Footnotes
- ^ The heaviest contestant across all international versions of the show came from Australia's second season, with a starting weight of 216.3 kg (477 lb).
- ^ This title was previously held by Jerry Lisenby of Season 4, who lost 31 pounds (14 kg) in the first week.
- ^ Neil Tejwani, from season 4, lost 33 pounds (15 kg) in week 8, but as the result of gaining 17 pounds (7.7 kg) the previous week, due to water loading, so this record may not have been counted, and would not count under current rules, which reset the weight of a contestant who has gained weight back to what it was before that weight gain for the following week's weigh-in.
- ^ At the time of taping, the record for weight-loss at the ranch is 144 pounds, set by Roger Schultz, from The Biggest Loser: Couples, who went from 363 pounds to 219 pounds.
