Fat is the second easiest form of calorie to break down, but it’s also fairly important component of the body. It takes the longer than carbs and requires the more energy to break down because the body has to refine fat through the galbladder and lymphatic system.

Chylomicrons are the result of fat digestion and they’re sort of like a bag of stuff. Your lymphatic system takes a bunch of the stuff for the purpose of fighting infections. Your bones and skin take stuff. Basically these “bags” pass around in your blood until all that’s left in cholesterol and then that (hopefully) gets collected and processed by the liver.
