Customize sandwiches and check complete nutrition information.
Subway has marketed itself as the healthy fast-food choice for decades, and the truth is more nuanced. The build-your-own format genuinely lets you make a balanced, vegetable-packed meal, but the same format makes it just as easy to build a sub that rivals any burger once you add the cheese, the creamy sauces and a footlong portion. The control is real, it just cuts both ways.
The menu spans the classic subs and Subway Series specialties, breakfast and sliders, breads and wraps, sides and the sauces. The calculator shows you how each choice (bread, protein, cheese, sauce, size) adds up, so you can land the balanced version rather than the accidental heavy one.
The two biggest levers are obvious once you name them. A six-inch versus a footlong is simply double the sandwich, so for most people a six-inch with a side is plenty. Bread is the next: the leaner breads trim calories versus the cheesy or flatbread options, and the wrap is not automatically lighter, since some wraps carry as much as the bread they replace.
Choosing a six-inch on a leaner bread sets you up well before you even pick the fillings.
This is where Subway can shine. The lean proteins, the turkey, chicken and the egg-white breakfast options, give you a protein-forward sandwich without much fat. The higher-protein specialty subs (the loaded meat builds) push protein impressively high, which is useful if that is your goal, just with more calories and sodium along for the ride. The processed deli meats are higher in sodium, so the leaner roasted options are the better everyday pick.
The vegetable bar is Subway's best feature, and it is essentially free real estate. Piling on lettuce, tomato, peppers, onions, cucumbers and spinach makes the sandwich bigger, more filling and more nutritious for almost nothing. Take full advantage.
The sauces are the lever that quietly undoes a healthy sub. The creamy ones (mayo, ranch, the creamy signature sauces) add up fast, while mustard, vinegar and a light vinaigrette add flavor for little. Sauce on the side, or a lighter hand, is the single most effective tweak on most orders.
Cheese is a modest add that is easy to skip or halve if you are trimming. The sides matter too: a bag of chips and a cookie can quietly double the meal, so choose them on purpose, and the footlong cookie is a dessert in its own right. Breakfast and sliders follow the same rules, lean protein, lots of veggies, light sauce.

It can be, but it is not automatic. The build-your-own format lets you make a lean, vegetable-packed sandwich, but the same format makes it easy to build one that rivals a burger with cheese, creamy sauces and a footlong portion. The bread, sauce and size decide which version you get.
Not necessarily. Some wraps carry as many calories as the bread they replace, so the wrap is not automatically lighter. Check the number, and a six-inch on a leaner bread is often the lighter choice.
Loading on the creamy sauces. Mayo, ranch and the creamy signature sauces add up fast and can undo an otherwise healthy sub. Getting sauce on the side or using a lighter hand, and choosing mustard or vinegar, is the single most effective tweak.
Choose the higher-protein specialty subs or the lean roasted proteins like turkey and chicken, and load up on vegetables. The loaded meat builds push protein high if that is your goal, just with more calories and sodium, so balance it against the rest of your day.
