After Christmas and the COVID shutdown, I had drifted way out of keto.  I’ve done water fasting before max 7 days and thought I would try 10.
The idea sat there a few weeks until I saw an appropriate time to start.  I had dinner Tuesday, thence only water (and some salt).  I did a ‘Vitamin C flush’ on day 3 and over the fast had a cup of tea and a cappuccino for social reasons.
On day 10 I started to get some shoulder and upper arm weakness and a little bit of blurry vision.  The body must know what the plan is because up to then I was feeling 100% and full of energy.  I do need early nights when fasting or I feel tired.  But I didn’t feel cold like I did last time.
Over the fast mainly toward the end, I did a lot of recipe surfing.  I found about fermenting and pickling.  I had seen someone saying that after fasting it’s good to take some kimchee for the microbiome.  I didn’t know what kimchee was, and thought kombucha was for nutters.  So on day4 I set up some cucumbers and also cabbage to ferment.  So pickles and sauerkraut.   It came out great on day 11.
As it turned out, I didn’t feel much like eating Friday night so left it to Saturday making it really about 10.3/4 days.
I tried making some mayo which turned out fine.
I broke the fast with ~50g nuts, and some pickles.  Soon after, some celery, capsicum and cucumber with liverwurst and mayo dip.  A 0-carb beer and a black coffee.
So the outcomes were;
- lost maybe 8kg
- learned lots of new food tips
- got myself into pickling
- clothes fitting much better   
- overall feeling much better
- prefer black coffee to cappuccino
- feel energised to do keto OMAD
