Which Fish Have the Fewest Calories?
Determining the absolute lowest calorie fish can be difficult due to variations in size, preparation, and whether the fish is wild-caught or farmed. However, based on average serving sizes, a few species consistently rank at the top of the list for leanness and low-calorie content. These are typically white, flaky fish known for their mild flavor.
Flounder and Sole
Flounder and sole are widely considered to be among the lowest-calorie fish available. A 100-gram (3.5-ounce) portion of flounder can contain as few as 70 calories and minimal fat, while still providing a good source of protein. These flatfish have a delicate, flaky texture and a mild, non-fishy taste, making them an excellent choice for those new to seafood.
Cod and Haddock
As members of the cod family, both cod and haddock are exceptionally lean white fish with a moderate firmness. A 3-ounce cooked portion of cod provides around 100 calories, along with an impressive 23 grams of protein. Haddock is also very low in calories, with a 3.5-ounce cooked serving having less than 100 calories. Both are versatile and hold up well to various cooking methods like baking, grilling, and broiling.
Leaner Shellfish Options
While not technically fish, several types of shellfish are also excellent low-calorie protein sources. Steamed or boiled shrimp and scallops, for instance, are very low in calories and packed with nutrients. A 3-ounce serving of steamed scallops has about 95 calories, while a similar portion of steamed shrimp is just under 100 calories.
Low-Calorie Fish Comparison
To provide a clear picture, here is a comparison of some popular low-calorie fish and shellfish based on a standard 100g (3.5oz) cooked serving size. Nutritional values can vary, but this table offers a general guideline.
| Seafood Type | Approx. Calories (per 100g) | Approx. Protein (per 100g) | Notes |
|---|---|---|---|
| Flounder & Sole | ~70-100 | ~15-20g | Very lean and mild-flavored |
| Haddock | ~74-100 | ~15-20g | Mild, slightly sweet flavor |

| Ocean Perch | ~79 | ~15g | Mild, slightly sweet flavor |
| Scallops (steamed) | ~110 | ~21g | Sweet, delicate taste |
| Shrimp (steamed) | ~100-110 | ~20-24g | Popular and versatile |
| Tilapia (cooked) | ~128 | ~26g | Mild, firm texture |
Why Choose Low-Calorie Fish? Health Benefits
Beyond their low-calorie nature, lean fish offer a wealth of health benefits that make them a smart dietary choice. Fish is not only a fantastic source of protein but also provides essential vitamins and minerals that support overall health.
Nutrient-Dense Protein Source
Fish is a high-quality, easily digestible protein source that is crucial for building and repairing muscle tissue. Lean fish like cod and flounder offer a high protein-to-calorie ratio, meaning you get more protein for fewer calories. Fish protein also contains essential amino acids that are vital for metabolic activities and immunity.
Heart and Brain Health
While fatty fish like salmon are renowned for their high omega-3 content, lean fish also provide these beneficial fatty acids, albeit in smaller amounts. Omega-3s help maintain a healthy heart by lowering blood pressure and reducing the risk of heart attack and stroke. These essential nutrients also aid healthy brain function and have been shown to decrease the risk of depression, Alzheimer's disease, and dementia. Even a modest intake from lean fish contributes to these important benefits.
Weight Management
Eating low-calorie, high-protein fish helps you feel full and satisfied, which can prevent overeating and aid in weight management. The thermic effect of food (TEF), or the energy required to digest food, is higher for protein than for fats or carbohydrates, meaning your body burns more calories processing protein-rich meals. This makes lean fish a strategic choice for weight-conscious individuals.
The Best Ways to Prepare Low-Calorie Fish
Cooking methods can significantly impact the final calorie count of your meal. To keep your fish dishes as healthy as possible, avoid deep-frying and opt for preparation methods that require minimal added fat.
- Baking or Broiling: Placing your fish fillets in the oven with a spritz of lemon juice and a sprinkle of herbs is a simple, low-calorie way to cook them. Recipes often involve wrapping fish in parchment paper (en papillote) to steam it perfectly.
- Grilling: Grilling fish adds a delicious smoky flavor without needing much oil. Marinate your fish in a light, low-sugar marinade or simply use lemon, pepper, and herbs.
- Steaming or Poaching: Steaming is one of the gentlest and lowest-calorie cooking methods available. Poaching fish in a flavorful, low-sodium broth or water is another excellent option for retaining moisture and flavor with no added fat.
- Pan-Searing: For a crispy exterior, a non-stick pan with a small amount of healthy oil, like olive oil, can be used to pan-sear fillets. Be mindful of the oil quantity to keep the calories in check.
Conclusion: Your Guide to Healthier Fish Choices
Flounder, sole, cod, and haddock are strong contenders for the title of the lowest calorie fish, offering a lean source of high-quality protein for weight management. These versatile fish can be prepared in numerous healthy ways, from baking and steaming to grilling and poaching. By incorporating these varieties into your diet, you not only manage your calorie intake effectively but also benefit from a powerful array of nutrients that support heart, brain, and overall health. Making simple changes to your cooking methods can ensure your low-calorie fish dish remains a healthy and delicious part of your routine.
