I have been full Paleo for about 9 months and recently diagnosed with Hashimoto's. So, in response to that diagnosis, I took out all nightshades, eggs, nuts,..etc. I decided to eat only meat products and one (or two) cooked squashes each day. But, after a couple weeks on that diet, I learned I would be best off to eliminate everything except meat/fat products for a few weeks. Low in behold, I came down with a headache after two days with practically zero carbs. Today, I ate my regular breakfast of meat, still sporting a headache and decided to eat 3.25 oz. beef jerky at (11 am) that contained about 18 grams of sugar and it cut the headache immediately. Unfortunately, around 2 pm I had terrible diarrhea likely from the jerky - so I won't eat that again. Aside from the jerky diarrhea, do you think I messed up ketosis by eating that amount of sugar? And, will eating 20 grams carbohydrate from cooked squash hinder healing of my gut/Hashimotos? Do you think it is worth while to go about healing with this meat diet/ketosis for a few weeks in a fashion of a couple days all meat and one day with a bit of carbs from one cooked squash? Or, should I deal with the headaches in hopes my body will adjust to ketosis and they will go away?
Sheri - I am on a group on facebook. It is called Stellar Health Through Ketosis. It is being run by Dr. Bruce Fife's wife, Leslie. He is an expert on ketosis. She is strict on the group wanting us to really be in ketosis. If you are interested, you may want to join and learn with the rest of us. I am sure that the headaches will go away soon. Stay hydrated, up the fat in the form of coconut oil!
I'm certainly not a doc or expert but will share my experience. I read a few studies that suggested I go VLC (aiming for Keto) for bipolar. I gave it a try last week and immediately got headaches. I went on with this for a few days and it sucked - the headaches were consuming me. So I decided to go back up to my original carb intake then gradually go down. I was at about 125 carbs/day last Friday and I'm taking out about 5+/- per day. I'm noticing a positive difference in my mental state without the headaches.
It sounds like you're shocking your body. A gradual elimination may be better and it is working for me. I figure, hey - I've had this mental issue for some time now and I'd rather treat it properly than cause an onslaught of other issues with body-shock. Hope it helps!
You might want to look at this posting regarding body adaption to a low carb regime.
Lots of folks report headaches in the comment section. I personally never experienced any problems converting to low carb/ketosis with my 75-80% fat, 10-15% protein, 5% or less carbs.
Dr Mike Eades also addresses the conversion problem:
Eight weeks. That's how long it took me to adapt to ketosis, during which time I had brutal headaches. During the first four of those weeks, I had 15 days of headaches, 9 of them migraines. During the second four, I still had them badly enough to be a miserable wretch of a human.
It passed. I adapted. Now I can eat more carbs or fewer carbs and not suffer headaches. My body is much more adept at fluidly moving between ketones and glucose as needed.
