A 140g salmon fillet contains 290 kcal and is free on Slimming World when baked, poached, or grilled without added fat. Smoked salmon is 66 kcal per 50g serving — the lowest calorie salmon format by portion size, and also free on SW.
Salmon is higher in calories than white fish like cod (95 kcal per 100g) because of its fat content — but most of that fat is omega-3, which is why salmon is treated as a healthy option despite the higher calorie count. On Slimming World, all plain salmon is free regardless of the fat content.
This guide covers calories for every salmon format — fresh fillets, smoked salmon, tinned salmon, and fish fingers — with Slimming World syn values and WW SmartPoints.
Fresh salmon contains approximately 208 kcal per 100g. A standard 140g supermarket salmon fillet contains 291 kcal. Smoked salmon contains 142 kcal per 100g — lower because it is sliced thin and served in smaller portions. Tinned salmon in brine is around 128 kcal per 100g drained.
| Salmon format | Portion | Calories | Protein | SW Syns |
|---|---|---|---|---|
| Fresh salmon fillet (baked/grilled) | 140g | 291 kcal | 28g | Free |
| Fresh salmon fillet (poached) | 140g | 280 kcal | 27g | Free |
| Smoked salmon | 50g | 71 kcal | 10g | Free |
| Tinned salmon in brine (drained) | 105g tin | 134 kcal | 25g | Free |
| Tinned salmon in sunflower oil (drained) | 105g tin | 175 kcal | 22g | Free |
| Salmon en croute (supermarket) | ~200g | 480 kcal | 22g | 14 |
| Salmon fishcakes (supermarket, 2) | ~200g | 330 kcal | 18g | 8 |
| Birds Eye salmon fish fingers (4) | ~128g | 254 kcal | 14g | 6 |
Salmon en croute is the highest calorie salmon product at 480 kcal per serving — the pastry case adds around 200 kcal on top of the salmon fillet itself. All plain salmon cooked without added fat or pastry is free on Slimming World.
Yes — fresh, smoked, tinned, and frozen salmon fillets are all free on Slimming World when cooked without added fat. Salmon in brine, spring water, or tomato sauce is free. Salmon in oil is also free — the oil is the storage medium and the syn calculation applies to the fish itself, not the packing liquid.
Processed salmon products — fishcakes, fish fingers, salmon en croute, smoked salmon pâté — are not free because of the added ingredients (breadcrumbs, pastry, cream cheese). All plain salmon in any straightforward cooking format is free.
Smoked salmon contains 142 kcal per 100g and approximately 71 kcal per standard 50g serving. A typical supermarket packet of smoked salmon contains 100–120g total — around 142–170 kcal for the whole packet and completely free on Slimming World.
Smoked salmon is one of the best value foods on plan for a satisfying light meal. A 100g pack with scrambled eggs (two large eggs, 156 kcal) and a toasted wholemeal muffin (HEB, free) is a complete 450 kcal breakfast for 0 syns. Most ready-made smoked salmon lunches from supermarket meal deal shelves cost significantly more in both money and calories for a less filling result.
Tinned salmon in brine contains approximately 128 kcal per 100g drained — very similar to tinned tuna (116 kcal per 100g in brine). A standard 105g tin drained is around 134 kcal and free on Slimming World. Tinned salmon in sunflower oil drained is around 167 kcal per 100g.
Tinned salmon is a useful cheaper alternative to fresh for midweek meals — salmon pasta, salmon fishcakes made at home, and salmon and potato bakes all work well with tinned rather than fresh. The omega-3 content of tinned salmon is comparable to fresh, making it a genuinely equivalent nutritional choice at a fraction of the price.
Salmon supports weight loss through high protein and omega-3 content — both of which reduce appetite and improve satiety. Research published in Appetite (2008) found that fish-based meals produced significantly greater satiety than beef-based meals of identical calorie content, with participants consuming 11% fewer calories at the following meal.
On a practical level, a 140g salmon fillet at 291 kcal provides 28g protein — comparable to chicken breast but with substantially more omega-3. The combination of protein and fat in salmon creates a strong satiety response. Members who struggle with hunger on plan often find swapping chicken for salmon two or three times a week reduces between-meal snacking.
Tinned tuna in brine contains 116 kcal per 100g — lower than tinned salmon at 128 kcal per 100g. Fresh tuna steak is 103 kcal per 100g versus 208 kcal per 100g for fresh salmon. Tuna is the lower calorie fish for fresh and tinned formats.
Both are free on Slimming World. The calorie difference is meaningful if you are counting closely — a 140g tuna steak is around 144 kcal versus 291 kcal for a salmon fillet. Tuna wins on calories; salmon wins on omega-3 content. For weight loss purposes both are excellent choices and the decision can be made on taste and price rather than calorie optimisation.
