(Newser) – If Kevin Trudeau wants to hawk his book, The Weight Loss Cure They Don't Want You to Know About, over the next 10 years, he'll have to do it from federal prison. The Chicago-based infomercial pitchman was sentenced to a decade in prison yesterday by a judge who rejected his pleas for leniency, citing his decades-long history of fraud and calling him "deceitful to the core," the Chicago Tribune reports. The judge accused him of treating previous court orders as mere "suggestions" or "impediments to be sidestepped, outmaneuvered, or just ignored."

The 50-year-old was found guilty last fall of defying a court order banning him from making false claims about the weight loss book by continuing to air misleading late-night infomercials at least 32,000 times. Prosecutors said he made at least $39 million from sales of the book, which he claimed offered a no-hunger, "diet-free" way of losing weight when it really described a tough, 500-calorie a day diet accompanied by hormone treatments, the AP notes. In his remarks to the court, Trudeau said he was a changed man, although he doesn't seem to be planning a career change. "I have truly had a significant reawakening," he said. "If I ever do an infomercial again ... I promise: No embellishments, no puffery, no lies." (Read more Kevin Trudeau stories.)
