7-Day Meal Prep With a Food Scale: The Exact Plan (With Gram Weights)

Meal prep is one of the highest-leverage habits for anyone trying to eat well consistently. But most meal prep guides skip the single step that makes the difference between a week of on-target eating and a week of "close enough" — weighing your food.

AI Smart Food Scale – Precise nutrition tracking at 1g increments

This 7-day meal prep plan is built around a food scale. Every portion is defined in grams. Every meal has clear macro targets. And the prep itself is designed to take 90 minutes on Sunday — leaving you with seven days of lunches and dinners that require no tracking, no decisions, and no guesswork.

Why Weighing Makes Meal Prep Actually Work

Standard meal prep recipes say things like "1 cup of rice" or "a medium chicken breast." The problem:

These differences compound across 7 days. Without a scale, you might be eating 300–400 more or fewer calories per day than you think — enough to stall weight loss or leave you underfueled for workouts.

With a scale, each container is identical. You weigh once, fill all containers, and every meal for the week is accurate. No re-tracking required.

What You Need Before You Start

Equipment

  • A food scale (1g precision — the EverMetric AI Smart Food Scale shows nutritional data as you weigh, making the process even faster)
  • 7–10 airtight meal prep containers (roughly 2–3 cup capacity)
  • A large sheet pan and a pot
  • A cutting board and knife

Your Macro Targets

Before cooking, set a target for each meal. A common fat-loss target for a moderately active adult:

  • Protein: 35–40g per meal
  • Carbs: 40–60g per meal
  • Fat: 10–15g per meal
  • Calories: ~400–550 per meal

Adjust to your specific calorie needs. Use a TDEE calculator to find your maintenance calories, then subtract 300–500 calories for a fat-loss deficit.

The 7-Day Meal Prep Plan

This plan covers lunch and dinner for 7 days — the two meals where portion control matters most. Breakfast is kept flexible (eggs, Greek yogurt, oats) since it is easier to weigh fresh each morning.

Ingredient Total Amount Per Meal (Lunch) Per Meal (Dinner)
Chicken breast (raw) 1,680g (~3.7 lbs) 120g raw 120g raw
Brown rice (dry) 700g 50g dry —
Sweet potato (raw) 840g — 120g raw
Broccoli (raw) 1,400g 100g 100g
Olive oil 210ml 7ml (1.5 tsp) 8ml (1.5 tsp)
Spinach (raw) 700g 50g 50g

Approximate Macros Per Meal

Meal Protein Carbs Fat Calories
Lunch (chicken + rice + broccoli + spinach) ~38g ~48g ~11g ~450 cal
Dinner (chicken + sweet potato + broccoli + spinach) ~37g ~42g ~11g ~420 cal

Step-by-Step Prep Instructions (90 Minutes)

Minutes 0–10: Set Up and Pre-Weigh

  1. Place all 14 containers on your counter
  2. Place your food scale in the center of your prep area
  3. Tare your scale, then weigh 50g of dry brown rice × 7 portions into a large pot. Add water and cook (20–25 min)
  4. While rice cooks, weigh 120g raw chicken × 14 portions and arrange on sheet pans

Minutes 10–30: Protein Prep

  1. Season chicken with salt, pepper, garlic powder
  2. Roast at 400°F (200°C) for 22–25 minutes until internal temperature reaches 165°F
  3. While chicken cooks, weigh and chop broccoli (100g × 14 portions — cook in batches)
  4. Weigh sweet potatoes: 120g × 7 portions, cube, add to a second sheet pan
  5. Roast sweet potatoes at 400°F for 25–30 minutes

Minutes 30–60: Cook Remaining Ingredients

  1. Steam or roast broccoli portions (10–12 min)
  2. Weigh spinach: 50g × 14 portions (no cooking needed — wilts when mixed with hot food)
  3. Check rice — drain and portion into 7 lunch containers (the rice expands: 50g dry = approx 140–150g cooked)

Minutes 60–90: Assemble and Weigh

This is the most important step — and where your food scale earns its keep.

  1. Lunch containers: Add 50g spinach → place container on scale, tare → add 100g broccoli → tare → add ~90g cooked chicken (equivalent to 120g raw) → tare → drizzle 7ml olive oil → add rice portion
  2. Dinner containers: Same process with sweet potato instead of rice
  3. Seal, label with day of week, and refrigerate (days 1–4) or freeze (days 5–7)

Pro tip: If using an AI food scale, place each ingredient on as you add it to see real-time nutritional totals. You can adjust portions slightly to hit exact calorie targets for each container.

Variation Week: Swapping Proteins and Carbs

The same system works with different protein and carb sources. Use the same weights — just swap the food:

Protein Swap Raw Weight per Meal Approximate Protein
Salmon fillet 130g ~28g protein
Ground turkey (93% lean) 130g ~32g protein
Tofu (extra-firm) 180g ~22g protein
Eggs (whole, large) 3 eggs (~165g) ~18g protein
Canned tuna in water 120g drained ~28g protein
Carb Swap Dry/Raw Weight per Meal Approximate Carbs
White rice 50g dry ~38g carbs
Quinoa 50g dry ~30g carbs
Oats (for breakfast bowls) 50g dry ~30g carbs
Lentils 60g dry ~28g carbs + 12g protein
Potato (white, raw) 150g ~26g carbs

How to Scale This Plan Up or Down

The target of 450 calories per meal works for people aiming for ~1,600–1,800 calories per day. To adjust:

  • Increase calories: Add 20g more dry rice or grain per meal (+70 cal), or increase chicken to 140g raw (+15g protein, +50 cal)
  • Reduce calories: Drop grain to 35g dry per meal, or reduce chicken to 100g raw
  • More fat: Increase olive oil to 12ml per meal (+45 cal, +5g fat)

Because everything is weighed, scaling is exact. A 10% reduction in portion size is a 10% reduction in calories — no estimation required.

Keeping Meals Fresh All Week

  • Days 1–4: Refrigerate. Chicken and rice stay good for 4 days when sealed properly.
  • Days 5–7: Freeze immediately after assembly. Transfer to the fridge the night before you plan to eat them.
  • Reheat: Microwave with a damp paper towel over the top to prevent drying out (2–3 min).
  • Do not pre-dress: Add any wet condiments (hot sauce, lemon juice) just before eating, not during prep — they make vegetables soggy.

Making This a Sustainable Habit

The most common reason meal prep fails is that it feels like too much work. The key insight: it gets faster every week. The first session takes 90 minutes because everything is new. By week 4, it takes 60 minutes. By week 8, it takes 45.

The food scale is the habit anchor. You build muscle memory for portion sizes — 120g of chicken, 50g of rice, 100g of broccoli — until they become automatic reference points. After 6–8 weeks, you can estimate these portions by eye and use the scale only for spot-checks and new foods.
