Japanese Bento Meal Prep: Balanced Boxes Under 600 Calories

Japanese nutritionists recommend the 3:1:2 ratio for a balanced bento:

• 3 parts grain (rice, noodles) — about half the box
• 1 part protein (meat, fish, egg, tofu) — about 1/6 of the box
• 2 parts vegetables (sides, pickles, salad) — about 1/3 of the box

A standard 600ml bento box following this ratio comes out to roughly 500-600 calories — perfect for a working lunch.

• White rice with umeboshi — 250 kcal
• Grilled salmon fillet — 150 kcal
• Tamagoyaki (2 slices) — 60 kcal
• Kinpira gobo (burdock root) — 40 kcal
• Broccoli with sesame — 20 kcal

• White rice with furikake — 260 kcal
• Karaage (3 pieces) — 200 kcal
• Potato salad (small) — 60 kcal
• Cherry tomatoes — 10 kcal
• Pickled cucumber — 5 kcal

• Brown rice — 220 kcal
• Tofu steak with teriyaki — 100 kcal
• Hijiki nimono (seaweed salad) — 40 kcal
• Ohitashi (spinach) — 25 kcal
• Pickled daikon — 10 kcal

Great for vegetarians and anyone doing a lighter day.

• Use a smaller box — 500ml = ~450 kcal, 600ml = ~550 kcal, 700ml = ~650 kcal
• Log your bento in BentoCalorie — snap a photo of your box before eating
• Prep on Sunday — cook rice, proteins, and 2-3 sides for the whole week
• Freeze onigiri — wrap in plastic, microwave for 90 seconds in the morning
