Can we start a club?? I gained 3 pounds in one day, since yesterday.

Our bodies are complex, it bounces and reacts.

Eating sauerkraut , the real versions, have great health benefits. Microbiome needs 2-3 weeks to adjust. Than is the time line for changing feeds for my horses and 🐑 sheep. So one day of a big change could be off putting.

Perhaps it means your gi needs help and support to be it's best. Like how to provide BOTH the probiotics AND prebiotics. After years of fortifying, my GI can tolerate WELL any quick changes. Took years of thoughtful intentional work to buy it make, then eat the right foods.
Very small amounts every other day to start is what worked for me.
