Dan Jacobs caught the cooking bug in 1987 after his father lost his job and began experimenting in the kitchen. Jacobs would hang out with his dad, and they'd toss ingredients into pots and see what would happen. His first restaurant experience was in 1997, when he took a summer job as a short-order cook at a breakfast place in Fish Creek, WI.
Over the next 15 years, Jacobs honed his skills through increasingly demanding and satisfying positions as well as mentorships with well-known chefs in the Chicago area. In 2011, he and his wife, Kate Riley, moved from Chicago to Milwaukee, where he became the executive chef at a farm-to-table restaurant. He followed that with a two-year stint at Odd Duck, where the constantly changing menu allowed for more creative expression.
Then in 2016, Jacobs and his good friend and fellow chef Dan Van Rite opened DanDan, named for the two owners and a Sichuan noodle dish. The restaurant quickly became known for its inventive take on Chinese dishes with Midwestern influences, such as spicy Sichuan pork dumplings and General Tso cauliflower. Following its success, the owners opened EsterEv, which serves a tasting menu. Both restaurants caught the eye of the producers of Top Chef, who were prepping for season 21, which would take place in Wisconsin.
To get cast, Jacobs had to show significant culinary experience, demonstrate his personality and cooking style, and participate in in-depth interviews with the producers. Once the season started, Jacobs knew it would be a grueling ordeal that would require quick thinking, physical exertion, and steady nerves. For any chef, competing is challenging, but for Jacobs, who was diagnosed in 2016 with Kennedy's disease, or spinal-bulbar muscular atrophy—a rare, inherited muscular disorder that causes progressive weakness with muscle cramps, fatigue, and mobility problems—it was particularly demanding.
Getting a diagnosis
Jacobs was 37 when he first experienced fatigue followed by muscle cramps and twitches during a workout with Kate and a trainer. “I'm bigger than Kate, but I noticed she was progressing much further than I was in our strength-training workouts. That seemed weird,” he says. Things only got weirder. He had trouble climbing stairs, and his whole right side got weaker. When Jacobs and Riley moved into a new home, he struggled to lift and carry boxes.
Other early signs of Kennedy's disease can include shaky hands, weakness, and muscle pain, says Alejandro Tobon, MD, FAAN, chief of neurology at South Texas Veterans Health Care System in San Antonio. Muscle weakness usually begins in the upper legs and manifests on both sides.
When Jacobs mentioned his symptoms to a friend, the friend thought the problem might be neurologic. “I began to have scary thoughts about Parkinson's, multiple sclerosis [MS], or ALS [amyotrophic lateral sclerosis],” says Jacobs. Because Kennedy's disease is rare, affecting about one in 40,000 people, according to the Kennedy's Disease Association, it can be difficult or take a long time to get an official diagnosis.
Concerned and nervous, Jacobs traveled to the University of Chicago for a series of diagnostic tests whose results might explain his symptoms. After a neurologist conducted a physical examination and took his medical history, Jacobs underwent electromyography (EMG) to assess the condition of his muscles and nerves. “It was uncomfortable and a little scary,” he says. “Medical students were observing my EMG, and as the doctor inserted a small needle in my arm, I could hear the students chattering—I could tell there was something about the results that was getting their attention, and I was irritated.” The EMG revealed ongoing nerve damage associated with Kennedy's disease. “Then the doctor ran a blood test that confirmed I had the genetic mutation,” Jacobs says.
The disease—named for William R. Kennedy, MD, who identified the disorder in 1968—mostly affects men and usually starts between ages 20 and 50, says Dr. Tobon, who is also associate professor of neurology at the University of Texas Health Science Center in San Antonio. “It's caused by a change in the androgen receptor gene on the X chromosome, which affects how certain cells respond to male hormones and leads to problems with muscles, especially those used for movement and speaking and swallowing.”
Early symptoms such as muscle cramps lead to progressive limb weakness, says Kenneth Fischbeck, MD, FAAN, scientist emeritus at the National Institute of Neurological Disorders and Stroke in Bethesda, MD. The progression is slow but eventually leads to severe muscle weakness and dysfunction in the bulbar region, resulting in trouble swallowing and speaking.
