Dr. Tim Noakes, a well-respected scientist, researcher, physician and professor at the Division of Exercise Science and Sports Medicine at the University of Cape Town, South Africa, is one of the world’s foremost experts on low-carb diets. In fact, he was instrumental in getting the low-carb diet revolution off the ground.

He’s also an accomplished athlete. As a long-distance endurance runner with 70 marathons under his belt, he had long promoted high-carb diets, himself consuming 400 grams of carbs a day or more when preparing for a race.

Eventually, he discovered this wasn’t the best way to improve athletic endurance and health, and ended up writing a number of popular books on low-carb diets.

From High to Low Carb

Noakes graduated from medical school in 1974. At the time, he was also running, and this was when the high carbohydrate diet really started to become popularized.

Following the advice of one of his professors at the cardiology unit where he worked, he changed to a high-carb diet and began promoting it in his writings, including the book, “Lore of Running,” which was widely read.

“There it says that you must eat lots of carbohydrates for both health and performance. I continued to do this for 33 years until 2010,” Noakes says.

One day in 2010, he went for a run and had one of the worst runs of his life. He also admitted he was overweight, which didn’t help. By chance, that same day he received an advertisement for Dr. Eric C. Westman’s book, “The New Atkins for a New You: The Ultimate Diet for Shedding Weight and Feeling Great.”

It claimed you could lose 6 kilos (13 pounds) in six weeks, which he didn’t believe because he’d tried many diets and none worked. Despite that, he bought the book, and within two hours of reading, he realized he’d had it all wrong all this time.

“I decided then and there that I was going to go low-carb. I started at lunchtime on that day. I’ve been on that diet now for the last six years. I’ve dropped 20 kilograms (44 pounds) in weight. My running returned to what it had been 20 years earlier,” he says.

“I subsequently discovered that I have type 2 diabetes because of a strong family history and all these carbohydrates. But I’m glad to say today all my blood tests are within the normal range. I am taking medication. But … in six years with diagnosed diabetes, I have not worsened.

In fact, I’m probably slightly better than I was six years ago, which is completely contrary to what would happen if you followed conventional advice. Anyway, I decided that I’d start reading. I read all your work. I read all the books. I started doing research.

That convinced me that this is a really important change that we need to promote throughout the world. Clearly, the diabetes and obesity epidemics started in 1977. It’s caused by the dietary guidelines. I slowly began to understand [how] industry has driven the bad guidelines …

I also do intermittent fasting. I only eat between lunchtime and … 8 p.m. … I found that that’s been really helpful. It’s about a 16-hour fast and an eight-hour period where I eat.”
