GERD better?

I'm about 1 year in to keto. with that said, I had three months or so where I completely reverted - but I'm back now. I have made an observation and wonder if anybody else experienced this. Prior to keto I was starting to get a lot of reflux, not enough for me to want meds, but certainly it might occur a few times per week. I didn't really notice that it had completely gone away when I started keto, but when I reverted, it came back hard after every carby meal. I, being not the brightest bulb, still didn't put it together. Now that I have been back fully keto again, I just don't get reflux anymore, like ever. I don't think it's weight related, because the effect was too immediate.

Has anyone else noticed this? Any theories as to why GERD is better on keto?
