The Nutritional Power of Lean Seafood
Seafood is celebrated for its health benefits, including being a rich source of high-quality protein, essential vitamins, and minerals. For those mindful of their calorie intake, focusing on lean seafood varieties is a strategic choice. High protein content helps with satiety, meaning you feel fuller for longer, which can prevent overeating and aid in weight loss. Additionally, lean seafood is naturally low in fat, particularly saturated fat, making it a heart-healthy alternative to many other protein sources.
Beyond protein, many low-calorie seafood types provide a wealth of other nutrients. For example, cod is a great source of B vitamins, which are crucial for energy metabolism. Shellfish like oysters and mussels offer vital minerals such as iron, zinc, and selenium, which support immune function. By choosing low-calorie seafood, you can create delicious, nutrient-dense meals that support overall wellness without derailing your dietary goals.
A Closer Look at the Lowest-Calorie Seafood Options
The Leanest Fish
Lean white fish are among the top contenders for the lowest-calorie seafood. Their mild flavor makes them versatile for many dishes and appealing to those new to eating fish. Some of the best choices include:
- Cod: A great source of protein with a very low-fat content. A 3.5-ounce serving of Atlantic cod has approximately 82 calories and 18 grams of protein.
- Flounder and Sole: These flatfish are exceptionally low in calories, with around 86 calories and 15 grams of protein per 3.5-ounce serving.
- Haddock: Similar to cod, haddock provides around 74 calories per 3.5-ounce serving.
- Pollock: A popular, low-cost option, Alaska pollock contains around 86 calories and 19 grams of protein per 3.5-ounce serving.
- Orange Roughy: This fish can have as little as 70 calories per 3.5-ounce serving, though mercury levels can be a concern for some.
The Leanest Shellfish
Shellfish are often surprisingly low in calories and fat, while being high in protein and minerals. Remember that preparation is key to keeping them low-calorie.
- Oysters: Often cited as the lowest-calorie seafood, raw oysters contain about 81 calories per 3.5 ounces, depending on the variety. They are also exceptionally rich in zinc.
- Crab: Steamed crab is a very lean choice, with a 3.5-ounce portion containing around 82 calories and 18 grams of protein.
- Shrimp: When steamed or boiled, shrimp is a low-calorie, high-protein option, with about 99 calories and 24 grams of protein per 3.5-ounce serving.
- Lobster: Steamed lobster meat is another excellent, low-calorie option, providing around 89 calories per 3.5-ounce serving.
Cooking Methods for Low-Calorie Seafood
Your choice of cooking method has a significant impact on the final calorie count. The healthiest ways to prepare seafood retain its natural nutrients without adding unnecessary fat or calories.
Best Cooking Methods:
- Steaming and Poaching: These methods add no extra fat.
- Baking and Broiling: Using dry heat, these methods cook seafood evenly and can create a delicious texture.
- Grilling: High-heat grilling gives seafood a lovely char without the need for much oil.
- Air-Frying: A modern and healthy alternative to deep-frying, air-frying can deliver a crispy texture with minimal added oil.
Cooking Methods to Limit:
- Frying and Deep-Frying: These methods cause the seafood to absorb cooking oil, significantly increasing its calorie and fat content. Frying can also damage beneficial omega-3 fatty acids.

Sustainable and Safe Choices
When selecting seafood, sustainability and safety are important considerations. Resources like the Monterey Bay Aquarium's Seafood Watch program can help identify sustainable choices. Concerns about mercury are also valid, particularly for pregnant women and young children. Generally, larger, longer-lived predatory fish tend to have higher mercury levels. Most low-calorie, lean seafood options, such as shrimp, cod, and oysters, are also typically lower in mercury.
Conclusion
Incorporating lean, low-calorie seafood into your diet is an effective and flavorful way to meet protein needs and support weight management goals. Oysters, crabs, cod, flounder, and shrimp consistently rank among the lowest in calories, providing excellent nutritional value. By choosing healthy cooking methods like steaming, baking, or grilling, you can maximize the benefits of these foods without adding unwanted calories from fats. Prioritizing sustainable and low-mercury options ensures you make a healthy choice for both yourself and the environment. Expanding your intake of these lean seafood varieties is a delicious step toward a more balanced and nutritious diet, offering a multitude of health benefits beyond just calorie control.
