Jimmy John's Calories: The Best Low-Calorie Subs and Unwich Swaps

The best low-calorie order at Jimmy John's is the Unwich, a classic sub wrapped in lettuce instead of bread. A Turkey & Cheese Unwich runs just 230 calories with 27g of protein, which is a near-perfect lean-protein ratio. If you want actual bread, the Little John size (a 4-inch roll) keeps most subs between 300 and 350 calories, and the Plain Slims line sits around 440. Below I break down every option by size so you can order on autopilot.

Why Jimmy John's is easy to eat lean

Most of the calorie damage at a sandwich shop comes from two places: the bread and the mayo. Jimmy John's bakes a decent-sized French roll, and their standard subs get a generous squirt of mayo plus oil and vinegar. Strip those out and the actual meat-and-veggie core is genuinely low calorie. That's the whole trick here.

The menu is also refreshingly modular. You pick a protein, then pick a vehicle: full-size sub, Little John (smaller roll), Plain Slim (sub with just meat and cheese, no veggies or sauce), or Unwich (lettuce wrap). Same filling, wildly different calorie counts. Compared to heavier fast-food plays like a McDonald's combo or a loaded Chick-fil-A order, a well-built Jimmy John's sub is one of the cleaner drive-adjacent lunches out there.

The lowest-calorie Jimmy John's orders, ranked

Here's how the key options compare. The #2 Big John (roast beef) and #4 Turkey Tom are two of the most popular subs, so they're a good way to see what each size does to the numbers.

The pattern is clear. The Unwich is the king of calorie efficiency: 230 calories for 27g of protein means roughly 47% of its calories come from protein, which is rare for anything that tastes this good. The Little John is the best move if you need bread but want to stay under 350. And a full sub, while not outrageous at 560, is more than double the Unwich for the same meat.

The Unwich: your single best swap

If you take one thing from this article: order it as an Unwich. Jimmy John's wraps any sub in a big iceberg lettuce shell, and the Turkey & Cheese version is the proof of concept at 230 calories and 27g protein. You keep the turkey, the cheese, the veggies, and even the standard mayo, and you still land lighter than a small order of McDonald's fries (230 cal for basically zero protein).

The Unwich isn't just about cutting calories, it's about swapping empty carbs for protein. A full sub's French roll adds roughly 300-plus calories of mostly refined carbs. Dropping it takes a 560-calorie #2 Big John down to near-Unwich territory while keeping all 35g of that protein. If you lift and track macros, this is the single highest-leverage fast-food swap there is.

One heads-up: the Unwich can get messy, and if you load it with extra mayo and oil you'll claw some calories back. Ask for mustard, hot peppers, and extra veggies instead. Those are free from a calorie standpoint and make the wrap actually taste like a meal.

If you want bread: go Little John or Plain Slim

Not everyone wants a lettuce wrap, and that's fine. You have two solid bread options.

Little John (the 4-inch)

The Little John is a half-size sub on a smaller roll. The Little John #2 Big John lands at 330 calories with 21g protein, which is a tidy lunch if you're pairing it with other food or just not that hungry. It's the best balance of "real sandwich" and "reasonable calories" on the board.

Plain Slims

Plain Slims are full-length subs with just meat and cheese on bread: no veggies, no sauce. The Plain Slims #4 Turkey Tom is 440 calories with 27g protein, and the roast beef Plain Slims #2 Big John hits the same 440 with an even better 30g protein. These are a good pick if you want a filling sandwich and don't care about toppings. Add free veggies (lettuce, tomato, cucumber, onion) yourself for volume without meaningfully moving the calories.

Watch the sides and drinks

The sub is only half the order. Sides are where a "healthy lunch" quietly turns into a 900-calorie affair.

• Kosher Dill Pickle: 5 calories. Basically free, salty, satisfying. Order it with zero guilt.
• Thinny Chips: 130 calories. The lighter chip option if you need a crunch.
• Jimmy Chips (regular or BBQ): 160 calories. Not crazy, but the Thinny Chips save you 30 calories for the same vibe.
• Unsweet Iced Tea: 3 calories. This is your drink. Soda will add 150 to 300 calories and undo the entire point of the Unwich.

Build a smart combo like Turkey & Cheese Unwich (230) + pickle (5) + unsweet tea (3) and you're eating a complete, protein-heavy lunch for under 240 calories. That's lower than most single menu items at Chick-fil-A or a basic Dunkin breakfast sandwich.

How to build your own low-calorie order

You don't have to memorize anything. The framework:

1. Pick a leaner protein base. Turkey and roast beef are your lightest, highest-protein proteins. Steer away from double-meat clubs and anything with bacon or salami if calories are the priority.
2. Choose your vehicle. Unwich (lightest) > Little John > Plain Slim > full sub.
3. Modify the sauce. Mustard, vinegar, and hot peppers are near-zero. Mayo and oil add up fast, so ask for light or none.
4. Pile on free veggies. Lettuce, tomato, cucumber, onion, and peppers add bulk and fiber for almost no calories.

If you want to lock in the exact numbers for your specific build (say, a #4 Turkey Tom Unwich with extra cheese), log it in TrackBiteX, which has the full Jimmy John's menu plus 80-plus other US chains built in. Swapping bread for lettuce in the app shows you the calorie drop instantly, which makes the smart choice obvious before you even order.

The bottom line

Jimmy John's is one of the more macro-friendly fast lunches if you know the levers. The Unwich at 230 calories and 27g protein is the headliner, the Little John at 330 is your bread-eating compromise, and Plain Slims at 440 keep protein high with minimal extras. Keep the pickle, grab Thinny Chips over regular if you need a crunch, and drink the unsweet tea. Track it once and the whole menu becomes easy to navigate.
