Fats need to be broken down into fatty acids and glycerol before entering the bloodstream. 
Fats are large insoluble molecule and therefore would not be able to pass through the membrane of the gut (where you have the lacteal which inside the villi) neither the bloodstream. Remember the capillaries themselves are one cell thick. Large molecules can not pass into bloodstream. They must be digested. 

Consequences would be serious because that would mean without fats reaching the cells in your body it wouldn’t therefore be able to provide the body energy and insulation. Fats are needed in the body to keep you warm. 

Same with carbohydrates and protein.

Fats molecules are too large to be absorbed into the blood stream inside the tiny capillaries which would get clogged by them.
