Portion & nutrition guidelines

Aim for 3–5 oz cooked fish per meal (about palm-sized).
Include 2+ servings of vegetables and 1–2 servings of whole grains or starchy veg daily.
Keep added fats modest: 1 tbsp olive oil per cooking or dressing serving.
Target 20–30 g protein per main meal; total calories ~1,400–1,800 depending on activity.
Swap higher-calorie fish (e.g., mackerel) for leaner options (cod, tilapia) to reduce calories; include oily fish 1–2×/week for omega-3s.

Cooking & flavoring tips

Use baking, steaming, grilling, or poaching to minimize added fat.
Brighten with citrus, fresh herbs, capers, or low-sodium soy/miso instead of heavy sauces.
Use spice rubs and smoking for variety without extra calories.
Quick cooking: thin fillets cook in 3–6 minutes per side; thicker fillets need 8–12 minutes depending on method.

Shopping & storage

Buy fresh fish from reputable sources or opt for frozen fillets (flash-frozen retains quality).
Check for firm texture, mild smell; for frozen, avoid freezer burn.
Store fresh fish ≤2 days in fridge; freeze for longer-term (up to 3 months for best quality).

Health considerations

Watch mercury: limit high-mercury species (tilefish, shark, swordfish, king mackerel) — prefer smaller fish or limit servings for pregnant people and children.
If calorie loss is undesirable, increase portions of whole grains, add healthy fats (nuts, olive oil), or include an extra snack.
Consult a healthcare provider for individualized needs, especially with medical conditions.

Quick weekly prep plan

Buy a mix of lean and oily fillets (4–6 portions each) + frozen veggies/grains.
Batch-cook quinoa/brown rice and roast a tray of mixed vegetables.
Portion single-serving fillets and marinate 1–2 ways for variety; freeze extras.
Pre-chop salad ingredients and store dressings separately.

If you want, I can tailor the plan to a specific calorie target, dietary restrictions, or preferred fish types.
