[1] Campos worked at the law firm Latham & Watkins in Chicago from 1989-1990 and became an associate professor at the University of Colorado in 1990, where he teaches classes on property, punishment theory, jurisprudence and legal interpretation.
[4][5][6][7] Soowon Kim and Barry M. Popkin praised Campos for "bringing attention to some of the complexities in overweight/obesity and health relationships and covert financial interests involved in obesity research" but criticized him for "selective use of research", "fallacious interpretation of literature" and "misunderstanding of basic epidemiological principles" and thereby "harm[ing] the most vulnerable subgroups in the population.
"[4] Neville Rigby criticized Campos's lack of relevant academic qualifications and poor grasp of scientific research, noting that: "It is unusual to find academics concerned chiefly with legal, social, political, and educational issues seeking to challenge the whole arena of the epidemiology, clinical, and public health aspects of the obesity problem.
"[5] June Stevens, Jill E. McClain and Kimberly P. Truesdale countered specific claims about the state of scientific research made by Campos.
[8] Campos's obesity work was praised by sociologist Susie Orbach for discussing unhealthy body image issues related to an emphasis on extreme thinness.
Most crucial of all, they have each contributed to building the case against seeing obesity per se as a disease, demonstrating that the health risks of fatness are, at the very least, highly debatable ... More recently, Campos has been a tireless, acerbic, and superbly articulate warrior in his extensive print and electronic media work."
