This paper from Chris makes a nice counterbalance to the fish oil and hepatic lipidosis posts. Long term the omega 3s have benefits. Avoiding omega 6s and avoiding "food" which comes in a plastic wrap does even more in combination. I love interventions which improve insulin sensitivity. If you're not going to mainline leptin I'd suggest fish might be a good idea (or maybe the oils)... I love stuff which increases insulin sensitivity.
BTW The link in this one is interesting too!
