About 8 months. I ran a 'cleaner' version of the Anabolic Diet (basically a CKD). The fullness returned on the weekends, when I was allowed a carb-refeed day. If you not taking in carbs, you will burn through your muscles glycogen stores, hence the flat look. It will not replenish it fully without eating some carbs, which is why I think targeted keto diet or just low(er) carbs is a better option. There's a lot of good read out there on carb back-loading, or just eating them around workouts. The basis is that while insulin is low, glucagon is high, which means your burning fat for energy. Then you up the insulin around workout times via carbs. Doesn't have to be a lot, 50g pre & post is more than enough for most lifters with a day desk job.
There are a lot of good lower carb options out there.
Targeted Keto Diet - carbs around workout only
Cyclical keto diet - carb refeed day once a week (usually a weekend day)
Carb back-load - carbs only AFTER workout
Ketosis is not really needed on any of these, keeping control of insulin is what is important.
