Brussels in July and August is a different city from the rest of the year. The terrasses fill up, everyone is outside, the barbecues appear on apartment balconies and in parks, and the pace slows down enough that eating feels more social than mechanical. Most of this is fine for keto. Some of it is genuinely easy. One part of it is a problem.
Barbecues
The barbecue is one of the best social situations you can be in on keto. Grilled meat, some kind of salad, maybe some grilled vegetables — this is the format. Belgian barbecues tend toward sausages, chicken thighs, merguez, lamb chops, and various cuts of pork, all of which are good. The salads are usually dressed in something reasonable. The one thing to watch is the marinades on chicken or pork, which sometimes contain honey or sweet sauces — either ask or scrape most of it off before eating.
Nobody at a Belgian barbecue will question why you’re not eating the baguette. The meat is clearly the point.
Terrasses and cold drinks
Sitting outside with something cold in your hand is one of the genuine pleasures of a Brussels summer, and the drink situation is where the friction is. Belgian beer is everywhere, it’s cold, it’s what people are drinking, and it’s what you are not drinking. Dry white wine is easy to find at most terrasse bars. A gin and tonic works. Sparkling water with lemon is a reasonable order that doesn’t attract commentary.
The cidre situation at some places is an alternative that looks appealing — most Belgian cidre is quite sweet and has significant carbs, so check before assuming.
The ice cream problem
This is the actual difficult part. Belgium takes ice cream seriously and the glacier shops in Brussels — particularly around Ixelles, Châtelain, and the city centre — are good. Standing outside a good glacier in August while everyone around you is eating artisanal pistachio ice cream is a specific kind of difficulty that is hard to plan around.
There isn’t a great solution here. Sorbet is worse than ice cream for carbs, not better. Low-carb ice cream alternatives exist but aren’t available at most Brussels glaciers. You’re essentially deciding whether to have one occasionally and accept the consequences, or to skip it entirely and feel briefly sorry for yourself on warm evenings.
Practical summer notes
The fresh vegetables available in summer — courgettes, aubergines, peppers, tomatoes — make cooking at home easier and better than in winter. The markets have more variety. The salads at restaurants are actually good when the ingredients are seasonal.
The longer days mean more eating occasions — a long Sunday in a park involves multiple food decisions across a day rather than two scheduled meals. Planning ahead slightly, whether that means bringing food or knowing which places to stop at, matters more than in winter.
Summer in Brussels is genuinely good. The keto angle makes the drinks and the ice cream harder, and that’s about it.
