Ask people what surprised them most about keto and a lot of them will skip past weight and talk about their head. Steadier focus, fewer energy crashes, and a working afternoon that no longer falls apart around three o’clock. Plenty find this. Some notice nothing. A smaller group feel distinctly worse for a while before anything improves. All three experiences are normal, and it helps to understand why before you decide which one applies to you.
If you start keto and keep training, the first few weeks will feel like a downgrade. Your usual run drags, your normal weights feel borrowed from someone stronger, and you finish sessions wondering whether you have broken something. You have not. What you are feeling is your body rewiring its fuel system, and the slump is temporary. Knowing roughly how it unfolds, and why, is what stops people quitting in week two when they were three weeks from feeling fine.
Sticking to keto and still wanting a drink are not mutually exclusive, but they do require a bit of planning. Some drinks barely register on your carb count, while others will spend your entire day’s budget in a single glass. And beyond the carbs themselves, alcohol does a few things to a fat-adapted body that are worth understanding before you order. Living in a place like Brussels, where beer is practically a civic institution, sharpens the question further.
Brussels is a surprisingly good city for eating keto, with one obvious problem: frites come with everything. Once you make peace with asking for a salad instead, you’re mostly fine.

Brasseries are your friend The classic Brussels brasserie is built for keto without knowing it.
Keto gets explained in two unhelpful ways: either as a miracle that melts fat while you sleep, or as a joyless slab of bacon and butter. Neither is right. When I first looked into it, most of what I found sat at one of those two extremes, and neither matched living it. The ketogenic diet is a fairly simple metabolic idea with some real evidence behind it and a few genuine catches, and once you understand the mechanism the rest of it stops feeling like a list of arbitrary rules.
