In short. The lighter version (per serving: one plate) comes to about 526 kcal with 44 g of protein and 12 g of fat, against about 1016 kcal, 34 g and 50 g for the classic. That is 490 fewer kcal, 10 g more protein and 38 g less fat. Figures are fitness estimates built from USDA FoodData Central entries.
Food photographs are illustrative; they do not show the exact lighter recipes or portions used for the nutrition figures below.
Why the classic is heavy
Cod is about 82 kcal per 100 g raw, and nearly all protein. Batter and frying oil turn it into a plate that is mostly coating, and the fries soak up more oil.
The swaps, per serving
Restaurant fish and chips: 200 g of battered fried fish fillet and 200 g of restaurant-style fries.
Baked cod and oven chips: 180 g of raw cod, 15 g of breadcrumbs, egg white, 220 g of russet potato baked with 6 g of olive oil, and 60 g of peas.
| Per serving | Classic | Lighter | Change |
|---|---|---|---|
| kcal | 1016 | 526 | −490 |
| Protein g | 34 | 44 | +10 |
| Carbs g | 108 | 59 | −49 |
| Fat g | 50 | 12 | −38 |
Weights are raw for meat, fish, eggs and vegetables, and cooked for pasta and rice. Fat that cooks out into the pan is not subtracted from either version, and brands and portions change real numbers. These are fitness estimates, not medical or dietary advice.
1. Bake cod in a thin crumb
Dip in egg white and press into breadcrumbs. A hot oven crisps the crust.
2. Oven chips
Cut potatoes thick, dry them very well, toss with a little olive oil and bake hot, turning once.
3. Peas on the side
Peas bring protein, fibre and colour.
4. Lemon and a yogurt tartare
Mix Greek yogurt with chopped pickles, capers and lemon.
How to make it
- Toss the wedges in olive oil and roast them first.
- Dip the cod in egg white and then in crumbs.
- Bake the fish on a rack for the last 12 to 15 minutes.
- Serve with peas, lemon and the tartare.
Log it so the numbers hold
Weigh the fish raw. Cooking changes the weight, and raw is the repeatable number. In One Fitness Hub, Create a recipe in Add food takes the ingredients by weight and the number of servings, then saves the dish as one of your own foods for next time.
Quick answers
- Does baked fish go dry? Cod is lean. Stop when it flakes, and do not overbake.
- Can I use frozen fish? Yes. Thaw and pat dry.
- Is battered fish worse? Batter and frying oil add fat and calories. That is the swap.
- Where do the numbers come from? Each ingredient is a USDA FoodData Central entry, the same library the app searches.
