A new batch of couples arrive at the ranch and are shocked to learn they'll be split up to compete against each other in the Season 13 premiere. The new round has a "No Excuses" theme, and the trainers address the reasons the contestants are overweight.

The teams bet on the percentage of weight they think they'll lose in order to gain an advantage at the weigh-in. Elsewhere, the contestants learn to shop for healthful foods; the teams compete in a puzzle-based challenge; and Dr. Huizenga performs sobering health assessments.

A Chinese-buffet temptation offers the winner a two-pound advantage at the weigh-in and an opportunity to match up players for a gym challenge. Later, the teams compete in a water-transfer challenge for the chance to video chat with loved ones; a player makes a shocking decision.
