Fibre is the nutrient people quietly assume they have to give up when they cut carbohydrate, and it is easy to see why. Bread, oats, beans and fruit are the fibre sources most of us grew up hearing about, and nearly all of them are off the keto menu. Yet a well-built ketogenic diet can be a genuinely high-fibre way of eating, sometimes higher than the average carb-heavy plate, because the foods it leans on are mostly vegetables, nuts and seeds.
Somewhere in the first fortnight of keto, a lot of people notice their trips to the bathroom have gone quiet. Constipation is one of the most common early complaints on a low-carb diet, common enough that it is worth expecting rather than panicking about. The good news is that it usually has a handful of ordinary causes, most of them fixable in a day or two once you know what to reach for.
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.
A small set of free tools to take the guesswork out of keto. Everything runs in your browser, nothing is stored, and there is no sign-up. Start with the macro calculator if you are new; the rest are there when you need them.
Getting your numbers Keto Macro Calculator — your daily calories and how much protein, fat and net carbs to eat, from your details and goal. The place to start.
Getting your macros roughly right is most of what makes keto work. Too little protein and you lose muscle; too little fat and you are hungry and miserable; too much carbohydrate and you never reach ketosis. This calculator gives you a sensible starting point in seconds. Enter your details, pick a goal, and it works out your daily calories and the grams of protein, fat and net carbs to aim for.
