Calories and Nutrition


I would like to start with a review of the calories. Here is a breakout for how many calories are derived from each macronutrient (fat, carbs, and protein).

Calories in Big John Sandwich

There are 500 calories in an 8″ Jimmy John’s Big John® on French Bread. Fat and carbohydrates each contribute about 39% of the total calories. Protein makes up the remaining 21% of the calories.

The composition of calories by macronutrient is broken down as follows:

  • Fat: 195 calories
  • Carbs: 195 calories
  • Protein: 105 calories
  • Total: 500 calories per 8″ sandwich

The caloric breakout by nutrient is a rounded estimate based on the nutrition facts label sourced from the restaurant. Calories may vary by location, as a result of how it’s prepared, or due to topping choices.

Sliced Wheat Bread

For orders of the Big John on sliced wheat bread, total calories increase to 550.

Giant 16″ Doubles Calories

The Giant serving is essentially twice the size as a regular. This larger 16″ sub, has 1,000 calories in the sandwich served on fresh baked French bread.

Reduced Calorie Big John

If you’re watching the number of carbohydrates and calories in your diet, check out the Jimmy John’s Unwich® options. An Unwich version of the Big John includes the same hand-sliced roast beef with all the fixings.

The only difference – and it’s a big one as far as calories are concerned – is that everything is wrapped in lettuce instead of bread. Because of that change, the Big John Unwich has only 270 total calories. That’s total calories, about half the number of calories as the traditional 8″ Big John.
