These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Harsher in Hindsight: Filipe (season 7) accused Jillian for providing drugs to the contestants. In season 15, Jillian's team was penalized for a week because Jillian provided caffeine supplements to her team.
Although some of the viewers thought that it was a elaborate set up for bringing back Ruben Studdard from American Idol.
Also counting that the season was dubbed "No Excuses", and they had what was, without a doubt, the biggest group of whiny competitors, full of excuses. Very few contestants were liked, and the ones who received the most Scrappy status amongst fans were those in Conda's alliance, such as her brother Jeremy and friend Kim, who were both rude and abrasive, and a church preacher who condemned lying and manipulation from others while indulging on it himself.
And the final three? Conda, her brother Jeremy, and Kim. That's right, the three potential winners were three of the most hated contestants of an already hated season.

Tear Jerker: Several moments in every season, for the contestants and trainers as well as the viewers.
Win Back the Crowd: The 15th season, Second Chances 2. For one, the show is finally back to being simply an hour long, as oppose to the tiring two hour length. The season also adds a new rule, in that the contestant with the lowest percentage on the losing team always goes home (save for Trainer Saves). This aspect means that there's no voting, and a LOT less drama in the show.
The Woobie: Trainer Shannon in the Australian version had a nightmare season 7 (Singles). Starting out with the male under-25's team, including Ryan, the heaviest contestant in Biggest Loser history, he knew from the get-go he'd have his work cut out for him. What he didn't count on was having one contestant leave the competition early in favor of taking a $20,000 temptation, having Ryan be eliminated the very next week, being forced to expel the only decently-functional man on his team not long after for a severe breach of the rules, and then having the other teams gang up on his last standing member just as he was starting to get the act together, resulting in his entire team being eliminated while the others all had three members apiece left in the game. The culminated in a distraught Shannon storming out of the Biggest Loser compound, remarking he felt like a failure as a trainer.
Jillian had the same issue at the beginning of season 14. The very first last chance work out, one of her team members quits. The first weigh in, her team loses, and since there is a red line that weak, one of the contestants she felt the best about, TC, was sent home. Second week, the same thing happened, but with Nathan instead of TC. Her team (now down to two, compared to the 5 of both of the other teams), got a reprieve in week 3 due to a surprise weight loss by Pam, but lost the weigh-in of week 4, sending Pam home, leaving her with one member (Danni), while Bob had 5 and Dolvett had 4. Luckily, things soon turned around, and that one team member made it to singles. Guess what? Danni won.
