How can I tell if I'm in ketosis?

Hello, Keto veterans out there! How do I know if I'm in ketosis? I know it's not overly necessary to know, but I'm curious.

I've been sticking to Keto faithfully for 5 days now, keeping my macros at 5%C-25%P-70%F. I've never been over 20g of net carbs since I started, and I have been hitting my 70-75% fat macro almost perfectly.

I have read about the "ketosis" signs to look for ('fruity' breath, different smell to urine, metalic taste in the mouth, more energy), but I haven't noticed any of these. The only thing is that I lost 2 lbs. overnight. I also haven't been experiencing the dreaded "carb flu" that everyone talks about, but that may be because I've been keeping my fat intake quite high (70-75%) and drinking plenty of water (10-12 glasses at least). Also in the past month I have been reducing my carbs gradually down to about 100-125g/day, until I started keto five days ago.

Is there anyway to know for sure?
(Unfortunately, I don't have any Keto strips, at the moment - they don't sell them near here, so I had to order them online. They're in the mail.)

    My personal glucose-to-ketones transition may be unique, but I remember sitting at the dining room table, doing homework on my laptop, when I got the sudden urge to go for a run or exercise or something.

    I ended up cleaning up the whole apartment (at the time I was attending college and had 4 housemates - I'm sure you can imagine how messy it was). I literally could not continue sitting and clacking away at the keyboard. I had to move.

    That was my transition and I knew, without a doubt, I had entered ketosis. Perhaps your experience will be similar.

    It would be virtually impossible to NOT be in ketosis at this point. You're well on your way to being fully keto-adapted.

    Many people do NOT experience those. Those are signs during the initial entry into ketosis usually experienced by someone who's done a much-more drastic dietary change than you've done.

    If you're used to eating 50-60% carbs, then go into ketosis, you'll likely experience some or all of those symptoms for a day or two, sometimes more. For someone that's reduced carbohydrate more gradually, and is already relatively low-carb, the shift is often asymptomatic.

    The weight-loss is likely a result of lost water/glycogen as you push further into keto-adaptation. Because you were already quite low-carb, you'll likely not experience the 'keto-flu' or other symptoms.

    Ketostix sometimes don't even register, especially for those of us that stay well-hydrated. If you test on a day when your water intake is lower, you'll most definitely get a pink result. Purple would mean you're very dehydrated ...

    If you've already been under 100g and at a reasonable caloric intake, it's also quite possible you already WERE in ketosis and didn't know it. Many people mistakenly think you need to eat 20-30g to be in ketosis, and that's not necessarily the case.

    It's easier to GET ketogenic starting at 20-30g a day, and some find best glycemic control, etc., at very low levels, but most people eating 2000+ calories a day can easily maintain ketosis/keto-adaptation at 100g a day of carbohydrate if they're not sedentary.

    As an anecdotal example, for me to get OUT of ketosis takes 2-3 full SEDENTARY days of 150g + carbohydrate intake. There are some people that think I'm not ketogenic at 50 or 70g of carbohydrate a day . . . they're simply misinformed.

    Lyle McDonald - a leading expert on ketogenic diets - states:
    "Since many books give the 30 g/day value for a ketogenic diet, folks get a little anxious about carb intakes that are higher than that.

    However, strictly speaking, any diet with less than 100 g/day of carbohydrate will cause ketosis to develop to some degree (more ketones will be generated as carbs are lowered)."
    Those who engage in exercise, especially strength-training, can often eat a little more than others without issue. Lyle did some calculations (rough, by his own admission) and states:
    "The carbohydrate requirements for weight training actually aren’t that great. I did some rough calculations in The Ketogenic Diet and concluded that, for every 2 work sets (assuming a set length of 30-45 seconds) or so, you’ll need 5 grams of carbohydrates to replenish the glycogen used.

    So if you did a workout containing 24 work sets, you’d only need about 60 extra grams (24 sets * 5 grams/2 sets = 60 grams) of carbohydrate to replace the glycogen used."
    24 sets is 4 sets of six exercises ... which is a fairly heavy day for many of us. I typically do 5 sets of 4 exercises every-other-day. This would be 20*5/2 = 50g ... however I'm a little larger than most so I'll typically have 50, 70 even 90g of carbohydrate on my strength-training days, depending on the effort.

    So, what I'm saying is if you were exercising, especially doing strength-training or any anaerobic interval training, etc., while eating 100-125g of carbohydrate a day, you were quite-possibly already IN ketosis . . .

    What a wealth of great info! Thank you so much for sharing, both of you!

    I'm excited to think that I may in fact be in ketosis! :-) I guess I just supposed that it would be a lot more difficult than this. I'm really glad I decided to reduce my carbs gradually... over a month's time. It wasn't easy, as I love my whole grains, but as I slowly cut them out I started to feel better. The gradual carb reduction may have saved me a lot of headaches (quite literally). I did feel a bit more "up" today than I normally am (I struggle with severe fatigue most days). I also woke up earlier than I regularly do, feeling a bit more 'awake'. That's quite unlike me in the morning. hehe!

    I know that this initial weight loss is pretty much water - I'm not a huge proponent of frequent weigh-ins, but will be doing so more often during my first month doing Keto just to get an idea of water loss vs. fat loss (I'm monitoring my BF% as well). My sodium is consistently high as well, so perhaps that helps.

    I haven't ventured into strength training yet -- just mostly cardio and regular interval training (speed walking, dancing, Zumba). Hoping to start soon... just waiting on a kettlebell DVD. :)
