In 1928, both Stefansson and Anderson joined in an experiment at Bellevue Hospital in New York. The subject of the experiment was what the effects of an “all-meat” diet would be on the human body. It was supervised by leaders in scientific research on the subject. The purpose of the study would be to answer common concerns about such a diet. Would the lack of vegetables cause scurvy? Would this “all meat diet" cause mineral deficiencies, other deficiency diseases, have harmful effects on the heart, kidneys, blood vessels, or promote harmful bacterial growth in the stomach?
The experiment was one year long. In 1930 the results were published in "The Journal of Biological Chemistry". Of course, the results and conclusion was an outstanding negative but the experiment effects were positive ones. Only when there was a restriction in fats did there seem to be any adverse reaction from Stefansson. Additionally, Stefansson saw a drop in his cholesterol which, when ending the study and returning to a “normal” diet began to rise.
Even with this publication and its findings the people of the time still found it impossible to believe that a low carb diet, allowing so much meat and fat, could result in weight loss. It was impossible for them to get past the thought of consuming that many calories and not gaining weight. (1930 or 2005 - we haven't changed much as people, have we?)
In 1933 yet another study was done at the Royal Infirmary in Edinburgh. This study took a look at the effects of high and low calorie diets. Interestingly enough, and noted by the doctorss performing the experiment, in those subjects where carbohydrates were lowered the most, weight loss was greatest!
Likewise in the USA in 1955, the Dr. Albert Pennington report, which eventually was deemed “The Holiday Diet” after being published in Holiday Magazine, concluded the same: 'The recommended diet is a calorically unrestricted one, very low in carbohydrate, high in fat and moderate in protein. Neither fat nor protein is restricted, however.'
Professor Alan Kekwick and Dr. Gaston Pawan reported similar results with obese patients in a trial they performed at the Middlesex Hospital, London. In 1959 Dr John Yudkin, Professor of Nutrition and Dietetics, Queen Elizabeth Hospital, University of London confirmed their results.
In the 1950’s Dr Richard Mackarness ran Britain’s first obesity and food allergy clinic. He had so much success prescribing a low carbohydrate, high fat, moderate protein diet for his obese patients that he wrote the book "Eat Fat and Grow Slim" which was in print for over 20 years.
Through the years it still was not popular or accepted by many to believe that low fat dieting and calorie reduction was not the only answer to obesity. In the 1970’s cardiologist Dr. Robert Atkins was highly criticized and called a “fad diet doctor” when he wrote his first publication “Dr. Atkins New Diet Revolution”.
It took until the early 2000’s before studies were actually performed that persuaded modern day “low fat supporters” to take a closer look at low carb living.
As always, studies confirmed the low carb way of eating does and always has worked - not only for weight loss, but the low carb lifestyle also aids in many, many health related conditions .
