100g of carbs is way to high to maintain ketosis for a normal person even powerlifters only carb up those amounts preworkouts I cannot imagine you are in a state of ketosis eating 100 carbs a day. I do not know what diet or lifestyle you are following or getting your diet and macros from, but it is definitely not a Ketogenic diet. You might want to read more of the forums for beginners threads or ask others there are a ton of informative materials to learn from and find a Keto macro calculator and create your first macro it will guide you then you can adjust it as your diet and body progress. The Keto diet is high fat, moderate protein and low carb (I say very low carb). Keto diets range from 50g of carbs to as close to 0 as you can get. The high end of 50 carbs should only be used by those who are either carb uppers for limited time like lifters, people needing a slower entrance into Keto adaptation generally due to health concerns, or actual Keto adapted persons who's system can now regulate the infuse of carbs properly and maintain Keto adaptation. Ketosis is not and should not be the deciding factor to look at as the overall goal should be to become Keto adapted and things such as weight loss will happen naturally during and after this transition. I and many others in the forums would be happy to help you anyway we can. Keto on!!!

Ketosis is normal overnight. Your body will have broken down all of the carbs you consumed and will be sustaining your body on fat stores. That happens to almost everyone.

I low carb for health/medical reasons. I have type 1 diabetes. I keep my carbs at or below 100 grams a day and about 1600 calories a day. I do not strictly follow net carbs, except when giving insulin for my carbs.

I disagree that 100g of carbs will not result in ketosis. I think it probably will, mild ketosis, especially early on in the diet.

Most people who are not low carb high fat need a minimum of about 130g of glucose per day. If you are eating 100g of glucose, you are making ketones and extra glucose to make up the difference. If you are exercising, you'll be using even more glucose because your body has not made the switch to preferring ketones as a fuel. You wouldn't be fat adapted yet.

Fat adapted takes days to weeks or even a few months. It refers to the state where the body stops using glucose as its primary fuel, and glucose needs drop. The brain will start using less glucose and so will muscle, and other parts of the body. There are a few things that must use glucose (like red blood cells) but the daily amount of glucose used by the body falls. I think I've seen it can go as low as 40g (can't remember where I read that now... or when I made that up in my head LOL).

Anyways, at 100g of carbs per day, you will be in mild ketosis. Most people who low carb (under 100-150g of carbs) will move in and out of mild ketosis once in a while, especially if there is fasting (like overnight). People who eat fewer than 50g of carbs will be in a state of ketosis most of the time.

Withe the ketostix/pee sticks, if they are changing colour you are in ketosis. If they don't change colour, you may still be in ketosis. As the diet progresses, some people stop spilling ketones into their urine. My ketostix are rarely positive anymore unless I severely restrict calories or fast.

BTW, you don't need carbs for exercise. The less reliant your body is on glucose, the less likely you are to hit the wall. Endurance may even increase.

While it might put you in a state of burning ketones off and on throughout the day, that does not make it a ketogenic diet. A ketogenic diet is very specific. It's not simply a diet that produces some ketones on a regular basis.
It does make it low carb and if that's giving you the results you're looking for there's no reason to aim for full time ketosis.

I agree totally with the above. And keep in mind that the ketostix are only an indicator of ketones, and can't tell you if you're truly keto-adapted.

Regarding the amount of carbohydrate you're eating ... I can easily eat 100-150g of carbohydrate on the very occasional day, and maintain ketosis - but only when I'm doing something like a 4-5hr bike ride...

I typically keep mine around 60g to maintain strict ketosis (some days more, some days less, depending on exercise) - but I'm also a big guy with a high metabolism.

But as Sunny_Bunny_ said, if you're getting the results you want, you may not need a true keto-adapted state.
