how do I know when my body is in ketosis without using test strips?

    Personally, the only way I can tell is ketostix.
    The reddit keto FAQ at http://www.reddit.com/r/keto/wiki/faq says this:
    Ketosticks/Ketostix is the name for test strips that measure the level of ketones in the urine. Whether correct or not, many ketogenic dieters tend to live or die by the presence of ketones in their urine. The presence of ketosis, which is indicative of lipolysis can be psychologically reassuring, however it should be noted that one can be in ketosis, defined as ketones in the bloodstream, without showing urinary ketones.

    Although up to 100 grams of carbohydrate will allow ketosis to develop, it would be rare to see ketones excreted in the urine at this level of intake. Since the only measure of ketosis available to ketogenic diets are Ketostix (tm) carbohydrates must be restricted below this level of ketosis is to be measured. As a general rule of thumb, dietary carbohydrates should be below 30 grams per day for ketosis to be rapidly established and for ketones to be lost in the urine. However, this value varies from person to person and depends on other factors such as protein intake and activity, which allows individuals to consume relatively more carbohydrate without disrupting ketosis.

    After adaptation to the diet, it appears that individuals can tolerate relatively greater carbohydrate intakes without disrupting ketosis. Although not completely accurate, Ketostix (tm) can provide a rough measure of how many carbohydrates can be consumed while still maintaining ketosis. As long as trace ketosis is maintained, carbohydrates can be gradually added to the diet.

    Since Ketostix (tm) only register relative concentrations, rather than absolute amounts, changes in hydration state can affect the concentration of ketones which appear. A high water intake tends to dilute urinary ketone concentrations giving lighter readings. Ketones in the urine simply indicate an overproduction of ketones such that excess spill into the urine. So it is conceivable for someone to be in ketosis without showing urinary ketones.

    Some individuals can never get past trace ketosis, while others always seem to show darker readings. There seems to be little rhyme or reason as to why some individuals will always show deep concentrations of urinary ketones while others will not. Some will show higher urinary ketones after a high fat meal, suggesting that dietary fat is being converted to ketones which are then excreted. Consuming medium chain triglycerides (MCT’s) has the same effect. Other individuals seem to only register ketones on the stick after extensive aerobic exercise. Finally, there appear to be daily changes in ketone concentrations, caused by fluctuations in hormone levels. Generally ketone concentrations are smaller in the morning and larger in the evening, reaching a peak at midnight. Many individuals report high ketones at night but show no urinary ketones the next morning while others report the opposite.

    A popular idea is that the deeper the level of ketosis as measured by Ketostix (tm), the greater the weight/fat loss. However there is no data to support or refute this claim. While some popular diet authors have commented that urinary ketone excretion means that bodyfat is being excreted causing fat loss, this is only loosely true in that ketones are made from the breakdown of fat in the liver. The number of calories lost in the urine as ketones amounts to 100 calories per day at most.

    Anecdotally, higher levels of urinary ketones seem to be indicative of slower fat loss. Individuals who maintain trace ketosis seem to lose fat more efficiently although there is no research examining this phenomenon. A possible reason is this: high levels of ketones in the bloodstream raise insulin slightly and block the release of free fatty acids from fat cells. This seems to imply that higher levels of ketones will slow fat mobilization.

    The ideal situation would seem to be one where trace ketosis (as measured by Ketostix(tm)) is maintained, since this is the lowest level of ketosis which can be measured while still ensuring that one is truly in ketosis. This should be indicative of relatively lower blood ketone concentrations, meaning that bodyfat can be mobilized more efficiently.

    No hard and fast rules can be given for the use of Ketostix (tm) except not to be obsessive about them. In the same way that the presence of ketones can be psychologically reassuring, the absence of ketones can be just as psychologically harmful. It is easy to mentally shortcircuit by checking the Ketostix (tm) all the time.



    Acetone Breath

    Acetone Breath, otherwise affectionately known as “metal breath” or “keto breath”, is the presence of ketones in your body being produced and turned into acetone. It will taste metallic and have faint wafting essence of ammonia.



    Changes in urine

    Ketosis not only changes your breath but your urine, too; it will start developing a filmy consistency and smell like its been distilled from dinosaur sweat. The potent smell change will be the most obvious.

    I definitely notice "keto breath" and that sweetish-metallic taste in my mouth.

    I also noticed a stronger smell in my urine at first, but either it's gone away or I've gotten used to it (or I'm drinking so much it's too watered down to smell).
  • HMMMMMM,

    The Keto Strips are definitely darker, but I've never noticed the Keto Breathe. Nor has my wife, fortunately!!! :wink: From what I've heard, that may be a good thing.

    I think the biggest sign for me was that headacheyness when I entered it, and I did notice the "filminess" to my urine.

    I am curious, though, what does "distilled dinosaur sweat" smell like? :laugh:

    Have an awesome day!

    Peace,
    Tom

    I never seem to experience the symptoms neither last year nor this year. If I didn't use ketostix, I probably would have never known. Might be because my carbs are much higher than Atkins induction level (around 60 g total). But, I remember many years ago I tried Atkins for about a week and I did notice the metallic taste in mouth.

    I wouldn't worry about any sort of definitive proof that you are in ketosis, just eat low carb and keep your net carbs low (I aim for 30 or less) and you'll get there. When you get into it, you'll know it, the increased energy etc will tell you. For me, I look at ketosis not as a goal of my diet but rather a result of my lifestyle. Live my life, enjoy eating the right way and ketosis is just the benefit not the goal.

    I never got "keto/low carb flu" or "keto/ low carb breath" like others have. I also find Ketostix to give too many false positives and inaccuracies.
    You can read one study here: http://www.dietdoctor.com/final-report-two-months-of-strict-lchf-and-ketone-monitoring and note the difference in studies. I find the only thing working for me that is accurate is a blood ketone meter.
  • When I started before I could switch in and out pretty painlessly I used to have a few days of just feeling rubbish before all of a sudden feeling on top of the world (on the good day - its started)

    As others have said the metallic taste and a new found need to drink water.

    The sticks only picked anything up for me right at the beginning, after a while you get so good at using ketones they hardly register on the sticks as they are not wasted through breath /urine so much any more.

    To be honest advice I have seen before and which ill repeat is just to relax, if you know with confidence you are sub 50g (better still 30g) and the weight is dropping dont worry about ketosis it will be happening. If you have not had a good drop after the first 7-10 days have another look over what you are eating and make sure there are no carbs sneaking in (common pitfalls are coffee i.e. count 1g per cup and milk)

    Good luck!
