In today's world, many people find it difficult to get the right nutrients due to busy schedules and the difficulty of controlling their diets. As a result, protein shakes and meal replacements have become increasingly popular, with many people turning to them to help them stay healthy and manage their diets. Amazon is a world-renowned online retailer that offers a wide variety of products and brands, and a recently introduced Korean portable diet management product has attracted attention.

Hanjang's Diet is a product developed by a small business in North Gyeongsang Province, South Korea, and is now available on Amazon, ranking 58th in Amazon's convenience food and beverage category in January 2021, causing a K-food craze.

Capturing the taste of consumers who have become health-conscious due to COVID-19, Hanjang's Diet is a high-protein, low-calorie meal replacement product with five flavors, including green tea and cocoa flavors, that can be easily consumed by adding water. Consisting of 27% protein, 7% carbohydrates and 150 calories, about 1/5 of a regular meal, Hanjang's Diet is a good meal replacement product for consumers with unbalanced eating habits.
