MCT and the runs ?

by 2401 · August 10, 2013 at 01:21 AM

If im not used to it, a mere tablespoon makes painful cramps and water diarrhea within an hour.

I titrated slowly and now safely take 15g with my coffee and 15g with my lunch.

Safely....or so I thought.

While I am not getting any pain, nor immediate bowel reactions, I am shitting water or soup on every movement, for the past month or two.

I didnt associate it with the MCT because of the lack of any pain, gas, cramps, nausea, or immediate movements.

So I've been eliminating things methodically to no avail. I'm gonna try to eliminate MCT next, but I'm loathe to do so bc it's great energy and a great keto-switcher.

Anyone else fail to get accustomed to MCT over time?

Yep. Of course, I have to enter fifteen characters just to say yep.

I really wanted to eat a lot of fat because I wanted to stay pretty much ketogenic most of the time. I can eat fatty foods, add a chunk of butter to something, but MCT oil at levels people usually use to generate ketones can easily cause distress. I seem to be allergic to coconut oil, or perhaps to coconut in general, since it is usually proteins that cause problems- though coconut also has FODMAPS. If it is any consolation, you can tell yourself it isn't really paleo, because it is processed and all.

Ever try juice of potato ala Ray Peat for ketoacids? I did. It was interesting, but there is starch too. Now, since Nikoley did the resistant starch thing, and the main thing they are using to dose with resistant starch is potato starch, maybe I should pull out the juicer again and just try to drink the raw juice. Peat says to cook the hell out of it because he doesn't like starch for some reason, but he also doesn't want to believe in any new research either. I don't know if the ketoacids need cooking or not, and the resistant starch doesn't seem to cause blood sugar or insulin spikes like regular starch would. Now, if only it didn't turn brown so quickly.

Yes, when I first started experimenting with MCT and coconut oil I found that there was definitively an upper limit to how much I could tolerate without some kind of GI distress. For me, it seems like the max MCT I can handle is about a tablespoon, and coconut oil a little more than that.

As I understand it, your gall bladder only produces so much bile salts on a daily basis to break down fat, and when you hit it with a load of fat all at once, it's going to empty out in response (depending on how much you have). If it is depleted and you hit it again with fat later, the body is going to have a tough time processing that fat and may just push it through.

It then takes another day to build up the bile salts stores, and if your fat intake stays relatively consistent your body will adjust over time and produce more to compensate for the higher fat intake. However, I've also heard caution that if you decrease your fat intake, you should do also it slowly to give your body time to adjust so that you end up with an excess of bile salts and possible gall stones down the line.

Maybe an over-simplification of how it works, but that's my layman's take on it.

Never tried straight MCT, but from what I understand, since it's so easily digested, if you take it straight, it'll run right through you. Can you try combining it with meals in both cases (not just lunch) and see if things clear up?
