How to Reduce the Calories of Your Sub

There are ways to modify your order to make it a healthier choice.

Start with the Small size: Opting for the smallest size automatically cuts your calories and sodium in half compared to the medium.
Hold the mayo: Mayonnaise is a dense source of calories and fat. Skipping it is one of the easiest ways to reduce your intake.
Go light on the cheese: Reducing the amount of cheese will lower the fat and calorie content.
Opt for wheat bread: Switching from white to wheat bread can slightly reduce calories and is often a healthier overall choice.
Add extra veggies: Load up on extra lettuce, tomatoes, and onions for added volume, fiber, and nutrients without adding significant calories. Extra vegetables add flavor and texture, making you feel full longer.
Pair with a salad, not chips: Choose a side salad with a light dressing to complete your meal without a huge calorie boost.

Understanding the Nutritional Impact

Beyond calories, it's important to understand the overall nutritional impact of the sub. The Jamaican Jerk Turkey sub provides protein, which is beneficial for muscle repair and feeling full. However, its high sodium and fat content, especially in the larger sizes, means it should be an occasional treat rather than a regular meal. For those on a diet, splitting a large sub into two or more portions is a good strategy to manage intake. The high sugar content from the sweet mustard sauce should also be noted.

Conclusion

The number of calories in a Jamaican Jerk turkey sub from Firehouse Subs depends on the size, with counts of 360, 720, and 1,140 for the small, medium, and large versions, respectively. For a more calorie-conscious meal, opting for a small sub and requesting customizations like no mayonnaise and extra vegetables can make a significant difference. While this sub can be a delicious choice, its higher calorie, fat, and sodium levels mean it's best enjoyed in moderation for those monitoring their health. Being aware of the nutritional breakdown allows you to make an informed choice that fits your dietary goals.
