What’s the average starting weight on The Biggest Loser Australia?

Angus Kidman 17 September 2015

TBL

We've analysed the data across 10 seasons of TBL. How have contestant starting weights changed over time?

The Biggest Loser returned to Australian TV screens this week for its 10th season, TBL: Families. That meant we got to see 16 overweight contestants forced to jump on the scales in public and disclose just how obese they are.

This year's heaviest starter is Johnee, who weighed in at 215.7kg. That's an enormous number, but not the biggest in the history of the show. That dubious honour goes to Kevin from Season 8 in 2013, who started off at 254.7kg. Three other contestants, all men, have also topped Johnee's number: Damien in 2011 (234.4kg), Ryan in 2012 (228.4kg) and Damien in 2007 (216.3kg).

That got us thinking: How has that pattern changed over time? We've crunched the numbers to identify the average and median weight for a starting contestant on The Biggest Loser, and find out which seasons had the heaviest contestants. Plus, we've put every single contestant into a sortable interactive table so you can see how they stack up.

TBL starting weights averages and medians

The table below shows the average and median weights and ages for contestants over the 10 seasons of The Biggest Loser Australia to date. We've also broken out separate data for males and females, since male contestants will typically be heavier anyway.

Average weight142.4kgMedian weight136.4kg
Average age32.5Median age31.0
Average weight (male)158.2kgMedian weight (male)154.6kg
Average age (male)34.0Median age (male)34.0
Average weight (female)127.7kgMedian weight (female)121.9kg
Average age (female)31.1Median age (female)28.0

As you'd expect, the median weights are lower than the average, and the female figures are lower than the males. Still, a median starting weight of 136.4kg confirms that everyone competing on The Biggest Loser is dangerously overweight.

Has that become worse over time? Here's the average and median weight across each of the 10 seasons:

SeasonAverage starting
weight (kg)
Median starting
weight (kg)
1 (2006)174.7173.0
2 (2007)140.7136.4
3 (2008)140.8135.2
4 (2009)134.2134.1
5 (2010)142.2138.8
6 (2011)137.6132.0
7 (2012)143.5140.6
8 (2013)138.9131.8
9 (2014)137.0131.1
10 (2015)145.0137.9

Season 1 remains by far the heaviest season, with a median weight of 173kg. Season 1 had the smallest number of contestants of any season, so that may have skewed the numbers. Two other years have seen a heavier starting median than the current series: 2012 and 2010.

Every TBL contestant's starting weight
