Quick Answer: No, fresh or desalted cod does not cause weight gain on its own. It provides about 80-105 kcal per 100g cooked, 18-20g of protein, and less than 1g of fat. What adds calories is the preparation method: breading, frying, or fatty sauces. When baked or steamed, it is one of the most recommended fish for weight loss.
What does science say about cod and weight?
Cod (Gadus morhua) is one of the most studied white fish in clinical nutrition. The evidence is quite clear: diets rich in white fish are associated with a lower risk of overweight and a better cardiovascular profile, according to EFSA reviews and guidelines from the Spanish Society of Community Nutrition (SENC).
Cod stands out for its low caloric density (kcal per gram) combined with high complete protein. This translates into greater satiety per calorie than practically any lean meat. A study published in Nutrition Research (Vikøren et al., 2013) showed that including cod 5 times a week in low-calorie diets improved body composition compared to equivalent diets without white fish.
Scientific conclusion: cod does not cause weight gain; it helps with weight loss when it replaces fattier protein sources.
Cod Calories and Macros (Nutritional Table)
These are the approximate values per 100g according to BEDCA and USDA FoodData Central:
| Type of cod | Calories | Protein | Fat | Carbohydrates |
|---|---|---|---|---|
| Fresh raw cod | 80-82 kcal | 17-18 g | 0.6-0.9 g | 0 g |
| Desalted cod | 90-105 kcal | 20-22 g | 0.7-1 g | 0 g |
| Dry-salted cod | 280-300 kcal | 63-75 g | 2-3 g | 0 g |
| Baked cod (no oil) | 95-110 kcal | 20-22 g | 0.9-1.2 g | 0 g |
| Battered and fried cod | 220-280 kcal | 14-17 g | 12-18 g | 8-12 g |
Nutritional values are approximate ranges according to BEDCA (Spanish Food Composition Database) and USDA FoodData Central. The exact figure varies by origin, cut, preservation, and preparation method.
Key data: desalted cod cooked healthily is around 100 kcal per 100g. A generous portion of 200g provides about 200 kcal and over 40g of protein, almost half of an adult's daily requirement.
Does cod make you gain weight? The honest answer
The short answer: no, cod does not make you gain weight. The long answer depends on how you cook it.
- Baked, steamed, grilled, or en papillote cod: 95-130 kcal per 100g. Suitable for any weight loss diet.
- Cod in salad (esqueixada, xató): 120-160 kcal per 100g. Excellent summer option.
- Cod fritters or battered: 220-300 kcal per 100g. Beware: oil triples the calories.
- Cod 'al pil-pil' or with béchamel: 250-350 kcal per 100g. A celebratory dish, not for daily consumption.
The trick is to mentally separate the fish from the cooking method. Raw cod is one of the foods with the best protein/calorie ratio on the market. What you add to it determines whether it causes weight gain or not.

Some practical guidelines for those who want to lose weight or maintain it without sacrificing flavor:
- 2-3 servings per week of white fish (SENC recommendation). Cod fits perfectly into this pattern.
- 150-200g raw servings: provide 30-40g of protein, enough to satisfy a meal without excessive calories.
- Accompany with plenty of vegetables: spinach, baked peppers, green salad. Fiber prolongs satiety.
- Whole grains in moderation: 60-80g of raw brown rice or quinoa.
- Controlled good fats: one tablespoon (10ml) of extra virgin olive oil at the end.
A typical dish "baked cod + steamed vegetables + 60g quinoa + EVOO" is around 400-450 kcal. Satisfying, balanced, high in protein.

- "Salted cod makes you gain more weight": false. It provides sodium, not more calories per gram of protein. If you are concerned about sodium, desalt it properly (48h with water changes).
- "It's more fattening at night": false. The time of day does not change thermogenesis. Eating grilled cod for dinner is one of the best nighttime options.
- "Canned cod in oil is light": depends. Well-drained, it provides about 150-180 kcal per 100g, neither light nor heavy.
- "Cod has a lot of cholesterol": no. It has 50-55 mg per 100g, less than an egg (≈ 200 mg).
