Create a realistic, eye-catching book cover for a digital eBook titled 'The Ultimate Weight Loss Guide'. The cover features a smiling, fit woman holding a fresh bowl of colorful salad, standing in a bright, modern kitchen with soft natural lighting. Use vibrant and healthy colors like green, white, and light yellow to convey freshness and vitality. The style is photorealistic, clean, and professional, with space at the top for the title and at the bottom for the subtitle. The format is vertical, ideal for eBook covers (1600x2560 pixels)
