What to Always Avoid at Firehouse Subs
Not every item at Firehouse Subs is worth the calories. These are the orders most likely to derail your macros — high in fat or carbs relative to their protein content.
Watch out for the Smokehouse Beef & Cheddar Brisket (730 cal). At 730 calories with 42g protein, this has a low protein-to-calorie ratio that makes it a poor choice when cutting. If you order it, make sure you are in a surplus and it fits your goal for the day.

Default sides and combos add up fast. At Firehouse Subs, the default sides — fries, chips, sugary drinks — can add 400-600 calories without meaningfully increasing your protein intake. Swap for a side salad, water, or nothing extra when cutting.
