Professor Louise Burke is a sports dietician with nearly 30 years of experience in the counselling and education of elite athletes. Since 1990 she has served as the head of sports nutrition at the Australian Institute of Sport and served as the team dietician for the Australian Olympic team for five Summer Olympics from 1996-2012. Burke is also director of the International Olympic Committee diploma in sports nutrition and is part of the Nutrition Working Group of the IOC. Her research and education interests in sports supplements have included work on caffeine and sports performance. Louise has a very modest caffeine habit. She hates coffee and has never tried an energy drink, and her daily caffeine intake consists (to her husband's annoyance) of half-cups of weak black tea. She is committed to practicing her (also very modest) sporting ability. Towards the end of her annual marathon she consumes caffeinated cola drinks or sports confectionary, which gets her to the finish line with a smile on her face.
