ultimately ruled that the FDA did not have the power to enact and enforce the regulations in question. He was awarded the Public Health Hero award on April 2, 2008, by the UC Berkeley School of Public Health for his work in tobacco regulation. 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

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.

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. He asserts that this trio of elements in restaurant and processed foods conditions us to eat more, in a manner that changes our brain circuitry, and that children may develop a pattern of overeating and obesity that they might retain for life. He stresses that this outcome of lifelong obesity is not genetic, but environmental and avoidable. On November 9, 2020, Kessler was announced as one of the three co-chairs of president-elect
