Well with both its not really a high fat diet but an Optimal Fat diet. Not shorting onesself. It is the LOW fat Dogma of recent past that makes a good balanced diet seem to be high fat to many people.
Yes fats are important to women just as much as men. Not only for T and E but EVERY hormone, as well as a plethora of other body functions. Eating healthy fats can/may actually make you leaner even with a higher intake. Not to mention the good skin and hair, optimal immune funtion, keeping cholestorol in check, Yes by eating fat.
shoot for between .4 and .6g perlb of balanced good (non-trans) fat including all and not ignoring any of the Sats, PUFA's, or MUFA's
Hope that helps,
