How do you know when you are in ketosis

Options
Hi all,

I just started eating low carb, keeping my net carbs around 40 (total carbs up to 59-15% from total calories intake), to begin with and not suffer too much.
My questions are,
1) how long does it take to be in ketosis
2) how do you know when you are in ketosis.

Thanks in advance for your help :smile:

    When you're in Ketosis, your body is converting fat into ketones that it uses for energy. So ketones will be present in your urine. All you need to do is pee on a strip and watch it change color.

    Ketone Strips @ Amazon

    As far as being able to tell by just how you feel, you should have more energy, mental clarity and you'll just feel better. Personally I also have moments of hot flashes when my metabolism kicks into high gear, however thats just me, this may not be the case for you. The only REAL way to tell is by doing a lab test such as the dip mentioned above.

    That's not always the case. It really is person to person. I didn't have that at all.

    definitely true - when I'm switching into ketosis (like when I have overloaded on carbs for a re-feed), my urine smells like cat piss (really strong nasty smell) :o

    Best way to tell is ketone blood tests, but that is too expensive to be worthwhile in your case.
    Next best method is urine strips (mentioned above), which can be bought OTC at Walgreens, CVS, local pharmacy. Look in the diabetes section or ask the pharmacist. Or just buy online as suggested above.

    I experience this too...somedays it just feels like I am running a fever...all day...it's weird to feel that warm all day and still feel really good, not like having an illness related fever at all.

    I wish... sweaty bits are fine. Breath that can knock over a tree and wee smelling like catpiss. I "know" when I am in ketosis.

    @KetoLady86 ; @idocdlw:

    Glad I'm not the only one. People at work think I'm nuts when it happens because its quick. I start fanning myself and then I get this sudden burst of energy and want to get up and do stuff. It happens more often after I've eaten something, but not always.

    As a matter of fact last night at work when I got there, I was freezing. Kept my hoodie on and shut the windows. And then all of a sudden, I couldn't get my hoodie off fast enough and the last thing I wanted to do was sit down. LOL

    Wow, so many answers, thanks everyone.
    I still can't tell about me when I'm in ketosis, about energy, now and them I'm full of energy (I'm hyper) so it is hard to tell.
    I'm going to buy those sticks, and take note of the changes in my body, so next time I'll know when I'm in ketosis whitout using the sticks.
