All the craze against fats applies mostly to cooked fats. Cooked fats (containing trans-fatty acids) are totally destructive to sound health.
Eating fresh coconut flesh, avocados, olives and durian can help a person lose weight because these fats contain lipase enzymes which allow body fat to be burned.
Raw plant fats (in reasonable quantities) are easily recognized by the liver and distributed properly throughout the body.
Raw plant fats have exactly the opposite effect of cooked fats. Raw plant fats are incredible: they are antioxidants, they insulate the nerves, they protect us from pollution, they moisturize the skin, and they ease digestion by lubricating the delicate mucus lining. I have strong experiential evidence that a high raw-fat diet is the best approach for some, but certainly not all.
Fats are the bridge which carry one from a cooked-food diet to raw-food nutrition. Fats fill that empty space perfectly. They are what the body requires to function optimally. They satiate hunger.
