Host of Biggest Loser Has Major Heart Attack

Fitness trainer Bob Harper, host of NBC's The Biggest Loser, says he's recovering from a serious heart attack that left him unconscious for two days, the AP reports. Harper tells TMZ he was working out in a gym in New York City this month when he collapsed. He says a doctor who also was in the gym performed CPR on him. The 51-year-old Harper says he spent eight days in a New York hospital and hasn't yet been cleared to fly home to Los Angeles. Harper adds that it's his genes, not his lifestyle, that led to his heart attack: His mom died from a heart attack.

But a source tells Us Weekly the fitness buff "pushes himself too hard," which the source feels may have contributed to the attack. On Wednesday, Harper posted a pic of a scented candle burning on Instagram with the caption, "My word of the day ... LUCKY." Harper has been a fixture on all 17 seasons of The Biggest Loser. He served as a trainer on the show from 2004 to 2015 and took over hosting responsibilities for the reality-TV weight-loss program from Alison Sweeney in 2015. (More The Biggest Loser stories.)
