Most of the worries about keto are vaguer than people think, but kidney stones are an exception: this is a real, documented risk with a clear mechanism, and it deserves a straight treatment rather than either dismissal or alarm. The good news is that the same understanding that explains the risk also tells you how to avoid it, and for the average person drinking enough water the danger is modest.
A keto weight loss plateau catches almost everyone: a few weeks of satisfying loss, then the scales stop moving, and the worry sets in that the diet has stopped working. Plateaus are normal, usually fixable, and rarely a sign that keto has failed. The trick is to diagnose the stall calmly rather than panic and crash harder, which tends to backfire. Here is how to think about it.

MCT oil turns up in half the keto shopping baskets and most of the online advice, usually with a promise of sharper focus and deeper ketosis attached. It is a genuinely useful fat, but it is also oversold, and using it badly is a fast route to an uncomfortable afternoon. Here is a plain account of what it is, what it does, and how to fit it into keto without wasting money or regretting it an hour later.
People use “keto” and “low carb” as if they were interchangeable, and in casual conversation nobody minds. Nutritionally, though, they describe two different things. Every ketogenic diet is low carb, but plenty of low-carb eating never comes close to ketosis. Knowing where the line sits helps you pick the approach that suits your body and, just as importantly, one you can actually stick to.

If you have keto blood work done, there is a fair chance your thyroid numbers will raise an eyebrow: free T3, the active thyroid hormone, often comes back lower than before. For anyone who has been told low thyroid is bad news, that reads like a warning light. The reality is more interesting, and for most people more reassuring, than the single number suggests. The short version is that a healthy thyroid usually adapts rather than fails on keto, but a few groups genuinely do need to tread carefully.
A bowl of white rice carries around forty-five grams of net carbs, which is more than a whole day’s allowance on most keto plans. So rice, in its ordinary form, is out. What people miss is not really the rice itself but the job it does: a mild, fluffy base that soaks up sauce and bulks out a curry or a stir-fry. Several low-carb swaps do that job well, and a couple do it badly enough to put you off for life.
Ask a room of keto eaters what they had for breakfast and a good half will say eggs. There is a reason they turn up on nearly every low-carb plate: they are cheap, quick, filling and about as close to a purpose-built keto food as nature manages. The questions people actually worry about are narrower. How many is too many? What about the cholesterol? And is there a better way to cook them than the sad, rubbery scramble?
Most people need roughly 1.2 to 2.0 grams of protein per kilogram of body weight per day on keto, leaning towards the higher end if you train hard or are older and want to hold on to muscle. For a 70kg person that works out at about 85 to 140 grams a day. The mistake beginners make is setting protein too low, not too high, usually because they have read somewhere that protein is dangerous on keto.
The best oils for keto cooking are olive oil for most of your cooking, a cheap neutral oil such as refined rapeseed for high-heat frying, and a better extra virgin olive oil kept aside for finishing. None of them adds carbohydrate, so the choice is about heat, flavour and cost rather than staying in ketosis.

Somewhere in the first few weeks of keto, a lot of people notice they feel cold: chilly when everyone else is comfortable, cold hands and feet, reaching for a jumper or an extra blanket. It is a common complaint and it takes people by surprise, because nobody mentions it. The reassuring news is that it usually has ordinary causes, most of them fixable, and for many people it passes as they adapt.
