South Korea Weight Loss and Weight Management Market Size

The South Korea weight loss and weight management market is projected to grow at a compound annual growth rate (CAGR) of 5.80% during the forecast period of 2025–2034. As health consciousness rises across demographics and digital health platforms become more prevalent, the market is witnessing robust demand across dietary solutions, equipment, and service-based models.

Market Share Distribution

South Korea’s weight management industry is broadly segmented into diet, equipment, and service-based categories. Among these, diet-based products, particularly meal replacements and protein supplements, dominate the market due to their convenience and rising preference among urban professionals and aging populations.

In terms of equipment, cardiovascular training equipment and body composition analyzers lead the segment, driven by fitness center adoption and home-based wellness trends. Service-wise, fitness centres and online weight loss programs are gaining a larger share due to hybrid fitness models and increasing digital engagement.

  • Rising obesity and lifestyle-related health issues: The prevalence of obesity has become a growing concern in South Korea, especially among young adults and middle-aged individuals.

  • Government health initiatives: Programs promoting physical activity, nutritional awareness, and preventive healthcare are shaping consumer behavior.

  • Digital fitness transformation: Wearable fitness trackers and app-based platforms are enabling users to monitor calorie intake, physical activity, and health metrics in real time.
