We are writing to ask if you will join us in signing a letter in defense of the science and Professor Tim Noakes of South Africa.

Many of you probably know the story of Professor Noakes. He is a world-famous professor (now emeritus) of Exercise Science and Sports Medicine at the University of Cape Town, who happened to discover that the low-carb diet was highly effective for the treatment of obesity, Type 2 diabetes, and other nutrition-related disease. He became famous in South Africa for promoting the diet—and this led to various forms of retaliation by his colleagues. Perhaps most stunning, however, has been that medical authorities (HPCSA) have subjected Professor Noakes over the past few years to a public hearing, with his medical license hanging in the balance. The charge? Sending a tweet to a breastfeeding mother that she could safely wean her child onto a “LCHF” diet. Specifically he was charged with giving “unconventional advice” that is “not evidence-based."

Prof. Noakes was actually acquitted last April, but the medical board is appealing its own decision. Although there are many disturbing ethical issues surrounding the HPCSA's treatment of Prof. Noakes, this petition will only focus on the fact that his advice IS evidence based and that this evidence is acknowledged by a group of physicians, other health care providers, scientists, and researchers.

To HPCSA:

We understand that you are appealing the April 2017 acquittal of Professor Tim Noakes. Of the various charges alleged against him was the contention that his “unconventional advice” via a tweet to a breastfeeding mother was “not evidence-based.”[1] The judgement on this point by the HPCSA was that Professor Noakes’ tweet was “not not evidence-based,”[2] or, in other words, that it was evidence-based.

We, the undersigned, set forth in this letter a large body of scientific evidence to demonstrate that the kind of diet favored by Professor Noakes—that is, one lower in carbohydrates and higher in fat than the traditional “low-fat” diet--is, indeed, evidence-based.

Low-carbohydrate diets have now been tested in more than 70 clinical trials[3] on nearly 7,000 people, including a wide variety of sick and well populations. Thirty-two of these studies have lasted at least six months and six trials went on for two years, enough time to demonstrate the lack of any negative side effects. In virtually every case, the lower-carb, higher-fat diets did as well or better than competing diets.[4] The cumulative evidence shows that low-carb diets are safe and effective for combating obesity,[5] highly promising for the treatment of Type 2 diabetes,[6] and improve most cardiovascular risk factors.[7]

Moreover, the best-available data from the U.S. government shows that in 1965, Americans ate 39% of calories as carbohydrates and 41% as fat. [8] These percentages are what nutrition researchers now consider to be within the realm of a “low-carbohydrate, high-fat” diet. Thus, all Americans, including infants (the population addressed by Professor Noakes’ tweet) were formerly on the sort of diet that he favors. (This was, of course, before the epidemics of obesity and diabetes from which so many nations suffer today.)

Part of the claim against Professor Noakes was that his tweet responded to a question about weaning an infant child. We understand that the South African pediatric guidelines (2013) advise "From 6 months of age give your baby meat, chicken, fish, or egg every day as often as possible. Give your baby dark green leafy vegetables and orange coloured vegetables and fruit every day.”[9] This advice is entirely consistent with a low-carbohydrate, higher fat diet.

Finally, recent results, published in The Lancet, from the largest-ever and only truly global epidemiological study, called PURE, find that populations with the highest-fat and lowest carbohydrate consumption had the lowest rates of total mortality.[10]

Taken together, these findings firmly support the advice given by Professor Noakes. Further, virtually no rigorous clinical trial data exist to contradict this body of evidence.

Thus, from a scientific perspective, the evidence overwhelmingly supports the idea that a diet low in carbohydrates and high in fat is “evidence based.”
