Kessler published a book entitled A Question of Intent, which gave his view of his time at the FDA, focusing on his attempts to change tobacco legislation and the interpretation of that legislation, and his battle with the then-illegal, but still used Y1 strain of tobacco. Kessler also oversaw the FDA-directed moratorium on silicone breast implant devices in 1992. This moratorium led to a deluge of lawsuits in the following months, many of which were filed prior to the federal judiciary's adoption of the Daubert standard for expert testimony in 1993. These lawsuits ultimately led to perhaps the largest settlement in the history of medical devices, Dow Corning's declaration of bankruptcy, and ongoing payments to individuals for conditions that have nothing to do with silicone. Scientific panels funded by three different government agencies conducted comprehensive assessments and later arrived independently at the same conclusion: that there was no connection between silicone gel implants and systemic disease.

He was awarded the Public Welfare Medal from the National Academy of Sciences in 2001. In 2003 he was recruited to a post as dean and vice-chancellor at the University of California, San Francisco Medical School. After his arrival at UCSF, Kessler uncovered multiple spreadsheets for the same closed fiscal year (a year prior to his recruitment), all showing different revenue and expense numbers, but indicating that the dean's office was in deficit and would continue to be so, in direct contravention of what had been reported to him during his recruitment, evidence of, at best, inadequate financial controls. J. Michael Bishop, Chancellor of UCSF, stated UC audits found no evidence of financial irregularities and, in June 2007, Bishop demanded Kessler's resignation. On December 13, 2007, Kessler was formally dismissed. Bishop then acknowledged that the financial data presented to Kessler during his recruitment might have been misleading. Kessler alleged he was fired for whistleblowing. Subsequent to Kessler's firing, after UCSF was pressured by KPMG to release one of the audits, it was revealed that Kessler had been correct. His 2009 book entitled The End of Overeating (a New York Times best seller), highlights for the consumer the amount of fat, salt, and sugar in their food intake.
