The document discusses building a healthier burger option. It identifies that the current burger deters health-conscious customers due to its high calories, fat, and carbohydrates. The solution is to find lower calorie, lower fat, and lower carbohydrate alternatives for the bun and cheese to create a new burger with fewer total calories, fat, and carbohydrates that would appeal to more customers. The new bun has fewer calories, less fat, and fewer carbohydrates than the original bun. The new cheese also has fewer calories and less fat than the original cheese. When combined, the new burger has fewer total calories, fat, and carbohydrates than the original best-selling burger.
