What are the effects of consuming a diet made up mostly of fats? there is more than one correct answer; select all the correct answers?

Though they are an exception, the Inuit traditionally ate a very high fat diet from coldwater mammals like walrus and obtained omega - 3 fatty acids from it and fish oil and had a very low incidence of cardiovascular disease.

Interestingly enough though is Dr Atkins diet which is a low carb relatively high fat diet.
