My family I lead and lived healthy life stile for almost 53 years. All food was home made from scratch using best ingredients possible and care was taken to enjoy very balanced diet with strict avoidance of bad and unhealthy fats and meats like red meet etc. Alcohol was never touched unless is offered to visitors.
And, I had prostate Ca at age of 51 with no family history.
A year plus ago, I decided to turn my diet upside down. I started enjoying steaks, fajitas, pork meat etc. I love my steak charred a bit at fatty side in combination with chilled glass of red wine ( merlot or Malbec).
And guess what: no change in my cholesterol levels, BP stayed stable and same, I did not gain weight.
I can’t even imagine how much of life I missed.
Now, my motto is: Eat and enjoy, life is too short.

It is however a recommendation for me, or at least I have the same approach, more or less.
So many of us used to eat margarine as we tried to stay away from the so called evils of saturated fat, trying to follow advice we thought was good. As well as trying to keep the fat low in other ways, which usually meant keeping the carbs higher. That was the advice for decades, starting I suppose when
Ancel Keys got the ear of the US government in the 50s, decades during which diabetes increased by a factor of 8. That was the advice from our government and medical authorities, and I followed it as best I could for a long time.
I never saw any apologies about
the margarine/trans fat screw up, they just quietly stopped recommending that. (How long was that the advice? Years? Decades?) How long has it been since you guys have seen any recommendations for partially hydrogenated vegetable oil(AKA trans fats) colored to look like butter? And, judging by the OP and some other studies, and what some of my diabetic friends are telling me about
their treatment at one clinic, maybe they are slowly coming around about
some of their other advice.
It is a long battle, and there are so few scientific studies to really determine if some one's theories on eating are correct, even though they so often sound logical. Obviously eating saturated fat is, among other problems, going to clog up your arteries, right? ( WARNING: long quotes from article on Ancel Keys follows)

Ancel Benjamin Keys (January 26, 1904 – November 20, 2004) was an American physiologist who studied the influence of diet on health. In particular, he hypothesized that dietary saturated fat causes cardiovascular heart disease and should be avoided. Modern dietary recommendations by health organizations, systematic reviews, and national health agencies............
Keys studied starvation in men and published The Biology of Human Starvation (1950), which remains the only source of its kind. He examined the epidemiology of cardiovascular disease (CVD) and was responsible for two famous diets: K-rations, formulated as balanced meals for combat soldiers in World War II, and the Mediterranean diet, which he popularized with his wife Margaret. Science, diet, and health were central themes in his professional and private lives. ......................................................................His interest in diet and cardiovascular disease (CVD) was prompted, in part, by seemingly counter-intuitive data: American business executives, presumably among the best-fed persons, had high rates of heart disease, while in post-war Europe CVD rates had decreased sharply in the wake of reduced food supplies. Keys postulated a correlation between cholesterol levels and CVD and initiated a study of Minnesota businessmen (the first prospective study of CVD).[35] At a 1955 expert meeting at the World Health Organization in Geneva, Keys presented his diet-lipid-heart disease hypothesis with "his usual confidence and bluntness".[36][37] Naples was the first case study that seemed to support his hypothesis.[38]
After observing in southern Italy the highest concentration of centenarians in the world, Keys hypothesized that a Mediterranean-style diet low in animal fat protected against heart disease and that a diet high in animal fats led to heart disease. The results of what later became known as the Seven Countries Study appeared to show that serum cholesterol was strongly related to coronary heart disease mortality both at the population and at the individual level.[39][40] As a result, in 1956 representatives of the American Heart Association appeared on television to inform people that a diet which included large amounts of butter, lard, eggs, and beef would lead to coronary heart disease. This resulted in the American government recommending that people adopt a low-fat diet in order to prevent heart disease.
Keys had concluded that saturated fats as found in milk and meat have adverse effects, while unsaturated fats found in vegetable oils had beneficial effects. ( My addition: here came frying in vegy oil(trans fats produced) and margarine replacing butter) This message was obscured for a 20-year period starting around 1985, when all dietary fats were considered unhealthy. This was driven largely by the hypothesis that all dietary fats cause obesity and cancer.[41][citation needed] A 2015 systematic review and meta-analysis by the Cochrane Collaboration, an organisation which promotes evidence-based medicine, found that reducing saturated fat intake reduced the risk of cardiovascular disease, concluding: "Lifestyle advice to all those at risk of cardiovascular disease and to lower risk population groups should continue to include permanent reduction of dietary saturated fat and partial replacement by unsaturated fats."
Keys equation
The Keys equation predicts the effect of saturated and polyunsaturated fatty acids in the diet on serum cholesterol levels. Keys found that saturated fats increase total and LDL cholesterol twice as much as polyunsaturated fats lower them.[42]
Change in serum cholesterol concentration
(mmol/l) = 0.031(2Dsf − Dpuf) + 1.5√Dch
where Dsf is the change in percentage of dietary energy from saturated fats, Dpuf is the change in percentage of dietary energy from polyunsaturated fats, and Dch is the change in intake of dietary cholesterol.[43]
The sugar controversy
In 1972, Pure, White and Deadly was published, written by John Yudkin for a lay readership. Its intention was to summarize the evidence that the over-consumption of sugar was leading to a greatly increased incidence of coronary thrombosis, and that in addition it was certainly involved in dental caries, probably involved in obesity, diabetes and liver disease, and possibly involved in gout, dyspepsia and some cancers.
Yudkin ended the first Chapter: "I hope that when you have read this book I shall have convinced you that sugar is really dangerous." This message was extremely unwelcome to the sugar industry and manufacturers of processed foods. The final Chapter of Pure, White and Deadly lists several examples of attempts to interfere with the funding of his research and to prevent its publication. It also refers to the rancorous language and personal smears used by Ancel Keys to dismiss the evidence that sugar was the true culprit.
Keys wrote, for example:
It is clear that Yudkin has no theoretical basis or experimental evidence to support his claim for a major influence of dietary sucrose in the etiology of CHD; his claim that men who have CHD are excessive sugar eaters is nowhere confirmed but is disproved by many studies superior in methodology and/or magnitude to his own; and his "evidence" from population statistics and time trends will not bear up under the most elementary critical examination. But the propaganda keeps on reverberating ... [44] Unfortunately, Yudkin's views appeal to some commercial interests with the result that this discredited propaganda is periodically rebroadcast to the general public of many countries.[45]
The efforts to discredit the case against sugar were largely successful, and by the time of Yudkin's death in 1995 his warnings were, for the most part, no longer being taken seriously.[citation needed]
Yudkin's arguments and evidence for the dangers of sugar were the focus of several articles in the British Medical Journal of 19 January 2013.[46]
In 2009, Robert Lustig, a pediatric endocrinologist of the University of California, San Francisco, Medical School who has a special interest in childhood obesity, made a video called Sugar: The Bitter Truth.[47] Lustig had independently re-discovered and confirmed Yudkin's findings and, taking aim at Keys[citation needed], asked his audience, "Am I debunking?"................
Criticism
Some doctors and nutritionists have been critical of Keys' implications.[60] His famous seven countries study, which led to the medical opinion regarding the dangers of cholesterol, fat and substances containing the same, has been criticized as ignoring the cases of Denmark, France and Norway (countries where the diet is rich in fat, but occurrence of heart disease is low) and Chile (where diet is low in fat, yet occurrence of heart disease is high).[61][62] ............
