Tara Costa is one of the contestants of the second season of The Biggest Loser: Couples. She is a finance manager based in New York, NY. She came from a single parent home, where she learned to become feisty and independent. Friends describe her as being very charming yet frank at the same time. While working for a cosmetic company, she became a plus-size model, although she has always struggled with her weight throughout her life. Now, she is scared of possibly health problems that her weight may cause, and has taken this chance to finally lose some pounds.

She joined the show with her close friend Laura Denoux, and was part of the Green Team, under Jillian Michaels. Currently, she is part of the Black Team, still under Michaels.
