In conjunction with the new season premiere, "The Biggest Loser" is partnering with General Mills and Feeding America to launch the Pound For Pound challenge, an initiative that encourages Americans to lose weight and feed the hungry. For every pound viewers pledge to lose this new year, a pound of groceries will be delivered to a local food bank. The Pound for Pound Challenge gives Americans the opportunity to fight the hunger crisis and help families in their own communities by simply pledging to lose weight and getting healthy.

This week kicks off with a temptation that host Alison Sweeney tells the contestants will allow one player to reunite with their teammate at home and bring their trainer with them. But the reunion doesn't go exactly as planned when fireworks erupt between the two teammates after one player accuses the other of not doing all she can to stay on the ranch. Meanwhile the contestants check in with Dr. Huizenga to see how far they've come - and how many medications they no longer need from the first three weeks of weight loss. Then a wild jump rope-like challenge results in immunity at this week's weigh in for the winner, followed by a surprising elimination that sends another contestant packing.
