The Biggest Loser season 13

Contestants

The "Total Votes" column tracks how many elimination votes each contestant received. Some players were sent home automatically as the final member of their trainer's team, receiving no votes. Others were eliminated without any votes after landing below the Red Line. One participant chose to leave the competition and did not return for either the finalist battle or the finale. A single team failed a challenge to earn contestant status, but came back in Week 5 for a second chance weigh-in, successfully losing 50 pounds together to re-enter.

Weigh-ins

Contestants are listed in reverse chronological order of elimination. Standings include Week's Biggest Loser (Team or Individuals), Week's Biggest Loser and Immunity, Immunity (Challenge or Weigh-in), and Results from At-Home players. A contestant withdrew before weigh-in. BMI categories range from Underweight (less than 18.5) to Obese Class III (greater than 40).
