Dr. Richard Mackarness book exposed the "calorie fallacy" and proposed a non-carbohydrate "Stone Age" diet of protein and fat with no restriction as to the amount eaten. OBESITY IS always fatiguing and always a great strain on the body. It is not due to greed but, as Dr. Mackarness so clearly explains in this book, to a little-understood difficulty in the economy of the body which makes it turn sugars and starches into fat instead of promptly using them to give energy, as do the people who remain normal in weight.
Flour is the root of all evil. Sugar is even worse.
Constant-weight people increase their energy expenditure when they eat more. Fatten-easily people can't do this. Part of the problem is that refined carbohydrates, unlike dietary fat, meat, and eggs, don't stimulate the body to burn more fuel. Eliminating refined carbs can make it possible for fatten-easily people to burn fat.
This is the second edition, written 1974. The first edition was 1958.
Time has only slightly dimmed the extreme value of this book. What was certain then is still certain now as it has been for 140+ years that calories restirictive diets do not ultimately work. What works is a closer understandning of how animals who eat a natural diet are never obese, even when food is plentify, And that understanding that humans too have evolved to cope with certain food can lead to a better designed diet. So that it does not matter how much you eat. What is more important is what you eat and how often. This "stone age diet" points to the importance of eating fat. Fat is an essential substance reuired to make enzymens, hormones, nervous tissue, cell structures. And the best fat is that most like our own; animal fat. The modern human diet rich is carbohydrates, such as sugar, flour and other refined and bloated cultivars rice and potatoes mankind would never have encountered. These are manufactured into pretend food, designed to make you want more. They addict the brain and surpress hunger. The solution to obesity, especailly in those that "easily fatten"is simple. Stop eating carbs, especailly refined carbs. Humans have ZERO dietary requirement for carbs as their bodies are perfectly capable of making all they need from fat and protein. And it makes it is the exact amounts in needs. Eat more fat, which is satiating so you are less likely to overeat. Since Mackarness the science has continued to support his observations: Richard Johnson, Robert Lustig, David Perlmutter. Practioners such as Jason Fung, Prandit Jamnadas, and many others. An science Journalists have tracked the woeful history of a nutritional profession, funded by drug compnaies and food companies are still peddling fake harmful advice. This is such an exciting field. Poor diet caused by excess carbohydrate (insulin resistence) is inextricably linked to obesity, Type2 Diabetes and heart disease, what is remark able is the last line in the book.. "If wrong food can make people fat and ruin their teeth, why should it not, in some suseptible people injure their brains and make them appear mad?"
This is now shockingly prophetic since Alzheimers is now also clearly linked to insulin resiistence caused by a lifetime of poor diet.
A short book encouraging low-carb eating for body-fat loss, published pre-Atkins in England (Brawn! heavens, I only even know about boiled pig's head dishes from the TV show Victorian Farm, but apparently they were still being made in the 50s when the version of the book I read was published.) The plan is Banting + a little fruit, carbier than most strict keto people would do these days.
A smart distinction between people who fatten easily and those who don't, which is certainly what I've seen over a lifetime is so. He didn't know about leptin and gherlin and lipase and so on, but he did know that there was some mechanism that resulted in carbs not only fattening, but shutting off the satiety and fat-burning process in the body, which is entirely accurate, we know, now that a dozen hormones have been identified that drive these processes. Cute old-fashion cartoon illustrations make it pleasantly nostalgic.
Worth hunting down the free PDF of the old version for the interesting detail of Evelyn (Mrs. William/ Vilmahjur) Stefansson's preface.
