Fuel for the body

I understand that when you eat carbs, insulin is released and the carbs are converted into glycogen. What happens when I eat fat, then? Is there any insulin response from eating fat, and if not, how does the body get energy from dietary fat?

Thanks. I've got to be honest, that page is way above me! I just need a really simple explanation if possible.

Carbs are a source of fuel. Fats are also a source of fuel but they are a more efficient source. Under normal circumstances fats do not raise blood glucose to abnormal levels but some people report that too much fat for them personally have raised their bg. I eat a LCHF diet rich in saturated fat and see no rise in bg from the fats I eat but if I eat a carb rich food such as bread then my bg sky rockets.

So when you eat fat, it is still a fuel source like carbs, it just doesn't raise insulin?

The simplified answer is that it doesn't raise it as much. However in order for us to utilize fats as energy, background insulin has to be low enough...otherwise we remain stuck in the carbs mode and may be energy deficient. Eg High insulin, low glucose, low ketones.
