With Nutrisystem heading into the diet industry's most lucrative time of year, the U.S. seller of pre-packaged calorie- conscious meals will put Marie Osmond and Dan Marino on the back burner and use testimonials from customers instead.

"These are real people, we want them to inspire others," Chief Executive Officer Joe Redling said in an interview.

The new campaign marks the first time in Nutrisystem's 38- year history that it has taken a break from using celebrities to pitch its meals, priced at $299 for a month's supply.
