you're right to be concerned with the calories if weightloss is a goal. you'll have to see how it goes... i would generally advise people to use fats as a cooking tool, not a meal component. you cook with butter, you don't add on everything because saturated fat is so groovy.
"dean ornish and dr. davis think the palmitic acid our bodies use for fuel while we sleep is poison if we eat it. zero-carbers like charles washington think the oldest fuel in our evolutionary history glucose - used by organisms a billion years ago and without which the brains of modern mammals cannot survive for more than a few minutes is an unnatural toxin if you eat it. both views ignore basic facts of medical physiology and defy evolutionary history." - kurt harris
