Timothy David Noakes (born 1949) is an A-rated South African professor of exercise and sports science at the University of Cape Town. He has run more than 70 marathons and ultramarathons, and is the author of several books on exercise and diet. He is known for his support of a high-fat, low-carbohydrate diet, as set out in his book The Real Meal Revolution.
Noakes was born in Salisbury, Southern Rhodesia (today Harare, Zimbabwe) in 1949 and moved to South Africa at the age of five. His father had arrived in what was then Southern Rhodesia in 1946, establishing a successful tobacco exporting company that he sold in 1954. As a young boy his main sporting interest was cricket. Noakes attended Monterey Preparatory School in Constantia, Cape Town, then Diocesan College. He has earned an MBChB (1974), MD (1981), and DSc (Med) (2002).
In 1980 Noakes was tasked to start a sports science course at the University of Cape Town. Noakes went on to head the Medical Research Council-funded Bioenergetics of Exercise Research Unit, which was later changed to the MRC/UCT Research Unit for Exercise Science and Sports Medicine.
In the early 1990s Noakes co-founded the Sports Science Institute of South Africa, with former South African rugby player Morne du Plessis. His unit's physiological research has produced over 370 scientific articles since 1996.
He is a leading researcher on the condition now known as Exercise-associated hyponatremia (EAH). He first recognized this condition in a female runner during the 1984 Comrades Marathon, and published his findings in 1985 in the journal Medicine and Science in Sports and Exercise. Noakes hosted the 1st International Exercise-Associated Hyponatremia Consensus Development Conference in Cape Town in May 2005.
Noakes is also known for renewing and elaborating the idea first proposed by the 1922 Nobel Prize in Physiology or Medicine winner Archibald Hill that a central governor regulates exercise to protect body homeostasis.
In 2005 he undertook a series of pioneering experiments in the Arctic and Antarctic on South African (British-born) swimmer Lewis Gordon Pugh to understand the full range of human capability in extreme cold. He discovered that Pugh had the ability to raise his core body temperature before entering the water in anticipation of the cold and coined the phrase 'anticipatory thermo-genesis' to describe it. In 2007 he was the expedition doctor for Pugh’s one kilometre swim at the Geographic North Pole.
Noakes has written several books detailing his research in sports science and nutrition. A selected bibliography is given below.
- Lore of Running (1986) 
- Running Injuries: How to Prevent and Overcome Them (1990)
- Bob Woolmer's Art and Science of Cricket (2008)
- Waterlogged: The Serious Problem of Overhydration in Endurance Sports (2012)
- The Real Meal Revolution (2014)
The "Noakes diet"
The paleolithic diet, often referred to as the "Tim Noakes Diet" in South Africa, has quickly gained popularity in the country in the 2010s, and has drawn a significant amount of criticism, mostly due to Noakes's claims that high blood cholesterol is not a contributing factor to heart disease.
Noakes is also well known for challenging common and old paradigms in the discipline of exercise physiology. In 1996 he was honored by the American College of Sports Medicine when he was asked to present the J.B. Wolfe Memorial Lecture, the college's keynote address at its annual meeting. In his presentation Ex Africa semper aliquid novi (Out of Africa always something new) Noakes challenged the dogma of the VO2max plateau theory. This work lead eventually to the construction of a complex central governor model of exercise in which the brain is the primary organ that dictates how fast, how long, and how hard humans can exercise. Much of Noakes' work over the past 10 years has provided further support for this model. In 2002 he was awarded a Doctorate in Science (DSc), one of the highest degrees the University of Cape Town can award.
