Japanese Katsudon Diet Thumbnail

Create a bright and visually striking Japanese-style YouTube video cover for a diet video on the theme of weight loss, using a simple left-right split composition. The left side features a white background filled with an oversized, bold Japanese title, stacked vertically and diagonally for optimal readability: the top line is a large, bright orange "カツ丼" (katsudon) with a thick white outline and soft shadow; below is a dark brown "食べても" (eat it); followed by a bright pink "太らない方法" (too unpleasant method) with a white outline and yellow underline; at the bottom is a large red-orange "5," next to a dark brown "选!" (choose!) with a white outline. Add small yellow sparkles and manga-style emphasis symbols around the title. In the lower left corner, place a simple flat illustration depicting a woman above waist height, wearing a yellow vest and with brown hair tied in a ponytail, making an "OK" gesture against a light yellow circle background. On the right is a close-up of an enticing pork cutlet rice bowl photographed under warm light: a ceramic bowl with blue vertical stripes holds a golden-brown fried pork cutlet topped with egg, onion, and rice, glistening with sauce and visible rising steam, garnished with a single green herb leaf. In the upper right corner, a white circular badge with a yellow dotted border contains the endearing handwritten Japanese phrase "おいしく楽しく♪ 贤くコントロール!", surrounded by a yellow emphasis mark. At the bottom edge, a light cream-colored horizontal information bar is added, with five circular icons and five labels evenly distributed from left to right: a salad bowl icon with the text "Good food in salads", a scale icon with "Be aware of your own health", a walker icon with "Exercise in moderation", a water cup icon with "Enjoy water", and a clock icon with "Make time for eating". The design employs a glossy commercial cover aesthetic, warm-toned food photography, thick-outlined fonts, a cheerful health-themed color scheme, and a high-contrast design optimized for social media click-through rates.
