If you've ever been on a diet...or try to live a healthy lifestyle...you've been faced with this issue. Maybe you're on a road trip, or really pressed for time. What is the healthiest choice to make at a fast food restaurant. Here is a "go to" list.

McDonald's

Artisan Grilled Chicken Sandwich — 360 calories

360 calories — pretty low as far as lunch items go; you might want to pair this with a yogurt, a small salad, or some fresh fruit

33g of protein — a hefty amount to strengthen muscles and fill you up

6g of fat — not too low, not too high

43g of carbs — roughly 14% of your daily allowance

960mg of sodium — a little under half your daily allowance

Opt for a sandwich with grilled rather than fried meat, and hold the mayo to curb your fat intake.

Burger King

BK Veggie Burger. No Mayo

310 calories — pretty low as far as lunch items go; you might want to pair this with a yogurt, a small salad, or some fresh fruit.

22g of protein — a hefty amount to strengthen muscles and fill you up

7g of fat — not too low, not too high

42g of carbs — roughly 14% of your daily allowance

990mg of sodium — close to half your daily allowance

Overall at this restaurant, the same rules as McDonald's apply: Avoid mayo and fried options and go for sandwiches instead of meals.

Wendy's

Asian Cashew Chicken Salad, Full Size

380 calories — on the low side

36g of protein — a hefty amount to strengthen muscles and fill you up

14g of fat — on the higher side, but not a deal-breaker

32g of carbs — pretty high and largely from sugar; watch your snacks

1070mg of sodium — roughly half your daily allowance

Not all of Wendy's salads are on the healthier side but this one is a winner!

Taco Bell

Fresco Chicken Burrito Supreme

340 calories — pretty low as far as lunch items go; you might want to pair this with a yogurt, a small salad, or some fresh fruit

19g of protein — a pretty good amount to strengthen muscles and fill you up

8g of fat — not too low, not too high

49g of carbs — roughly 16% of your recommended daily allowance

1060mg of sodium — close to half your recommended daily allowance

Taco Bell has expanded their healthier offerings with its "Fresco" menu, which essentially swaps the sour cream and cheese in popular items for sale.

Subway

6-inch Turkey Breast Sub. No Cheese. Add Avocado

340 calories — pretty low as far as lunch items go; you might want to pair this with a yogurt, a small salad, or some fresh fruit

9g of fat — not too low, not too high

49g of carbs — roughly 16% of your daily allowance

670mg of sodium — not bad; much lower than competing items at Chipotle or Taco Bell

"Eating fresh" is pretty easy at this chain, where you can get lean meats or just fresh veggies on whole-wheat bread with a variety of low-calorie, low-fat dressings.

Chipotle

500 calories — not too low, not too high
