The document discusses building a healthier burger option by finding alternatives to the standard bun and cheese that contain fewer calories, less fat, and fewer 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, and an alternative cheese with 70 calories instead of 125, 4g of fat instead of 9g, and the same 1g of carbohydrates would result in an improved burger with 410 total calories instead of 585, 19g of fat instead of 27g, and 28g of carbohydrates instead of 46g.
