Low-Calorie Seafood for a Healthier Diet
Seafood is known as a nutritious food source, offering high-quality protein, vitamins, and minerals. Many varieties are naturally low in calories, which makes them suitable for weight management. Selecting lean options and using healthy cooking methods are key to keeping calories low; fat-heavy preparation can significantly increase the calorie count.
Top Lean Fish Choices
Lean white fish are among the best options for minimizing calorie intake. They are packed with protein but contain very little fat, which keeps their caloric density low.
- Cod: This mild, flaky fish is a nutritional powerhouse. A 3-ounce serving of cooked Atlantic cod contains approximately 90 calories and 19 grams of protein. It is also a great source of B vitamins and selenium, making it a valuable addition to your diet.
- Flounder and Sole: These flatfish are exceptionally lean, with a 3.5-ounce portion containing under 100 calories. Their delicate, flaky texture and mild flavor make them a versatile choice for many low-calorie recipes.
- Haddock: Similar to cod, haddock is a lean, white fish with around 90 calories per 3-ounce cooked serving. It's a reliable source of protein and essential nutrients.
- Pollock: Another affordable and lean white fish, Alaska pollock provides about 86 calories and 19 grams of protein per 100-gram serving. It's an excellent source of lean protein and minerals.
The Leanest Shellfish Options
Shellfish can also be a fantastic low-calorie, high-protein food. Preparation is especially critical here, as added butters or oils can quickly inflate the calorie count.
- Oysters: As one of the lowest-calorie seafoods, a 100-gram serving of oysters contains as little as 81 calories. They are also rich in minerals like zinc and iron. Steaming them is the best way to keep calories down.
- Crab: Steamed crab meat is a light and lean choice, offering around 82 calories per 100-gram serving. It is a good source of protein and minerals, but is often served with high-calorie sauces, so be mindful of preparation.
- Shrimp: A 100-gram serving of cooked shrimp has about 99 calories and is very high in protein. Shrimp also provides beneficial antioxidants like astaxanthin. The key is to choose steamed or boiled shrimp and avoid frying.
- Scallops: Boiled or steamed scallops offer about 114 calories per 100-gram serving and are a good source of lean protein. They are naturally low in fat, but pan-searing with heavy oil will increase calories.
The Importance of Cooking Method
Even the leanest seafood can become a high-calorie dish when prepared improperly. For instance, while a 3-ounce serving of steamed shrimp has about 101 calories, the same amount that is battered and fried can skyrocket to over 200 calories. To keep meals low in calories, focus on these methods:
- Steaming: This is a great way to cook shellfish like mussels and clams, as it requires no added fat.
- Boiling: This is ideal for cooking shrimp and crab, retaining their natural flavor and keeping calories to a minimum.
- Grilling and Broiling: Excellent for firm fish fillets, adding a smoky flavor without excess oil.
- Baking: This is a simple, hands-off method for cooking fillets with minimal added fat. To retain moisture, cook with herbs and a splash of lemon juice.

Note: Calorie counts can vary based on species, preparation, and portion size. Figures are based on approximate data from a 3-ounce serving unless otherwise noted.
Making Smarter Seafood Choices
Beyond calories, consider the overall nutritional profile. While lean white fish have fewer calories, fattier fish like salmon and mackerel provide higher levels of omega-3 fatty acids, which are crucial for heart and brain health. A balanced approach might involve incorporating both types into your diet.
- Sustainably Sourced: Choose seafood certified by organizations like the Marine Stewardship Council to ensure you're making an environmentally friendly choice.
- Wild-Caught vs. Farmed: Wild-caught fish may sometimes be leaner and lower in calories than their farmed counterparts, though this can vary by species. Both can be part of a healthy diet.
- Portion Control: Pay attention to portion sizes. Even low-calorie options can add up if overconsumed. A standard 3- to 4-ounce serving is typically recommended.
Conclusion
Those seeking the absolute lowest calorie options should consider certain types of steamed shellfish, such as oysters, crab, and shrimp, along with lean white fish like flounder, cod, and haddock. The best strategy is to enjoy a variety of seafood, paying attention to mindful preparation. By focusing on steaming, grilling, and baking rather than frying, you can maximize the nutritional benefits while keeping meals light and delicious.
