The Meal Prep Math That Actually Works
Skip the Instagram tupperware aesthetic. Real meal prep is three numbers: your daily calorie floor, your protein target, and the grams you need per container.
Most meal prep fails on Wednesday, not Sunday. You cooked five identical containers, you are already bored, and the leftovers rot. The reason is that people prep by recipe, not by number.
Prep by number and the whole thing gets easier. You cook the same core ingredients, then vary the sauces and seasonings across the week. Same math, different food — which is exactly how restaurants stretch four base ingredients into ten dishes.
Step 1: pick your daily target
Start with a rough calorie floor — for many adults that is 1800 to 2400 kcal — and a protein target of about 1.8 g per kg of body weight. Divide the calories by the number of meals you plan to prep. That is your per-container calorie budget.
For a 70 kg adult eating four meals: about 500 kcal and 32 g of protein per container. Every prep decision downstream is arithmetic against those two numbers.
Step 2: build one plate, weigh once
In Procaaf, drag your ingredients in and adjust grams until the total hits your per-container target. Save that plate. That is your template — the calorie and protein maths are done for the whole week.
The weighing matters exactly once. After that, you scoop by eye against the same containers and the numbers stay within a rounding error.
Step 3: rotate protein and vegetables
Same rice, same lentil quantity, same olive oil. Swap the protein (chicken → tofu → salmon → eggs) and the vegetable (broccoli → peppers → zucchini → spinach) across the week. Change the seasoning: soy-ginger on Monday, harissa on Tuesday, lemon-oregano on Wednesday. The macros barely move; your taste buds think it is a different meal.
Step 4: prep only what survives the fridge
Some foods hold up for four days in the fridge (grains, cooked legumes, roasted root vegetables, chicken thighs). Others fall apart in two (fish, leafy greens, avocado). Prep the durable stuff in bulk on Sunday. Add the fragile stuff the night before you eat it.
That single split — durable versus fragile — is the difference between meal prep that works and meal prep that ends with a sad container in the bin.
