How to stay in ketosis
« on: November 18, 2010, 04:42:55 PM »
What's the maximum amount of carbs that can be consumed without getting out of ketosis?

Following a few particularly low carb days earlier in the week, I had killer headaches, but felt great today.  The ketostix are saying that I'm in ketosis, and I'd like to stay in for a little bit to let my body adjust and hopefully prevent the headaches in the future.

To stay solidly in ketosis, I stay below about 15g carbohydrate. A lot of sources say 50g, but that is iffy for me.

Probably the best thing to do is to skip all fruit for a few days.

When I was younger I  was in ketosis on 85 to 90 grams of carbs a day. But I was running 5 to 7 miles a day.

Sounds good.  Thanks.  I'm not exercising very much these days, so I doubt I could eat many carbs before coming out of it.

I am not eating any fruit at all. The ketostix are staying normal. I am training heavy 4 days per week. how do I know if I am in ketosis? Some people say that the ketones in my body might be getting used up by the exercise. I still have a bit of a headache a couple of days now. I never get headaches

I read somewhere, very recently in fact, that some people lose more ketones through their breath and not through their pee, so they don't pee them out and, therefore, for them the stix won't show much - ergo they are not very reliable.

I'll see if I can find the article.

I know when I'm in ketosis because I do get a strange pressure feeling in my head that feels as if I'm gonna get a bad headache - I normally don't get one, but I also feel similar in my body to when I've got low blood sugar as well. It's a weird feeling.  Oh and I pee a lot too.

All the symptoms are usually eradicated as soon as I eat adequate protein/fat (usually at dinner), and then they flare up again the next day.  I've never managed to stay in ketosis for long though because somedays I eat too much fruit.

I wish all I had was strange pressure.  For me, it was more like a vice being tightened around my skull, and I was really thirsty.  I feel great now, though.  No weird breath, as far as I can tell.

Yes, running like a crazy person is not the best way to achieve ketosis.

Don't get me wrong.....it may not be a headache in the sense of 'head ache' but it's not a pleasant feeling at all, it's horrible, and dominates my entire cognisant ability i.e. I can't think straight, and I crave carbs too when I'm in it.  Obviously, this is because I've never stayed in it long enough to get used to it.

That's my next goal.

You eventually get accustomed to ketosis and don't get headaches. Then friends invite you for dinner to thank you for a favor you did and you are back to the starting point again.

(by the way if you cheat and have popcorn just have it the old fashioned way by cooking it in hot oil, salting it and drizzling it with melted butter.  If you are going to fall off the paleo wagon don't do it with that tasteless air popped crap.)

How long does it take (approximately, cos I'm guessing it will be slightly different for individuals) to 'get accustomed' ??

Yeah, I agree with Paleo Dude on avoiding packaged microwave popcorn. I ate that in college once (pre paleo) - don't know what's in that stuff but it can't be good - it was not pretty - think symptoms of the stomach flu. I never had popcorn again even the homemade stuff that I had eaten before without this reaction - yes - it was that bad. Glad I had never tried popcorn at the movies - would have made for a terrible date. It was probably so noticeable because I've pretty much always eaten what people now refer to as "clean" thanks to the way my mom and dad feed us.

On the headache topic - I find that I get them when I eat too much fruit - so it looks like it works in reverse too. I ate meat only for about 8 months so I was definitely in ketosis then but a few months ago started eating fruits and veggies again. I don't get severe headaches from it but it is noticeable when I eat too many carbs at once.

Oh that does sound miserable.  I had the brain fuzziness too - at first I thought I had the mother of all migraines starting, until caffeine didn't touch it (plus, I haven't had any bad migraines since switching to this WOE).   It took me about 48 hours to go from "OMG, just shoot me now" to, "Hey, this isn't half bad!"

Yeah me neither....I started to get really bad migraines about 2 years ago and was taking all sorts of harsh pain killer meds to combat them.  Since Paleo? Gone :D

When I get into ketosis, it feels to me like I'm going to get a migraine, it kind of never really gets there but threatens for hours. I feel weak, sleepy and fuzzy and there's this 'pressure' in my head that I can't shake.  It happened at work on Wednesday. I came home and pigged out on chicken and chilli beef and it went away, but I would have murdered for a chocolate bar.  I even got the money out to go and buy one but, fortunately, I managed to resist.  I decided that if I am going to get and stay in ketosis, I need to have adequate good food with me to keep me going. 

During my holidays coming up, when I won't need the extra energy for work, I'll experiment, and 48 hours is not long to wait.

It takes about 3 days.
