Arne Vernon Astrup (born August 1, in Frederiksberg, 1955) is a Danish nutritionist, chief physician, researcher, author and professor. He is known as a researcher, communicator and author and has published more than 900 scientific articles.^[1] In 2018 he was internationally recognised as one of the world's most cited researchers.^[2] Arne Astrup has contributed to the identification of GLP-1 as a satiety hormone,^[3] which has played a key role in the development of GLP-1 drugs for the treatment of obesity,^[4] which has contributed to the success of Novo Nordisk A/S and their drug Wegovy.^[5]

From 1990 to 2020 was head of the Department of Nutrition, Exercise and Sports at the Faculty of Science at the University of Copenhagen. In the fall of 2016, the department was ranked by the internationally recognised Shanghai Ranking as the world's leading research environment in its field.^[6]

Astrup completed his medical studies at the University of Copenhagen in 1981. In 1986, he received his medical doctorate (Dr. med.) for his dissertation on metabolism in humans.^[7] Subsequently, he continued his training as a specialist in Internal Medicine. He was at the final stage of his specialist training when he became head of the Danish Royal Veterinary and Agricultural University in 1990. He was made a Knight of the Order of Dannebrog in 1999 by Her Majesty Queen Margrethe II of Denmark, and Knight 1st Class of the Order of Dannebrog in 2012.^[8]

Since July 1, 2020, Arne Astrup has taken on the role of Senior Vice President, Obesity and Nutritional Sciences, at the Novo Nordisk Foundation.^[2]

Arne Astrup has achieved national and international recognition since the 1990s. He is known for being one of the most cited researchers in the world. His work in the intersection between industry and academia has resulted in several controversies^[9] that have made his name publicly known in the wider Danish population.^[10]

• Public attention: In the 1990s, Arne Astrup gained public attention due to his new methods for measuring appetite and energy intake.
• Chairman of the National Nutrition Council: From 1993 to 2001, he was the chairman of the National Nutrition Council (replaced by the Council for Physical Activity and Nutrition in 2005) and contributed to the ban on industrially produced trans fats in Denmark in 2004.^[8]
• Academically active for 30 years: During an academic career spanning 30 years, Arne Astrup has primarily focused on research in appetite regulation, treatment of obesity, type 2 diabetes, cardiovascular diseases, and other conditions where nutrition and physical activity are significant.
• GLP-1 as a satiety hormone: In 1996, together with Jens Juul Holst, he identified GLP-1 as a satiety hormone, leading to a patent that helped Novo Nordisk A/S develop GLP-1 analogs for severe obesity.^[8]
• World Obesity Federation: Astrup was president of the World Obesity Federation for four years (formerly The International Association for the Study of Obesity (IASO)).^[8][2]
• OPUS Centre: Director of the OPUS Centre ("New Nordic Everyday Food") supported by the Nordea Foundation with DKK 100 million (2009–2014).

• 900+ scientific articles: He has published more than 900 peer-reviewed scientific articles and over 1000 other academic texts, including abstracts, textbook chapters, and scientific letters.^[4][5]
• Among the world's most cited: Arne Astrup is internationally recognised as one of the world's most cited researchers.^[8]
• Knight of the Order of the Dannebrog: Knight of the Order of the Dannebrog in 1999, and Knight 1st Class of the Order of the Dannebrog in 2012.

Arne Astrup has a background in nutrition research, where he has worked with both experimental physiological and biochemical research as well as clinical treatment trials with subjects and patients. His scientific work has contributed to the understanding of human appetite regulation and energy metabolism, which has led to insights into adipose tissue deposition and body weight.^[11][5]

In collaboration with Professor Jens Juul Holst, he discovered that GLP-1 acts as a satiety hormone in humans.^[3][5] This discovery has played a key role in the development of GLP-1 drugs for the treatment of obesity, which has contributed to the success of Novo Nordisk A/S and their drug Wegovy.

Arne Astrup has published numerous scientific articles in recognized international journals such as The Lancet, British Medical Journal, Nature^[8] and New England Journal of Medicine. In 2018, he was included in the Web of Science list of the world's most cited scientists.^[7]

Throughout his career, Astrup has also been a dedicated supervisor for 42 PhD students^[5] and has contributed to research through an interdisciplinary perspective since his student days.

Despite being a department head for decades and hence not expected to be actively researching, Arne Astrup has published more than 900 scientific publications, as well as a number of scientific and popular science books throughout his career. As a result, in 2010 he was ranked number 5 in the international ranking of the world's most productive researchers in the field of overweight and obesity by ISIS Reuters. He is also a frequent contributor to leading medical journals such as The Lancet, New England Journal of Medicine and American Journal of Clinical Nutrition. Professionally, he is a trendsetter, which is why in 2018 he was included in Clarivate's exclusive list of the most cited researchers in the world.^[5][7] A list that only 32 other researchers at the University of Copenhagen have made. He has also written columns and letters to the editor in Ekstra Bladet, 24 Timer and Ude og Hjemme, among others. He has received numerous honors for his research and was appointed Knight of Dannebrog in 1991 and Knight of the Order of Dannebrog 1st degree in 2012.

Through his work as head of the Department of Human Nutrition (and since 2012 the Department of Nutrition, Exercise and Sports), Arne Astrup has had a significant influence on the development of the field of nutrition, including being the initiator of establishing the Master's programs in Human Nutrition, as well as Clinical Nutrition at the Danish Royal Veterinary and Agricultural University (since 2007 part of the University of Copenhagen).

Arne Astrup is behind the EU diet project “Diogenes”,^[12] supported by the EU Framework Program with 15 million euros, which showed that a diet with more protein and fewer carbohydrates could promote weight control in overweight people after weight loss. Together with Master of Science in Human Nutrition Christian Bitz, he has disseminated the principles of Diogenes in the book “The World's Best Diet”, which has sold over 100,000 copies and has been translated into 4 languages.

Astrup has faced criticism for combining his research responsibilities with personal economic interests on several occasions. For instance, he held a dual role with the company Neurosearch, acting as an advisor and owning stocks while publicly endorsing the company’s diet pill in his column, "Doktor Slank" ("Doctor Skinny").^[13] This raised concerns about potential conflicts of interest. Following the negative publicity, Astrup sold his shares in Neurosearch, which were valued at approximately DKK 200,000.^[13] He maintains that he was able to keep his professional and personal interests separate.

Arne Astrup has received a number of Danish and international awards throughout his career, including:

Arne Astrup has published several books together with other authors such as Claus Meyer, Christian Bitz, Mads Fiil Hjorth and others.^[21]
