The document proposes building a healthier burger option by finding alternatives to the existing bun and cheese that have lower calories, fat, and carbohydrates. Specifically, the alternative bun has 140 calories, 2g fat, and 27g carbs compared to 260 calories, 5g fat, and 45g carbs in the original bun. The alternative cheese has 70 calories, 4g fat, and 1g carbs versus 125 calories, 9g fat, and 1g carbs in the original cheese. Combining these alternatives results in a "better burger" with 410 calories, 19g fat, and 28g carbs rather than 585 calories, 27g fat, and 46g carbs in the original.
