There is no polite way to say this, so I will just say it: doing keto in Belgium means being at odds with the national drink. Beer here is not a habit, it is a culture. It comes with its own glassware, its own abbeys, its own vocabulary, and a genuine expectation that when you sit down with people, a beer is part of it. When I started keto I was quietly convinced this was the thing that would sink me, not the food but the Friday round, the after-work terrace, the family lunch where an uncle hands you a Tripel before you have taken your coat off.
My first attempt at keto lasted four days. I felt fine on Monday, slightly off on Tuesday, and by Thursday I had a dull headache, legs that felt hollow on the stairs, and the sort of foggy irritability where you snap at people for no reason. I decided the diet did not suit me and went back to bread. It was a full year before I tried again, and the second time I understood what had actually gone wrong.
Nothing about keto is argued over more fiercely than cholesterol, and nowhere is it easier to find confident nonsense from both directions. One camp insists keto wrecks your arteries; the other insists that high cholesterol on keto is completely harmless. The truth is more interesting and more useful than either slogan, and getting it right matters, because for a subset of people this is the one part of keto worth taking seriously.
Spend any time reading about keto and you will meet the phrase “fat-adapted”, usually said with a certain reverence, as though it were a level you unlock. It is a real and useful idea, but it gets muddled with simply being in ketosis, and the timelines people quote are all over the place. Here is a plain account of what fat-adaptation is, how to tell it has happened to you, and why it takes rather longer than the first few days on the diet.
If you have stopped feeling hungry on keto and typed that worry into a search box, the short answer is this: a quieter appetite is one of the most common effects of the diet, and for most people it is a benefit, not a fault. Meals that used to leave you counting the hours to the next snack now hold you until evening. Breakfast starts to feel optional. Some people find they can walk past food they would once have eaten without thinking.
Breakfast and dinner tend to sort themselves out on keto. Lunch is where people come unstuck, because it usually happens away from home, on a short break, near a bakery or a canteen counter stacked with exactly the wrong things. A packed keto lunch removes the daily decision and the daily temptation in one move. The trick is knowing which meals survive a morning in a bag, taste good cold, and leave you steady rather than slumped through the afternoon.
The single most common worry about keto is not whether it works but whether it is safe to keep doing. It is a fair question, and it deserves a better answer than either the cheerleading you get on keto forums or the doom you get in the occasional newspaper headline. The honest picture sits in between, and it depends a great deal on how you do it. Here is what the evidence supports, what it does not, and how to stay on the right side of the line.
Most keto advice assumes one setting: carbs stay low, every day, full stop. For a lot of people that is exactly right and there is no reason to complicate it. But there are two well-established variations that deliberately add carbohydrate back at certain times, and if you train hard or you have hit a wall with strict keto, they are worth understanding. They go by the names targeted keto and the cyclical ketogenic diet, and they are not the same thing.
Sooner or later the question arrives, usually somewhere around a birthday, a holiday or a very persuasive plate of chips. Can you have a cheat meal on keto, and if you do, how much does it set you back? The answers you find online swing between “one bite ruins everything” and “cheat freely, it all balances out”, and neither is true. What actually happens is more interesting and a good deal more manageable once you understand the mechanics.
Most articles about keto talk about what to eat. This one is about something that matters more if it applies to you: what is already in your bathroom cabinet. A ketogenic diet is not a gentle tweak. It changes your blood sugar, your blood pressure, your fluid balance and your metabolism, sometimes within days, and if you take medication for any of those things, the dose that was right for your old way of eating can quickly become too much.
