The CDC says that "Most of the fat that you eat should come from unsaturated sources: polyunsaturated fats and monounsaturated fats. In general, nuts, vegetable oils, and fish are sources of unsaturated fats." Which is (generally) consistent with what I've read on the topic.
i'm not sure if you're being serious but it'll take longer than 20 miutes, more like 6 hours. this isn't a simple topic but the new science on it is compelling.
Saturated fat is benign. You can eat about as much coconut oil as you care to and the only concern would be excess calories.
