Marcus regularly appears in various media outlets in debates relating to childhood obesity. In particular, he has propagated the introduction of a so-called "sugar changeover tax" [5] in, which would increase the price of unhealthy, sugary products such as confectioneries and soda and in turn subsidise a decrease of the Value Added Tax (VAT) on fresh fruit and vegetables. [6]
Marcus has also argued against the so-called Low Carb High Fat Diet (LCHF) and asserts that a high intake of saturated fat is harmful for the body and may cause cardiovascular disease. [7]
Marcus is son to the painter and sculptor Gert Marcus and the poet Anne-Marie Söderlund. As a child he attended the highly acclaimed Adolf Fredrik's Music School in Stockholm, but after high school chose to pursue a career in medicine. Marcus has dedicated much of his spare time as a basketball coach for youth and adolescents in various basketball clubs in Stockholm.

Obesity in Sweden has been increasingly cited as a major health issue in recent years. Sweden is the 90th fattest country in the world. In 2009, the number of people who are considered overweight or obese had not increased for the first time in 70 years. Claude Marcus, a leading Swedish nutrition expert from the Karolinska Institutet, stated that one solution is to introduce a fat tax. Folksam refused to insure a 5-year-old girl from Orust. The insurance company refused her insurance based on "serious overweight/obesity". A report showed that children whose parents were better educated had a lower chance of becoming overweight.
