For 80 years cholesterol experts said ‘eat less fat’. But where was the evidence?

Depressing. A consensus based on nothing much, still lasted three generations

And it’s not dead yet: Groups like the American Heart Association, UCSF Guidelines, VicHealth, etc are all still advising that people avoid saturated fats, and eat whole grains.

For years, people with the kind of high cholesterol linked to their genes, were told they could lower their cholesterol if they stopped eating things like butter, cream, eggs, cheese, chocolate, and even coconut oil.

A new study looked for evidence to justify that advice and couldn’t find any. They are, of course, not the first – even in the 1950s John Yudkin was already warning people about the dangers of sugar. But the vested interests and fat-police leapt into gear, and thus and verily a million low-fat products filled the shelves, most of them with added sugar.

How many people did this consensus kill?

People with high cholesterol should eliminate carbs, not saturated fat, study suggests

“For the past 80 years, people with familial hypercholesterolemia have been told to lower their cholesterol with a low saturated fat diet,” said lead author David Diamond, professor and heart disease researcher at the University of South Florida. “Our study showed that [...]

Wikipedia deletes The List of Scientists who are Skeptics of the sacred (fake) “Consensus”

The evidence is overwhelming but the names of 85 unconvinced experts threatens the Earth. Shield your eyes, sinner, lest ye faith be tested!

The Religion of Carbonoid-Weather-Control is so fragile, and Wikipedia so captured by philosophical fruit flies, that 35 editors voted down 19 other editors and now The List does not exist. Thus do 35 editors keep safe the minds of Wikipedia babes who might get confused when they see Richard Lindzen and Roy Spencers names and mistake them for actual climate scientists… oh.

Thanks to Dr Roger Higgs:

Electroverse: Wikipedia deletes scientists who disagree…

Here’s the reasoning for the censorship given by one of the Wiki editors:

“The result was delete. This is because I see a consensus here that there is no value in having a list that combines the qualities of a) being a scientist, in the general sense of that word, and b) disagreeing with the scientific consensus on global warming.”


I’d like to thank those 35 Wiki editors for telling the world how weak the consensus is and giving skeptics another excuse to highlight this dangerous list. Go Streisand Effect.

Doomsday poll shrinks 25%: Now just 11,000 MeToo scientists say “panic now”

Who remembers that 15,000 scientists signed some climate declaration in 2017? The same Prof Ripple, and Bioscience probably hope you don’t, because two years later there is the same rehashed, but with only 11,000 signatories. So 4,000 disappeared without a trace. There are however, the same comic indefendable graphs. Call it “extreme graphing” — every line needs to be diagonal. All “pauses” are disappearing. No fallacy remains unbroken.

To stop storms we apparently need to reduce the global population, stop mining “excessive” minerals, eat more veges, and we need to preserve biodiversity, reefs, forests and greenery at whatever it was in 1685 or whenever the sacred preindustrial year of Life On Earth is declared. You know the drill — coal and oil are demon spirits. Exorcise them now! Then rinse, repeat and …hand-wash your undies.

This is panic-science: hold the error bars, hide the adjustments and heap on the hype.

Climate crisis: 11,000 scientists warn of ‘untold suffering’

Damian Carrington, The Guardian

The world’s people face “untold suffering due to the climate crisis” unless there are major transformations to global society, according to a stark warning from more than 11,000 scientists.

Skeptics get 49% more media, and other fairy fantasy stories from Nature Gossip Mag

Skeptics get banned, rejected, blocked and sacked from the mainstream media yet somehow Nature has a paper on Skeptics getting too much media. Believers don’t have to be an expert to control the news agenda, just a Greenpeace activist, or a teenage girl. Skeptics on the other hand, can be Nobel Prize winners, but the BBC won’t even phone them.

Nature, the former science giant, just launched the tenets of science over the event horizon. This paper is Argument from Authority rolled into false equivalence, and powered with cherry-picked errors in both category and in categorization. Nonsense on a rocket. It’s not what science is, and it’s not what journalism should be either. And Nature is supposed to be both. Judith Curry calls it The latest travesty in ‘consensus enforcement’ and the worst paper she has ever seen in a reputable journal.


Both David Evans and I get a mention on what is effectively Nature‘s blacklist. What an honour! No really — there are 386 great names. Even more of an honour is a mention on Judith Curry’s site “blogs she’s learnt something from”. (By some freak, my name comes right after Freeman Dyson and Ivar [...]

So what? 15,000 scientists sign warning but 30,000 scientists are skeptics*

Skeptical scientists outnumber the unskeptical ones

The “News” today: 15,000 scientists have signed some 25 year old repeat failed climate doom prediction. Headlines are everywhere.

So today is also the perfect day to point out that ten years ago 31,487 American Scientists, including 9,029 with PhD’s signed the Global Warming Petition Project warning that there is no convincing scientific evidence that man-made CO2 will cause catastrophic heating, and that agreements like Kyoto (and Paris) are harmful, and hinder science.

Opinion polls are a measure of sociology rather than science, but since skeptics win them, go forth and spread the word and shine a light on media bias, as well as on the large unheralded mass of skeptical scientists across the world.

The Petition Project was better done, done years ago, done twice, and has twice as many names on it.

Don’t miss the opportunity to pop in on the same journalists that think a list of 15,000 scientists doing a ten second internet form is newsworthy, but 30,000 checked and accredited scientists signing and mailing a paper form is not. Let them bask in their hypocrisy. Turn the screws on their cognitive dissonance. Be polite. Enjoy their struggle.

Low Fat consensus was wrong: High carb diets increase death rates

How many people have died prematurely because they swapped their fats for carbohydrates?

More fat meant less death (left). More carbs (right) meant the opposite (at least above 60%). (Click to see the full table of Figure 1 results).

New research published in the Lancet shows that low fat diets could increase your risk of death.

Specifically, those who are in the top fifth of carbohydrate-eaters are also about 28% more likely to die than the fifth eating the lowest amount. This is a correlation (only), but the PURE* study was tracking the thing that matters most — all-cause mortality – and they followed the diets of 135,000 people in 18 countries for 5 – 9 years. Loosely, if people avoided high carbohydrate diets, they were less likely to die.

The graph flattens off below “60% carbs” (that’s a percentage of total calories). However, the mortality numbers keep improving for the highest fat intakes which rather skewers 40 years of headlines. I’m guessing that some people who kept carbs below 60% ate more protein instead, which, judging by the “fat” graph, wasn’t as useful.
