Targets are planning guides — weigh cooked protein on a scale if you track macros tightly. Sauces and oils add calories not shown here.
How to read the numbers
Meal prep works best when every container is built the same way. The protein line is cooked weight on your scale after resting. Starch lines use dry rice or dry pasta — cook the whole pot, then divide evenly. Vegetables are raw chop volume; roasted veg shrinks, so mound greens a little higher if you reheat all week.
Example per-container targets
| Scenario | About |
|---|---|
| 5 weekday lunches, standard, rice | ≈ 4.5 oz cooked protein + ½ cup dry rice each |
| 10 containers, high protein, low carb | ≈ 5.5 oz cooked protein + extra veg each |
| 8 dinners, hearty, pasta base | ≈ 6 oz cooked protein + 3 oz dry pasta each |

FAQ
- How much protein goes in one meal-prep container?
- A common cooked target is about 4–5 ounces of lean protein for a standard lunch, or 3–4 ounces for lighter deskside portions. This calculator scales by appetite and whether you want a high-protein or lower-carb plate.
- Should I weigh food raw or cooked for meal prep?
- Buy and log raw weight at the store, then portion after cooking when juices have settled. The shopping total here uses a typical ~75% yield for batch-cooked chicken or beef.
- What size meal-prep container do I need?
- Light lunches often fit 2-cup (16 oz) containers. Standard bowls with rice and vegetables usually need 3-cup (24 oz) containers so lids close without crushing greens.
- How is this different from the weekly meal prep estimator?
- This tool sizes one identical container and a single batch. The weekly estimator multiplies people × days × meals for a full shopping list and prep-time ballpark.
