The document discusses building a healthier burger option by replacing the standard bun and cheese with alternatives that are lower in calories, fat, and carbohydrates. The current bun contains 260 calories and 5g of fat, while the proposed alternative bun has 140 calories and 2g of fat. Similarly, the current cheese has 125 calories and 9g of fat, whereas the alternative cheese provides 70 calories and 4g of fat. By making these ingredient substitutions, the total calories are reduced from 585 to 410, total fat decreases from 27g to 19g, and total carbohydrates are lowered from 46g to 28g.
