Meal planning for busy office workers

Most meal plans online assume you can cook and have time. Grilling chicken breast in the morning and packing a lunch box is a great plan — but if you leave for work at 7 and get home at 9, you can’t even start it.

This guide starts from these conditions: you can barely cook, lunch is eaten out, and dinner is delivery or something simple.

Principle 1. Start with what you can control

Trying to manage all three meals usually fails. Instead, separate the meals you fully control from the ones that depend on circumstances.

Just getting breakfast and snacks right covers half your day, because those two aren’t affected by anyone else’s plans.

Principle 2. Use protein as your baseline

Counting calories every time doesn’t last. Instead, just checking “is there protein in every meal?” solves most problems. Getting enough protein naturally makes you fuller, and total intake often drops as a result.

• Aim for 1.2–1.6 g per 1 kg of body weight (84–112 g at 70 kg)
• Divided by your meals, that’s 25–35 g per meal
• A Korean-style lunch rarely gets above 20 g, so make it up at breakfast and snacks

Principle 3. Balance it out over the week

Days with a work dinner or a late meal after overtime won’t go to plan. Judge success day by day and one bad day leads to giving up the next day too.

If 5 out of 7 days go to plan, that’s enough. The key is to keep lunch a bit lighter on work-dinner days — and not to try to make up for it by starving the next day.

A sample day

Here’s an example for a 32-year-old man (82 kg, losing weight, about 1,900 kcal a day) who barely cooks.

That’s about 1,695 kcal and 105 g of protein in total. Not one meal was cooked, and lunch and dinner are what he usually eats. The only changes: he added breakfast and cut his rice by 1/3.

Handling common situations

These situations come up again and again at work. Each is covered in more detail in related guides.

• When it’s hard to choose lunch — make Korean set meals your default and just adjust the rice
• When you grab something at a convenience store — choose by 20 g of protein rather than calories
• When you order delivery — dropping the side menu alone cuts 300–500 kcal
• The day after a work dinner — don’t starve; eat as usual, just skip the late-night snack

Where to start

1. Week 1 — pick one breakfast and eat the same thing every day
2. Week 2 — try leaving 1/3 of your rice at lunch
3. Week 3 — prepare an afternoon snack in advance
4. Week 4 — set how many times a week you’ll order delivery

Try to change all four at once and you’ll usually be back where you started within 2 weeks. Moving on once each one becomes a habit ends up being faster.
