Gillian McKeith

Gillian McKeith (born 28 September 1959) is a Scottish nutritionist, television presenter, and writer. She is the former host in the UK of Channel 4's You Are What You Eat and Granada Television's Dr Gillian McKeith's Feel Fab Forever, and as of 2010 presents Eat Yourself Sexy on the W Network in Canada. She is the author of several books about nutrition, including You Are What You Eat (2004), and Dr Gillian McKeith's Ultimate Health Plan (2006).

McKeith takes a holistic approach to health, promoting exercise, a pescetarian diet high in fruits and vegetables, grains, beans, nuts, and tofu, and the avoidance of processed and high-calorie foods, sugar and fat, red meat, alcohol, caffeine, white flour, and additives. She recommends detox diets and colonic irrigation, argues that the colour of food is nutritionally significant, and claims that she can diagnose ailments by examining people's tongues and stools.

Her advice has attracted criticism and praise. You Are What You Eat has sold over two million copies, and in 2005 she was awarded a Consumer Education Award by the Soil Association. At the same time, the validity of both her approach and her qualifications, as well as the safety of her recommendations have been questioned by a number of health professionals.
