Protein at In-N-Out

In-N-Out publishes a famously short menu, and its protein ladder is just as short: a Hamburger is 16g, a Cheeseburger 20g, and a Double-Double — two patties, two slices of American cheese — 34g. Protein Style swaps the bun for lettuce, which takes a Double-Double from 42g of carbs down to 12g while still leaving 30g of protein.

About the “Calculated” rows

In-N-Out doesn’t publish nutrition for these items. Their numbers are calculated from In-N-Out’s own published rows — not tabled by In-N-Out directly:

3x3 (Three Patties, Three Cheese) — Double-Double w/ Onion plus one extra patty + cheese slice. The cost of that extra pair is In-N-Out's own Double-Double minus its Cheeseburger (610−430 cal, 34−20 g protein), the only difference between those two published rows.
4x4 (Four Patties, Four Cheese) — Double-Double w/ Onion plus two extra patty + cheese pairs, each priced at In-N-Out's published Double-Double minus Cheeseburger difference (+180 cal, +14 g protein per pair).
Flying Dutchman (Two Patties, Two Cheese, No Bun) — Two patty + cheese pairs and nothing else. Each pair is In-N-Out's published Double-Double minus Cheeseburger difference (180 cal, 14 g protein). Cross-checks against a second published path: Double-Double Protein Style (460 cal, 30 g) less the lettuce, tomato and spread it carries (100 cal, 2 g) lands on the same 360 cal / 28 g.
