The official Biggest Loser website has just posted the first two sneak peek advertisements for the 2013 season.

You can watch them by clicking here.

There’ll likely be more coming in the days and weeks ahead.

This year it will be parents and children, it seems. Gerald and Todd are father and son and poor Todd comes home from school upset most days as he’s been the subject of bullying due to his weight.

While he may go back to school thinner, being on the show probably isn’t going to do him any favours when it comes to being bullied. So let’s hope Gerald and Todd get Shannan as their trainer!

The other pair revealed today are father-daughter team Sam and Jess. Jess has recently had a stroke at the age of 21. As you might imagine, that’s a bit scary and she’s looking to change her life, etc.

If you’ve seen any ads start popping up or you notice more teasers go up on the official site, let us know in the comments!
