How to start eating healthier

You don't need a “new life from Monday”. You need a simple plan and one small step. Here are five steps you can take this week.

Information checked on 2026-09-30. General information, not medical advice. How we calculate

In short: 1) find your number, 2) plan a few days, 3) shop once, 4) cook simply, 5) review after two weeks. Add things, don't only take them away. Perfection isn't needed.

First: small, but regular

Some people start too hard: they throw out half the kitchen, start starving and give up after a week. What lasts is what's simple. So on this path every step is small and doesn't have to be perfect. A missed day is just a missed day.

Step 1. Find your number

Your body needs a certain amount of energy. You can work it out with the free calorie calculator or the nutrition quiz. It won't be exact: formulas can be off by about ±10%, so treat it as a starting point and adjust after 2–4 weeks. If you like, you can also work out your protein target.

Step 2. Plan a few days, not a month

In the first week it's enough to plan 3–4 days: two breakfast options and two dinner options, with lunch being yesterday's dinner. You'll find examples on the weekly menus page, and how to build a system in our guide to planning a week of meals.

Step 3. Shop once

  • Write a list from the chosen recipes and check first what you already have at home.
  • Frozen vegetables and fruit are perfectly fine: they keep longer.
  • Don't buy “healthy” foods you've never eaten. Choose things you actually like.

You'll find cheaper choices in our guide to eating healthy on a budget.

Step 4. Cook simply

At the start, choose recipes that take 20–30 minutes or cook themselves in the oven: quick recipes. When you cook dinner, make a double portion, and tomorrow you have lunch. For every main meal a simple (approximate) plate guide helps:

  • half the plate vegetables;
  • about a quarter protein (meat, fish, eggs, curd cheese, pulses);
  • about a quarter starchy food (potatoes, grains, pasta, bread).

Step 5. Review after two weeks

After two weeks, ask yourself a few questions:

  • What worked and what was too hard?
  • Do you feel full and have energy?
  • Are the recipes tasty, or are you tired of the same ones?
  • If you track your weight: what does the weekly average show, rather than one morning?

Change one thing, not everything at once. If your goal is weight loss, read about a safe pace in our guide to the calorie deficit. If counting or weighing starts to make you anxious, see when calorie counting starts to hurt.

When to talk to your doctor first

Before you change how you eat to lose weight, talk to your doctor first if:

  • you are pregnant or breastfeeding;
  • you have diabetes or take medicines that affect your blood sugar;
  • you have kidney disease, heart disease or another long-term condition;
  • you are under 18;
  • you have or have had an eating disorder;
  • you are losing weight without trying.

If your relationship with food worries you, you can talk to a doctor or a psychologist. If you're struggling right now, call your local emergency number or find a free helpline at findahelpline.com.

You can walk this whole path with Dumpli. The nutrition quiz on the website is free. In the app (still in testing) you'll find daily and weekly menus, a shopping list in grams by aisle with tick boxes, and recipes with calories. Take the nutrition quiz → · About the app

Frequently asked questions

Where do I start with eating healthier?

With one small change, not a life overhaul. It's usually easiest to start with what you add: more vegetables, protein at every meal and water. Once that becomes a habit, you can change something else.

Do I have to count calories?

Not always. For a few weeks it can help you see portions, but many people do fine with a ready-made menu and a simple plate guide: half vegetables, a quarter protein, a quarter starchy food. If counting makes you anxious, it's fine to leave it. We wrote about when counting stops helping.

How long does it take to form a habit?

There's no magic number. It depends on the person and the habit, and it's usually weeks or months, not a few days. One skipped or “wrong” meal doesn't undo anything.

How many fruit and vegetables do I need a day?

The World Health Organization recommends at least 400 g of fruit and vegetables a day (about five portions). If you eat less now, don't try to jump to the full amount: add one portion at a time.

Do I have to exercise?

Movement matters for health, but you can start with walks. The WHO recommends 150–300 minutes of moderate activity a week for adults, and it can be built up from a few minutes at a time through the day.
