While all salmon is a healthy source of protein and omega-3 fatty acids, there is significant variation in calorie and fat content across different species and farming methods. For those focused on calorie reduction, the leaner, wild-caught Pacific species are the clear winners. Pink and chum salmon are notably the lightest in calories, often a surprise to those accustomed to the richer flavor of fattier varieties like King or Sockeye.
The Top Contenders for Lowest Calorie Salmon
Pink Salmon (Humpback)
Pink salmon is the most abundant and smallest of the Pacific salmon species, and its name comes from its characteristically light, rosy-pink flesh. Its mild flavor and delicate texture are a direct result of its very low fat content. This makes it one of the most calorie-efficient salmon options available. Pink salmon is most frequently sold in cans or pouches, making it an accessible and affordable option for a quick, healthy meal.
Chum Salmon (Keta)
Also known as Keta or dog salmon, chum is another exceptionally lean Pacific species with a lower fat content than other wild-caught salmon. Its flesh is pale to medium-red with a firm, large flake, and a delicate flavor. Because of its mild profile and firmness, it is often smoked or canned, and its roe is highly prized for sushi. Its low calorie density is a key feature for those monitoring their intake closely.
Coho Salmon (Silver)
Sitting in the middle of the calorie spectrum is wild Coho salmon, or silver salmon. It has a milder taste and medium fat content compared to leaner chum and fattier king salmon. Coho's versatility in cooking, paired with its balanced flavor and nutritional profile, makes it a popular choice for many home cooks.
Wild vs. Farmed: A Major Difference in Calories
Beyond species, the biggest factor influencing salmon's calorie count is whether it was raised in the wild or on a farm. This is due to a fundamental difference in diet and exercise.
- Wild-caught salmon are free to roam and forage on a natural diet, which results in leaner, more muscular fish.
- Farmed salmon are raised in confined pens and fed a processed, high-fat diet to increase growth and size, leading to a much higher fat percentage and calorie count.
For example, a 100-gram serving of cooked farmed Atlantic salmon contains roughly 206 calories, while the same amount of cooked wild Pacific salmon contains about 182 calories. The wild variety has significantly less fat, particularly saturated fat. It is important to note that all commercially sold Atlantic salmon is farmed, as the wild population is endangered.
Comparison Table: Calories and Fat by Salmon Type
| Salmon Type | Habitat | Avg. Calories (per 3.5oz/100g, cooked) | Avg. Fat (per 3.5oz/100g, cooked) | Key Characteristics | 
|---|---|---|---|---|
| Pink Salmon | Wild Pacific | ~120-130 kcal | ~4g | Leanest, mild flavor, most often canned | 
| Chum Salmon | Wild Pacific | ~120-125 kcal | ~4g | Very lean, firm flesh, delicate flavor | 
| Coho Salmon | Wild Pacific | ~145-150 kcal | ~7-8g | Medium fat content, mild flavor | 
| Sockeye Salmon | Wild Pacific | ~150-155 kcal | ~6g | Leaner, bright red flesh, bolder flavor | 
| King Salmon | Wild Pacific | ~170-180 kcal | ~10-11g | Highest fat, rich flavor, buttery texture | 
| Atlantic Salmon | Farmed | ~205-210 kcal | ~12-15g | Highest calories, high fat content | 
Note: Calorie and fat counts can vary based on the specific cut, cooking method, and brand.
Cooking Methods Matter
How you prepare your salmon can also drastically impact its final calorie count. For weight management, methods that don't add extra fat are best.
- Baking, poaching, or steaming: These methods rely on moisture to cook the fish, avoiding the need for additional oils or butter. This keeps the calorie count of even a fattier salmon lower.
- Grilling: While grilling can be a healthy option, adding oils to the fish and grill can increase the calorie content.
- Pan-frying: This method, when done with minimal oil, can be a good way to get crispy skin without adding too many extra calories.
The Leanest Option and Why it's a Smart Choice
If your primary goal is to consume the lowest calorie salmon, wild-caught pink or chum varieties are your best bet. Not only are they naturally leaner, but they are also a sustainable and affordable choice. While they are lower in omega-3s compared to fattier varieties like King or farmed Atlantic, they still provide a healthy amount of these essential fatty acids. When buying fresh, ensure you are not overcooking these leaner types, as they can dry out more easily than their fattier counterparts. The convenience of canned pink or chum salmon also makes it a simple addition to salads, bowls, or sandwiches for a quick, low-calorie protein boost.
Conclusion
For those seeking the lowest calorie salmon, wild-caught Pacific species, specifically pink and chum, are the ideal choice due to their naturally leaner profile. The contrast between wild and farmed salmon is significant, with farmed varieties having a considerably higher fat and calorie count. By choosing leaner species and healthy cooking methods like baking or steaming, you can maximize the nutritional benefits of this popular seafood while staying mindful of your calorie intake.
