The document proposes building a healthier burger option by finding alternatives to the existing bun and cheese that have fewer calories, fat, and carbohydrates. It shows that switching to an alternative bun that has 140 calories instead of 260, 2g of fat instead of 5g, and 27g of carbohydrates instead of 45g, combined with alternative cheese having 70 calories instead of 125, 4g of fat instead of 9g, and 1g of carbohydrates instead of 1g, would result in a new burger having 410 calories instead of 585, 19g of fat instead of 27g, and 28g of carbohydrates instead of 46g, providing a healthier choice for health-conscious customers.
