Reintroducing starch after LC

Answered on August 19, 2014
Created August 18, 2012 at 8:18 AM

Hi hackers,

I've been LC for about a year but already added fruit back into my diet without any issues. Now I intended to do the same thing with starch (white potatoes, sweet potatoes don't agree with my stomach).

Problem is, whenever I eat lots of starch, I notice dizziness and fatigue a few minutes later. Pure glucose (as in starch) is supposed to elevate blood sugar higher than the glucode/fructose combination in fruit. Additionally LC might lead to insulin resistance (simply because the cells prefer free fatty acids). Could those 2 factors be causing this reaction? Has anyone experienced anything similar?

Cheers!

@Lady_Arwen: I ate under 50g of carbs per day and felt actually too weak to do any workout at this time. Also sleep was really bad, I woke several times per night - often to use the bathroom (water retention?). @Jamie: That's really weird. What kinds of fat do you eat? Ray Peat says PUFA do block the thyroid and MCTs support it. And what effect does copper have on thyroid function? Maybe I should eat more liver.

(By balance copper, I mean, take a copper supplement once a week, and eat more copper foods)

Thats interesting. I personally became hyPERthyroid after going low carb, and ive had to restrict iodine and balance copper to remove the symptoms. Sat fat in itself seems to be thyroid stimulating. My last tsh was 0.06 and free t4 18.0. That said, I still eat fruit regularly (I am not very low carb). It does seem weird how the thyroid is so fickle.

What is your activity level Thorny and define LC? Some people define LC as below 150 grams, 100 grams, 50 grams, etc. per day. How is your sleep?

Great article, especially the part about thyronamines!

Don't have the blood test at hand, but if I remember correctly TSH was at 2.5mU/l. Also I had frequently cold hands, fatigue, dizziness, orthostatic hypotension, a general feeling of weakness and a heart rate of approx. 50-60bpm. Calorie intake on the other hand was around 2200kcal. All those symptoms went away after reintroducing lots of fruit. But pure starch=glucose seems to cause issues somehow.

What are the symptoms of your thyroid going into hibernation? No, I am totally agree that our bodies need starches, I don't think that Paleo should be LC for healthy people. I really would like to know what you are feeling on LC.

^ why does your thyroid go into hibernation? (or perhaps if your not getting blood tests on your t3, t4 etc, what symptoms do you experience?)

Yes! Blood sugar spikes cause crazy dizziness in me. It just dawned on me this week as a matter of fact that it was the reintroduction of carbs that was giving me similar symptoms to what I experienced when I was a pasta-loving Weight Watcher. Always dizzy after lunch...

Hi, it's just that my thyroid goes into hibernation when I'm LC for a longer time. Aside from that, I don't think the human body would have developed the ability to digest starch, if it was that harmful. (I mean tubers, not grains of course :) )

^ Thats a pretty good article. Especially about longevity actually. Its made me consider moderate protein, along with my existing lower carb. Not that I go over his 1 gram/kg of lean mass/day all that often, but its a really interesting thought, the whole "starvation mode" preservation idea regarding genetics etc.

I really want to know - why do you want to go back to starches? I recently went LC and I am feeling SO MUCH better! If you are trying to go back to carbs - is there a reason why? Is there something wrong with LC? Please answer!!!

I've always added some fat to the potatoes. Do blood sugar spikes also cause dizziness for you?

Do you eat your carbs with protein and fat in a mixed meal or by themselves?

I suggest you add carbs in small amounts and always in a meal with protein and fat to slow down the digestion and absorption of the starches. I have to do this as I am sensitive to carbs and blood sugar elevations

Perhaps start with small amounts of lotus root, or parnsip (which are lower in starch than potatoes etc), and work your way up very slowly.

I have not experienced this myself, because while I am low carb, I am not VLC, and I eat fruit etc (simple carbs) pretty regularly. Then again I am not eating starch, and high enough a glycemic load might still give me some kinda issues.

Id guess this is most probably a blood sugar thing.

Its fairly common after a period of low carb (especially VLC), around PH, once re-introducing carbs and getting all sorts of weird symptoms ranging from high BS (sleepy) to low (dizzy, heart palpitations, anxiety, irritation). I am not really familiar though with low or high blood sugar symptoms tho, on a personal level.
