I am still on keto, and it's continuing to come off. I'm not insanely strict with myself, so I'm not losing weight as fast as I could be, but I've found a good balance based on my personal activity level and quality of life considerations.
Once I've lost the weight I want to lose, I'll keep on with keto, and just gradually increase+track my carb consumption, until I find the a point where I start to gain weight... then I'll set that as my limit.
