How to interpret this low calorie list
25 of 172 indexed Potbelly records (15%) meet this page’s numeric screen. Inclusion only means that the listed serving satisfies the category rule; it does not establish that the item is a complete meal, medically appropriate, well tolerated, or better than every excluded item.
Results remain ordered by the full six-factor GLP Food Score rather than by calories alone. That distinction matters because two qualifying items can differ substantially in protein, net carbohydrates, sugar, fiber, total fat and calories. Use the comparison table to shortlist options, then open the item record to verify its serving basis, source status, tradeoffs and current restaurant details.
