See here for CKD/Keto information; http://www.bodybuildingdungeon.com/f...enic-diet.html
There is more about carb cycling/timed carbs in one of the sticky threads in the losing weight section. CKD/Keto is all about keeping carbs to an absolute minimum. Carb cycling you have low/medium/high carb days.
If your running different diets/cycles then I'd advise that you post up your questions/routine/diet on here as that's what I did and the information that some of these guys have provided is immense and has really helped me out.
BTW, I'm doing a CKD/Keto diet and eat approximately 160g protein a day, 140g fats and 10-20g of carbs. I do this every day and have one refeed a week. I'm personally trying to push the refeed further and further back until I don't need to do it anymore. Doing it this way I lost 3lbs last week, I'm yet to weigh myself this week though so I'll keep my thread updated with that.
Hope this has been of some help though.
