My opinion won't amount to much, but you should hear all opinions. Fat intake has nothing to do with weight gain. That theory is long gone. The Akins diet should have proved that to everyone.
I have horses and when I want to fatten them up, I give them bread (worthless carbs, little fat) when the horses are racing and I want to slim them down, I give them Fat. It's the same with humans. Just my humble opinion that has helped me loose weight. And fyi, I lose weight everytime I do a flush.
