Calling All Ray Peat Fans!

Just wondering what your sources are that say all PUFAs decrease metabolic rate?

Would you mind linking some studies that demonstrate this?

Cool thanks.

It's not a thought experiment.

I'd wager the corn oil fed pigs would be less healthy, but who knows. Not sure how this thought experiment is applicable to this question though.

If you look at short term studies in humans there are various different results, but frequently O6's seem to increase metabolic rate (according to people like Masterjohn and I believe Jaminet, this is due to their toxicity): http://link.springer.com/article/10.1007%2FBF01617803 However, in longer studies this effect may disappear or even be slightly reversed: http://www.jacn.org/content/21/3/275.full But again, the evidence is pretty weak, so I'm hesitant to make any solid conclusions.

I am a fan of Ray Peat (or rather many of his dietary principles), but omega-3's do not seem to decrease metabolic rate, I have looked. Here are two studies I found, in both resting metabolic rate did not decrease with fish oil consumption:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2958879/

http://www.ncbi.nlm.nih.gov/pubmed/15481762

(edit) And another:

http://www.ncbi.nlm.nih.gov/pubmed/19480700

I don't know about omega-6's lowering metabolic rate. I've seen mixed things, but I'm doubtful that they do.

If PUFA has an effect on metabolism, and I sort of doubt it, it wouldn't be at the level of the mitochondria nor the Thyroid. I can see an argument for excessive quantities leading to liver pathology, especially in the presence of a diet rich in fructose.

I do not believe that in the context of whole food, whether who fruit or oily fish, either is an issue.

I think Peat is correct that PUFA isn't our friend but only when we are talking about refined foods.

Just get your n-3s from whole source, fresh. Fish roe is the best source, better even than the fish meat. It has even less omega 6s, and its also loaded with Vitamin E and C to keep oxidising at bay.

Take a bunch of pigs, feed one coconut oil, or butter, and feed the others corn oil, high pufa oils, etc. See what happens.
