The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible (2007) chronicles his experiment to live for one year according to all the moral codes expressed in the Bible, including stoning adulterers, blowing a shofar at the beginning of every month, and refraining from trimming the corners of his facial hair (which he followed by not trimming his facial hair at all). The book spent 11 weeks on the New York Times bestseller list, and Jacobs gave a TED talk about what he learned during the project. In May 2017, CBS Television picked up a TV series based on the book. It was originally renamed By the Book for television, but later changed to Living Biblically. The Guinea Pig Diaries: My Life as an Experiment (2009) is a series of first person essays about his experiences with various guides for human behavior, including thanking everyone for the morning cup of coffee. Jacobs is the author of The Two Kings: Elvis and Jesus (1994), an irreverent comedic comparison of Elvis Presley and Jesus; and America Off-Line (1996). He also writes for mental floss, a trivia magazine. In his book Drop Dead Healthy: One Man's Humble Quest for Bodily Perfection (2012), he explores different ways humans can bring their bodies to peak health, from diet to exercise. He wrote the book while walking on a treadmill. Jacobs gave a related TED talk about this health quest entitled "How Healthy Living Nearly Killed Me". From 2011 to 2012, Jacobs wrote the "Extreme Health" column for Esquire magazine, covering such topics as high-intensity interval training and the quantified self. Since 2012, he has written the "Modern Problems" advice column for mental floss magazine. The column compares modern day life to the horrors of the past. As of May 2013, Jacobs writes a weekly advice column for Esquire.com called "My Huddled Masses". The column is crowdsourced to Jacobs's 100,000 Facebook followers, who give etiquette and love advice. He also writes the regular feature "Obituaries" for Esquire, which consists of satirical death notices for cultural trends, such as American hegemony. As of 2015 Jacobs was working on a project called the Global Family Reunion, where he aims to connect as many people as possible to the global family tree at Geni.com and WikiTree. He hosted the Global Family Reunion, planned to be largest family reunion in history on June
