Books and media commentary

Downplaying pandemic infectious disease

Swine flu, SARS, and avian influenza outbreaks

In his books, columns, and interviews, Siegel criticized public health officials and the press for what he considered to be overreactions to, or excessive focus on, infectious disease outbreaks, such as the swine flu, SARS, and avian influenza outbreaks, arguing that resources should be directed toward other health threats.[5][6] He has written three books promoting this view: False Alarm: the Truth About the Epidemic of Fear (2005),[7] Bird Flu: Everything You Need to Know About the Next Pandemic (2006),[5] and Swine Flu: The New Pandemic (2009).[8] Siegel promoted his book False Alarm in a September 2005 appearance on The Daily Show with Jon Stewart.[9]

In 2001, Siegel recommended that individuals focus their health efforts based on the most likely ailments, rather than those that generate the most media. At the time, bovine spongiform encephalopathy (“mad cow disease”) was generating headlines, but the average American woman faced a 1-in-3 lifetime chance of heart disease, a much higher risk. Siegel suggested focusing on everyday interventions that can produce large health impacts, rather than media-driven fears.[10]

During the 2009 outbreak of Swine flu, Siegel was a proponent of administering Tamiflu to children at summer camps "where there have been large, confirmed outbreaks"; Siegel said that he respectfully disagreed with the CDC's guidance to limit the use of Tamiflu in camps to conserve limited stockpiles of the drug and prevent the emergence of drug-resistant influenza strains.[11]

COVID-19 pandemic

During the COVID-19 pandemic in the United States, Siegel frequently appeared in media where he at time questioned the changing CDC guidelines and at times supported them.[12] In a March 2020 appearance on Fox News's Hannity, Siegel stated that, based on the declining case count in China at the time, COVID-19 "should be compared to the flu."[13][14][15] A study by Kathleen Hall Jamieson and Dolores Albarracín, published in the peer-reviewed Harvard Kennedy School Misinformation Review in April 2020, identified Siegel's statement as part of a broader set of COVID-19 misinformation circulating in conservative media; the study found that Americans who relied upon Fox News and other right-wing sources for news were more likely to credit conspiracy theories or baseless rumors than Americans who relied upon mainstream sources.[14][16]

Siegel at times praised President Donald Trump's handling of the coronavirus pandemic.[12] In July 2020, Siegel interviewed Trump on Fox News about the results of his recent cognitive assessment. During the interview, Trump described the test's contents using the phrase "person, woman, man, camera, TV"; Trump's remark went viral and was widely parodied.[17][18]

In July 2021, Siegel interviewed Dr. Fauci on SiriusXM's Doctor Radio, during which Dr. Fauci noted that masking may be required into 2022 to protect the vulnerable.[19] In a 2022 interview with Siegel, Dr. Fauci discussed future boosters.[20][21] In July 2021, Siegel urged TV viewers to get vaccinated, noting in a TV appearance that "the vaccine works extremely well even against the delta variant, preventing infection in 90 percent of cases."[22] In August 2021, Siegel advocated for wider availability of booster shots as a means to provide enhanced protection to broader groups.[23]

Affordable Care Act

Siegel criticized President Barack Obama over portions of his Patient Protection and Affordable Care Act (ACA), a health care reform legislation.[24] In 2017, Siegel wrote an op-ed in the New York Times that criticized the ACA and its essential health benefits provision (which he described as "an overstuffed prix fixe meal filled with benefits like maternity and mental health coverage") and praised the Republican legislation to repeal the ACA.[25] During the repeal debate, Siegel supported Republican legislation that would limit "the menu of essential benefits" and instead create subsidized "high-risk pools" for uninsured patients with pre-existing conditions, although he also opposed "drastic cuts to Medicaid."[25]

In 2018, Siegel published an opinion piece in support of the Affordable Care Act's requirement that restaurants make calorie information available to diners, noting studies that suggest calorie labeling can reduce intake by 30-40 calories daily, which adds up to a weight change of 3 to 5 pounds per year.[26]

Presidential candidate health

During the Trump administration, Siegel interviewed then-President Trump about topics including his health, during which Trump described a cognitive evaluation as requiring him to remember "person, woman, man, camera, TV." The phrase later became a meme. The interview was described as prompting a "six-minute meander through Trump’s thicket of self-diagnosis, during which the president mentioned China, Russia, Ukraine, judicial appointments, the Twenty-fifth Amendment, and, most notably, his ability to recite a string of five words while under observation by medical experts."[27]

Siegel reviewed the medical records of Senator John McCain during his 2000 presidential campaign, among others.[28] In September 2016, Siegel urged then-candidates Hilary Clinton and Donald Trump to release their health records, noting Trump’s weight and diet created risks regarding his ability to serve.[29] In Fox News appearances during the 2016 U.S. presidential campaign, he urged the release of health records of candidate Hillary Clinton, in order to evaluate her physical fitness for office.[30][31][32] In a USA Today opinion piece published April 2015, Siegel compared the public release of Senator John McCain’s health records during his presidential campaign to Secretary Clinton’s refusal to release hers.[33]

Paranormal perception and healing

The mind-body problem refers to the challenge of reconciling neuro-physiology and consciousness in the human mind and brain. In The Inner Pulse: Unlocking the Secret Code of Sickness and Health (2011),[34] Siegel posits perceptible but ineffable and immeasurable "essential life force" "where the physical and the spiritual combine," advising readers to engage in practices to strengthen and focus it for use in overcoming disease and healing. It was reviewed in Publishers Weekly as "an intriguing approach to the mind/body conundrum.".[35]

Host of Doctor Radio Reports on SiriusXM

Siegel has hosted the SiriusXM radio show Doctor Radio Reports [36] twice a week since March 2020, focusing on the impact of the COVID-19 pandemic and the efficacy of public health efforts to neutralize it.

Personal life

Siegel was born on June 15, 1956, in New York. He is married to Ludmilla Luda Siegel, who is a physician and neurologist. They have 3 children.

Siegel is Jewish and cites the Oath of Maimonides as a medical ethics influence.[24]


He attended East Meadow High School. Following high school, he went to Brown University in Providence, Rhode Island from 1974 to 1978. He received his Doctor of Medicine degree in 1985 from the State University of New York at Buffalo. He completed his residency in Internal Medicine in 1988 at New York University Medical Center.[37]
