A food-only menu entry and a combo are not interchangeable servings. Before comparing calories or protein, identify whether the side and drink belong to each number. A lower printed total may simply describe fewer included items.
Make the comparison explicit
Imagine Breakfast A is one fictional sandwich at 330 calories and 20 g protein. Breakfast B is a different sandwich plus a side at 510 calories and 23 g protein. Comparing 330 with 510 answers a complete-order question only if those are the orders you plan to buy. It does not isolate the sandwich difference.
Separate the side when the source allows
If B’s official component table says its sandwich is 360 calories and 21 g protein, the side accounts for 150 calories and 2 g protein in this example. You can then compare sandwiches at 330 versus 360 and complete listed orders at 330 versus 510. Label both views clearly.
Keep the beverage in scope
If the combo includes a choice of drink, a single food-and-side total still may not be the full purchased order. Add the chosen documented beverage or state that it is excluded. Do not assign a default drink without telling the reader.
FDA’s menu-labeling and serving information supports checking the published scope. These are invented values. Use them to learn the accounting method, then use actual source-defined portions for a restaurant decision. GetMacros should compare clearly named orders rather than letting a marketing combo name hide what the recorded figure contains.
