Warning against Ketogenic diets during pregnancy page

[activia]

There are studies done that found that if women are on a ketogenic diet during pregnancy the gene expression on the baby is changed as the baby thinks it is going into a starvation environment and changes their metabolism permanently to store fat. Ketogenic diets over long periods of time can also cause your t3/t4 ratio out of whack which screws up your thyroid.

Final Note: Primal/Paleo does not have to be ketogenic

I suppose if Grok's mate was PG and only ate meat, it would account for the *thrifty gene* we keep hearing about?

Seems very plausible. I'm glad I found that out before hand because I'll certainly make a point to eat a lot more carbs then I do now when I'm pregnant (since now I only eat >100g a couple days a week, with some days <50)

Hi, do you have any links for the studies? When I googled I didn't have much luck. I do keep my carbs above100 anyway (due to an already-screwed-up thyroid) and have increased it to be over 150 now. So it's not a concern for me, but I'm pregnant and am curious about it. Thanks!

Sorry Chris said it during a podcast. I'd have to listen to it again to catch the exact details enabling me to find the study. It's possible it wasnt done on humans? He's just starting to get transcripts and links to the studies in his podcasts.. and this is an older one that hasnt yet been transcribed, hopefully soon. After I'm done listening to this one I'll get back to that one and see if I can find out more details for ya. Or you can listen yourself and add to this thread

Yeah, where are you getting that info from?

maybe this is it?

I'm still working on it.. I am running it now, its about mid way so it will probably be about 20 min

Hi,
I just googled, and found this page Ketogenic Diet For Pregnancy | LIVESTRONG.COM
It only mentions diabetic ketoacidosis, and says "No studies have specifically tested the effects of ketosis during pregnancy" This article was dated July 14, 2011

It's specifically to do with blood sugar levels during pregnancy...
Ideal: 63-79

So its good to test your blood sugar during pregnancy..a lot even.

I think this is what he is talking about: Diabetes Update: Normal Blood Sugars in Pregnancy which was published in October 2011..here they found that too high blood sugar can cause high birth weight and that their genes were different, so he is saying that the inverse is true as well.

So very low carb diets will cause you to have very low blood sugar, which is what is causing what I said before. So he is saying that its key to keep your blood sugar at a "middle" ground. So you want at least 50-100g during pregnancy. To keep you out of ketosis.

Chris Kresser talks about this a little in his personal paleo code. Probably good to have more carbs for pregnant women.
