Ok Here’s the thing. Keto since Dec 2017… Had a longer than usual keto flu. Finally got enough salt. Fast forward to mid Feb. Have been IF for like the beginning and tried my first EF. Made it about 40 hours and my brain says eat. It felt funny but bonce I ate I felt better. Working on my IR I decided to try ADF this month. The first week I managed all three times. But hour 36 had the funny feeling in my head. I wish I could describe it better. Perhaps bonking? I have tried to work through it. Bone broth with salt keto aide. But it just got worse . I gave up and ate. Felt better after an hour. This morning the same thing. Had my coffee with cream butter and coconut oil. Still felt out of it. Tri ed Ketoaide again and started to feel better. By the way I did eat Friday evening. My salt intake has been a little low. Need to remedy that. But this odd feeling in my brain. Like something is swirling around up there. Maybe rearranging things. Any ideas?
Something happening in my brain
You just gotta listen to your body, I didn’t start with intermediate fasting till I was like 6 months in…
When I fast, I don’t have any funny feelings in my brain. I don’t get light headed, I just go through period of hunger and boredom (from not eating.)
Sounds like your electrolytes or something is off.
I take;
Multivitamin
B12
Probiotic
Fish Oil with D Vitamin and Omega 3
Calm Magnesium Citrate
MCT Oil
Morton Lite salt
Daily.
Right now I’m on an EF and skipping MCT but taking ketoaide twice a day.
I’d say listen to your body, do IF and visit your doctor for some lab checks. Maybe something has changed physiologically and you are missing something.
Good luck!

Just curious about this, can you describe the feeling in more detail because I think I might know this familiar feeling?
I’m agreeing with Bahrutile… On SAD diet we’ve learned not to trust our bodies… But in keto we have to relearn to trust our bodies. Fasting on keto comes from not needing to eat- our bodies are fat adapted and ready to harvest our body fat. It will tell you when it needs supplementation from eating. It sounds like you are mentally ready to lose weight fast and want to force fasting on yourself from a place of willpower. That’s great, but it sounds like when you “cave in” and eat after feeling lousy, you feel much better… I would wish you too not think about it like "caving in"and not add the unnecessary guilt and frustration and instead just keep calm and keto on… Trust your body. Sounds like you’re doing great! Good luck
Bunny,
It literally feels like my brain is rearranging itself. I’m not lightheadedness to the point of passing out. But sometimes it feels like something is going on up there. I do take one psych drug Seroquel xr 150mg. The feeling starts for a few minutes then stops. Then I may not have that feeling for another week or so. Or even a month. I have no clue what starts it or stops it. It just feel like my brain is doing something up there.
Are you consuming caffeine? I’d wager that is a factor if so. Try leaving it out and see what happens. Good luck.
Not the first time I’ve heard that. But maybe I need to seriously consider it.
I’ve become so sensitive to caffeine on keto that it makes me feel unsafe to drive for example. I don’t know why the sensitivity but when I learned caffeine was my problem my life got a lot better. I thought I had developed a serious anxiety disorder. Pretty crazy stuff.
Huh! Ok will try weaning off. I love coffee. Will have to try a breakfast tea with HWC.
Neural Oscillation & GABA
McGovern Institute for Brain Research at MIT It has been recognized for decades that the brain produces rhythmic patterns of electrical activity, colloquially known as ‘brain waves’. These rhythmic patterns reflect the activity of thousands or millions of neurons, each with its own intrinsic rhythmic tendencies. If each neuron is firing independently of its neighbors, the overall effect will appear as noise, but when they become synchronized, their combined effect can be detected as rhythmic oscillations, which in some cases are strong enough to penetrate the skull, allowing them to be recorded noninvasively with electrodes on the scalp.
In this video, McGovern Institute director Bob Desimone illustrates a mechanical analogy for how this synchronization occurs; the ticking metronomes influence each other through the side-to-side movements of the board on which they sit, and over time this causes them to lock into a synchronous pattern.
Neuromodulation (biology)
In addition to fast direct synaptic interactions between neurons forming a network, oscillatory activity is modulated by neurotransmitters on a much slower time scale. That is, the concentration levels of certain neurotransmitters are known to regulate the amount of oscillatory activity. For instance, GABA concentration has been shown to be positively correlated with frequency of oscillations in induced stimuli.[27] A number of nuclei in the brainstem have diffuse projections throughout the brain influencing concentration levels of neurotransmitters such as norepinephrine, acetylcholine and serotonin. These neurotransmitter systems affect the physiological state, e.g., wakefulness or arousal, and have a pronounced effect on amplitude of different brain waves, such as alpha activity.[28] …More
Glutamate and GABA are two very important neurotransmitters that are responsible for focus and relaxation, respectively. Proper neurological function requires a balanced interplay between these two.
An imbalance in these neurotransmitters, which often manifests as an excess of glutamate, has been associated with brain disorders such as autism, Lou Gehrig’s, Amyotrophic Lateral Sclerosis (ALS), epilepsy, and mood disorders. Additionally, those with excess glutamate and low GABA levels will tend to feel anxious, have trouble sleeping and experience brain fog.
Chronically elevated glutamate is highly inflammatory as it continuously overstimulates brain cells. In a healthy person, excess glutamate should be converted into GABA to help balance neural processes. Following a ketogenic diet has been shown to help facilitate this conversion (6). The immediate effects of this are improved focus and lower levels of stress and anxiety. …More
Keto Depression
The Ketogenic diet on Dateline 24 years ago (Charlie Foundation)
That something in your brain sounds like something I experienced in the first 4-6 months of keto on occasion - and I think many adjustments with brain nourishment and gut microbiome along with mineral balances definitely has something to do with it. It took me awhile before I didn’t have to take extra salt morning and night and for snacks just to maintain whatever processes were going on in my head. Lots of people by midlife in the S.A.D. have excess water/congestion in the head - and that will get adjusted via ketosis and proper electrolytes. I know mine did!
Regardless, sea salt (has trace minerals that sodium chloride/Morton’s does not) supplementation is very beneficial. Dr. Phinney recommends 2-3 grams of sodium per day for those following LCHF/keto (2.3grams of sodium being in one teaspoon of salt means about 1.5 teaspoons of salt per day - especially when still getting fat adapted, and also in times of extra stress or travel.
Most folks don’t reach 100% fat adaption for months - as explained by Dr. Phinney. I didn’t start any IF till about month 4. And you’re already aiming for EF? Unless you are 100% fat adapted and, considering the Seroquel, under a physician’s supervision, it’s really unadvisable! EF can be stressful and even risky in a couple of ways otherwise.
Typically folks who take medications to have to reduce dosages due to former dosages becoming too strong with ketogenically fed brainz - potentially causing side affects to arise due to excess medication. So you might want to check in with your healthcare provider about possible reduction protocol for the Seroquel. 
Thank you. Seroquel helps me sleep but I may need to taper down. Thank you Mary for taking the time to respond
OMG Bunny thanks for taking the time to find this research for me. I have sleep problems so this article was very helpful. Thank you again.
