Should You Eat the Whole Sandwich?

At 370 calories, a Burger King fish sandwich is not an extremely high-calorie meal. However, it may be excessive for some people’s diets or for a child’s meal.

Here are some tips on managing portion size with a fish sandwich:

  • Split the sandwich in half and save part for later.
  • Share the sandwich with a friend or family member.
  • Remove the top bun to cut the carbs and calories in half.
  • Pair with a side salad instead of fries to help fill up.

Using these techniques can effectively cut the calories in half while still enjoying the sandwich. Portion control is key for managing your daily calorie intake when eating fast food.

Should You Drink a Soda With It?

It is not recommended to pair a sugary soda with a fish sandwich. A medium 21 oz. soda from Burger King contains about 250 calories. This would bring the total meal over 600 calories, which is very high.

Some better drink options include:

  • Water
  • Unsweetened iced tea
  • Diet soda
  • Low-fat milk

Avoiding empty liquid calories is an easy way to cut down on your overall caloric intake. Get used to not ordering soda with your meal.

Healthier Sides to Order

To make your fish sandwich meal healthier, choose nutrient-dense sides and avoid fries. Here are some better sides to complement your sandwich:

  • Fresh fruit cup
  • Side salad with light dressing
  • Baked potato
  • Corn on the cob
  • Mashed potatoes
  • Steamed veggies

Pairing your sandwich with vegetables, a salad, or fresh fruit instead of fries can help add vitamins, minerals, and fiber without spiking calories.

How Many Times a Week Can You Eat It?

It is recommended to limit fast food fish sandwiches to no more than once or twice per week. Any more frequently than that may lead to excessive sodium, fat, and calories over time.

Here are some general guidelines on how often you can healthily eat a fish sandwich from Burger King or similar chains:

  • Sedentary adults: Once a week
  • Moderately active adults: 1-2 times per week
  • Very active adults: 2-3 times per week
  • Children: Once a week
  • Pregnant or breastfeeding women: Once a week

Keep your consumption within these limits to keep fish sandwiches as an occasional treat in an overall balanced, healthy diet.

Healthier Alternatives to Consider

For a lower calorie, more nutritious alternative to a fish sandwich, consider these options:

  • Grilled chicken sandwich
  • Veggie sandwich
  • Salad with light dressing
  • Baked potato with toppings
  • Yogurt parfait
  • Fruit and nut bowl

Choosing grilled instead of fried proteins, loading up on veggie toppings, and pairing with fresh produce can satisfy your craving while providing fewer calories and more nutrition.


A Burger King Fish Sandwich contains about 370 calories for a medium-sized sandwich. This calorie count can vary based on serving size, ingredients, and preparation method. While reasonably low in calories for fast food, a fish sandwich is best enjoyed in moderation as part of an overall healthy lifestyle. Use portion control, avoid sugary drinks, and balance it out with nutritious side items to keep your meal as healthy as possible!
