Having previously shown you what I look like on a lowish-carbohydrate diet, here are a couple of recent pictures of Jimmy Moore, who's on a very-low-carb, very-high-fat diet (~85%E from fats), a.k.a. Nutritional Ketosis. It involves adding Kerrygold butter to just about everything, even eating sticks of it from a block. I'm not kidding.
|I told you I wasn't kidding.|
From Google Image Search on "Jimmy Moore" OR "Livin la Vida low carb", images in the last 7 days:-
The only recent footage of Fredrick Hahn, is the following video from the Low Carb Cruise...
To my eyes, Nutritional Ketosis is good for absolutely nothing. Dietary fat can be stored as body fat, in the absence of dietary carbohydrates. Gary Taubes' claim "You can basically exercise as much gluttony as you want, as long as you're eating (only) fat and protein." is pure fantasy, not supported by evidence.
The low protein intake in Nutritional Ketosis, combined with the high serum cortisol that's almost inevitable on this way of eating, results in a loss of muscle mass. I give Nutritional Ketosis a thumbs-down.
1) No Energy Deficit → No Weight Loss. There is no Metabolic Advantage to Nutritional Ketosis. See http://www.jbc.org/content/92/3/679.full.pdf
2) Insufficient carbohydrate intake and insufficient protein intake starves the liver & kidneys of gluconeogenic pre-cursors, which raises cortisol, which converts muscle mass into gluconeogenic pre-cursors e.g. Glutamine, Alanine etc. This is standard Biochemistry. No links required.
3) While excess carbohydrates are converted into triglycerides by the liver, excess fats are converted into cholesterol by the liver, which is exported to tissues as LDL-C.
LDL-P ∝ LDL-C. High LDL-P is strongly associated with increased risk factor for CHD. See http://www.lecturepad.org/dayspring/lipidaholics/pdf/LipidaholicsCase291.pdf
CHD is not an inflammation-mediated phenomenon. It's an LDL-P and neovascularisation-mediated phenomenon. See http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3492120/
4) Read Page 10 of https://www.drmcdougall.com/misc/2013nl/feb/pritikinpdf3.pdf, starting from "Could such a cream meal precipitate an angina attack because the oxygen-carrying capacity of the blood is lowered?" It's an actual trial on humans with clogged coronary arteries. It's not a hypothesis.
5) Chronically-raised cortisol causes aggressive behaviour (cortisol is a stress hormone) and adversely affects short-term memory storage in the Hippocampus. See http://evolutionarypsychiatry.blogspot.co.uk/search?q=cortisol
6) Eskimos, Sami, Masai, Samburu, Tokelauans etc, get ~50% of their total energy from fats. There are zero populations that get ≥80%E from fats.
Update 25th July 2014: I appear to have rustled Fredrick Hahn's Jimmies. See https://www.facebook.com/FredrickHahn/posts/10152227780827864
I can safely state that Fredrick Hahn is a liar (I am not poking fun at anybody and I have only blocked him (not his followers) from posting here, for a flagrant breach of my Moderation Policy on his first attempt at commenting), and intellectually-dishonest (for repeatedly mis-quoting me, and using other logical fallacies). He posted the above post knowing that, as I had blocked him on Facebook, I wouldn't see it. I only learned of its existence after a friend PM'ed me on Facebook Messenger. He instructed his "followers" to leave comments here and then accuse me of lying about white-listing, back on his page, because their comments didn't appear immediately. He's a real piece of work! From ABOUT ME:-
Moderation Policy: Comments from first-time & untrusted commenters are moderated ← (click for details). Please be patient. Now that I have a Smart Phone, I can publish your comments during the day when I'm away from my lap-top, but I prefer to type replies on my lap-top. Comments from anonymous commenters, containing links in any form, are deleted.
This is a function of Disqus, as it's impossible to retrospectively white-list a commenter who's never commented here before. There appears to be a severe lack of cognitive function in these people. I really can't think why that is ;-)
Why am I being so hard on Jimmy Moore and Fredrick Hahn? I don't know these people personally.
1) These people are making money out of peddling pseudoscience.
2) These people meet all the criteria in Guest post: Science versus Pseudoscience and have created an alternative science, where sky-high LDL cholesterol, sky-high LDL-P and sky-high postprandial TG's are not risk factors for CHD, but are either harmless or beneficial.
