 So I thought it would be great to bring in health expert Sonia Jones to the show. Sonia is an author, motivator, speaker who has lost over 144 pounds as a finalist on season 16 of NBC's The Biggest Loser. Sonia was the only female finalist in the show's 16th season and lost the show only by, get this, one one-hundredth of a percentage of weight, which is crazy to think about and how they can even weigh that way.
