. It turns to your body fat stores.

Does that help?
