Seo In-young discusses weight regain and first subway experience

Singer Seo In-young recently shared updates regarding her health and lifestyle on her YouTube channel, ‘Gaegwacheonseon Seo In-young’. She revealed that after losing 14kg to prepare for the Waterbomb festival and undergoing liposuction, she has experienced weight regain, noting that she has ‘let things go’ since the event.

The discussion highlighted the physiological challenges of rapid weight loss, such as hormonal imbalances involving leptin and ghrelin, which can trigger increased hunger and the yo-yo effect. Additionally, Seo In-young shared personal anecdotes about her upbringing, claiming she had never used the Seoul subway system in her 40 years of life due to her family's previous wealth, before attempting to navigate public transit for a video challenge.

In the same content, she documented her first attempt at using the subway, seeking assistance from citizens to learn how to purchase tickets and navigate turnstiles.
