The thing I like to look at is how food affects hormones. Carbs are good as they increase leptin sensitivity, upregulate Thyroid hormone, blunt cortisol (to a degree as too high of blood glucose will elevate cortisol levels), and turn off catabolism via the insulin response. Fats BUILD hormones, all the hormones. And we need fats for supporting life. EFA are just that, ESSENTIAL.
In that case, while on a cycle I feel you can "slack" on the fats provided you can shuttle carbs correctly (Genetics).
My diet is very similar to what you outlined but I don't eliminate carbs. I eat what I consider an anti-inflammatory, non anti nutrient diet. So I avoid all gluten, sugar, lectins, and try to have my omega 6:3 ratio at around 4:1.
A TKD would be best I feel in PCT because of the elevated cortisol risks. But after you feel your hormone levels have balanced out you can switch to a CKD. I don't like either of these because I don't think you NEED to be in ketosis to produce adequate energy from fat cells. And I have a hard time producing enough ATP and endurance to do the kind of work I need to for the gym.
If you feel Keto gave you good results I wouldn't see a reason why it wouldn't again.
