3 min read

With only 139 calories in a 3-ounce serving of cooked octopus, it is considered a very lean protein source. This remarkable cephalopod offers a dense nutritional profile with minimal fat, making it a surprisingly healthy and low-calorie addition to your diet.

Quick Summary

Octopus is a low-calorie, high-protein seafood rich in essential vitamins and minerals like B12, selenium, and iron. Its nutritional value remains lean, provided the preparation method avoids excessive fats. A key factor is selecting healthy cooking techniques to maximize its health benefits while keeping calories low.

Key Points

  • Low in Calories: A 3-ounce serving of cooked octopus contains only around 139 calories, making it a very lean protein.

  • Rich in Protein: It is a high-protein source, with 3 ounces providing approximately 25 grams of protein.

  • Cooking Method is Key: Deep-frying octopus drastically increases its calorie and fat content, while boiling or grilling keeps it lean.

  • Packed with Nutrients: Octopus is rich in essential vitamins and minerals, including B12, selenium, iron, and omega-3 fatty acids.

  • Supports Weight Management: The high protein-to-calorie ratio helps with satiety, making it a filling food for calorie-controlled diets.

Is Octopus a High-Calorie Food?

Contrary to what some might assume about seafood, a basic, moist-heat cooked octopus is not high in calories. The caloric content is quite low, and the bulk of its energy comes from protein, not fat or carbohydrates. For instance, a 3-ounce (85-gram) portion of cooked octopus contains about 139 calories, 25 grams of protein, and only 2 grams of fat. This makes it a great choice for those focused on weight management, muscle building, or simply incorporating leaner protein sources into their meals.

The Nutritional Breakdown of Octopus

Beyond its low-calorie status, octopus is a powerhouse of micronutrients that are crucial for overall health. It is exceptionally rich in Vitamin B12, which is vital for nerve function and red blood cell production. It also contains high levels of selenium, a potent antioxidant that supports thyroid function and the immune system. The mineral iron, essential for oxygen transport, is also found in significant amounts.

  • Vitamin B12: A single serving of octopus can provide well over the daily recommended intake of this important vitamin.
  • Selenium: A key mineral for antioxidant defense and supporting metabolism.
  • Iron: Supports energy levels and fights anemia.
  • Omega-3 Fatty Acids: Contains heart-healthy omega-3s, which help reduce inflammation.
  • Taurine: An amino acid with antioxidant properties.

How Cooking Method Affects Octopus Calories

While the octopus itself is naturally low in calories, the cooking method can drastically change its overall nutritional impact. A boiled or grilled octopus will retain its lean nutritional profile, but frying it will absorb a significant amount of oil, dramatically increasing its calorie and fat content. It is essential to be mindful of preparation techniques when including this seafood in a calorie-controlled diet.

Common Cooking Methods and Their Calorie Impact:

  • Boiling/Steaming: Adds no significant extra calories. This is the best method to preserve the natural, lean nutritional value.
  • Grilling: Similar to boiling, grilling adds minimal extra calories, especially when using a small amount of olive oil.
  • Deep-Frying (Calamari): Batter and oil significantly increase calories and fat. Frying can easily double or triple the final calorie count.
  • Canned in Oil: Octopus canned in oil will have higher fat and calorie content compared to fresh or water-packed versions.

Octopus vs. Other Popular Proteins: A Nutritional Comparison

To put the calorie count of octopus in perspective, a comparison with other common protein sources highlights its benefits. Octopus provides a high protein-to-calorie ratio, making it an excellent choice for those seeking to feel full on fewer calories.

Food Item (3 oz / 85g Serving) Calories Protein (g) Fat (g)
Cooked Octopus ~139 ~25 ~2
Cooked Chicken Breast ~140 ~26 ~3
Cooked Beef (lean) ~170 ~24 ~8
Cooked Salmon ~180 ~22 ~9
Fried Calamari (estimate) ~200+ ~18 ~10+

Note: Nutritional values are approximate and can vary based on preparation and portion size.

As the table shows, octopus offers a protein and calorie profile very similar to skinless chicken breast, positioning it as a top contender for lean protein consumption. The comparison also starkly illustrates the difference between simply cooking octopus versus deep-frying, as with calamari, which dramatically raises the fat and calorie levels.

Conclusion: A Low-Calorie, Nutrient-Dense Option

In conclusion, the question of "does octopus have high calories?" can be confidently answered with a resounding no, provided it is prepared using healthy cooking methods. This lean seafood is an exceptional source of high-quality protein and essential micronutrients like vitamin B12, selenium, and iron, all with a low-calorie impact. Whether boiled, grilled, or steamed, octopus serves as a delicious and nutritious option for anyone looking to maintain a balanced diet, control their weight, or simply enjoy a different kind of seafood.

Frequently Asked Questions

Yes, octopus is beneficial for weight loss due to its high protein and low-calorie content. The protein helps you feel full, reducing overall calorie intake, especially when prepared by boiling, steaming, or grilling.

A cooked octopus serving has a very similar calorie and protein profile to a cooked skinless chicken breast. Both are excellent sources of lean protein.

Deep-frying octopus adds a significant amount of oil and batter, which dramatically increases its calorie and fat content, negating its natural lean profile.

Octopus is rich in several vitamins, most notably Vitamin B12. It also contains good amounts of Vitamin B6 and other micronutrients.

No, octopus is very low in fat. A 3-ounce serving contains only about 2 grams of fat. However, this can change depending on the cooking method and added ingredients.

Calamari, which is typically fried squid, is significantly higher in calories than cooked octopus due to the preparation method involving batter and deep-frying. A grilled or boiled squid would have a lower calorie count.
