However, 'Juvis' alleged that after he reached his target weight, he stopped properly attending the weight loss program, citing busy schedules. As a result, he gained back over 10kg (22lb) within 4 months. Even after the contract, he was supposed to attend a yoyo prevention program every week, but never attended such either. 

The court acknowledged that customers who saw Kim Tae Woo's weight gain started doubting the 'Juvis' program, and either tried to get refunds or cancelled their consultation. However, the court also acknowledged that he also had positive results from his ad campaign, and so therefore would have to pay 'Juvis' back half of the contract pay, of 65 million KRW (58,600 USD).
