You don’t need a specialty health food shop to do keto in Belgium. Everything essential is available at a standard Belgian supermarket — Delhaize, Colruyt, Carrefour, Lidl, Aldi. This is genuinely useful information because there’s a tendency in keto circles to make the shopping sound complicated, and it isn’t.
What every Belgian supermarket does well
Eggs are the foundation and they’re everywhere. The standard eggs at Colruyt or Aldi are fine. Delhaize carries a better range including free-range and organic options at reasonable prices. Buy them in bulk — if you’re eating keto, you’ll go through them faster than you expect.
Cheese is covered in detail elsewhere on this site but every Belgian supermarket has a decent cheese counter. The pre-packaged options are more limited, but the counter section at most larger Delhaize and Carrefour stores is good enough for everyday eating.
Cold cuts and charcuterie — jambon cuit, jambon d’Ardenne, salami, chorizo — are available everywhere. Check labels on anything that looks heavily processed, particularly the pre-sliced meat in plastic trays, which sometimes contains added sugars and starches. The counter section is generally cleaner than the pre-packaged stuff.
Nuts: almonds, walnuts, and macadamias are all at Belgian supermarkets. Lidl and Aldi have good prices on nuts. Avoid the flavoured and coated varieties.
Dark chocolate at 70% or higher is a reasonable keto snack and every Belgian supermarket sells it. Côte d’Or 70% is the one you’ll see most often. Lindt 85% is available at most chains. Lidl’s own-brand dark chocolate is good value.
Full-fat Greek yoghurt: Delhaize and Colruyt both stock it. Look for the label — it should say full-fat and have no added sugar. FAGE is the brand most commonly available. Avoid the flavoured varieties.
What the Belgian supermarkets don’t do as well
Specialty fats like coconut oil and MCT oil are not reliably stocked at standard supermarkets — you’ll need a health food shop or to order online. Delhaize sometimes carries coconut oil, but not consistently.
Almond flour and other low-carb baking ingredients are hit or miss. The larger Delhaize Bio sections carry some of this but the selection is limited. If you bake on keto, ordering online or going to an organic shop is more reliable.
Electrolyte products and specific keto supplements are generally not in supermarkets — pharmacy or online is the way to go.
The practical reality is that your weekly shop for keto can happen entirely at Colruyt or Delhaize, with a Sunday trip to the Marché du Midi if you want better fish and vegetables. That’s it. No specialist shops required unless you’re trying to do something specific.
