Laura, I am am suffering the same issue as you!
I started the ketogenic way of eating Feb 2018 and had great results. I was fat adapted and was full of energy, required less sleep and could fast.
Just like you life happened. I cheated a little here and there, by the time the holidays hit, I cheated more and cheated my way out of fat adaption. Coupled with that, I injured myself back in November and had to give up my favorite form of exercise and I did not replace it with anything else.
After gaining back 13 pounds of the 17 I lost, I finally decided that I need to take control of my eating. For the past month I have been very careful with what I eat, I track with Carb Manager and I use a blood monitor.
My ketones typically register between 0.8 and 2.2 and my glucose is consistently under 100 - 2 hours after eating.
However, my weight is not budging! It is so frustrating!
I decided to do a 5 day egg fast last week and I lost 1 pound. My body simply refuses to give up the weight. I am not very overweight, would like to lose 20 pounds in total and have my clothes fit better.
Like you, I consume dairy, occasionally eat nuts, rarely consume artificial sweeteners. I do drink alcohol (whisky on the rocks or red wine) and gave it up during my egg fast and have now decided to consume alcohol on weekends only.
I am beyond baffled! It feels like my body is fighting me and wont give up the weight. It is frustrating and and discouraging.
I did notice a link CarlKeller posted which is very informative. Maybe we just need to be more patient - but it is hard when I am not seeing results. You are not alone
