The document discusses building a healthier burger option by finding alternatives to the standard bun and cheese that contain fewer calories, fat, and carbohydrates. It shows that switching to an alternative bun reduces calories from 260 to 140, fat from 5g to 2g, and carbohydrates from 45g to 27g. An alternative cheese provides fewer calories at 70 compared to 125, and less fat at 4g instead of 9g. These changes result in an improved burger with lower total calories of 410 instead of 585, total fat of 19g rather than 27g, and total carbohydrates of 28g rather than 46g.
