This is what you HAVE TO DO. I'm training with Mr.X right now, and if you want to do it right you gotta do what he says exactly. Your carb up can be 2 days, but he prefers 1 day. This way you are in ketosis longer so, so you'll burn more fat. Also, doing a one day carb-up helps prevent as much, if any, fat from being stored.
Now as for your training, this is what he reccomends.
Your workouts should be like this: 15 reps, 12, 10, 8, 6, 15 ALL IN A ROW. You should do 2-3 sets like this per body part. Yes its hard but its the quickest way to get your body back into ketosis. You just have to do it if you want the best results.
Day 1(day after carb-up)- Chest and back, 20 min cardio at low intesity right after.
Day 2- Arms, Shoulders, 20 min cardio at low intesity
Day 3- Legs and abs, 20 min cardio at low intesity
Days 4-6- 1 hour of low intesity cardio on an empty stomach. Empty stomach is best, but if you can't, do it when you can.
Day 7- Full body circuit, aim for 30 reps. Do 3-4 rounds. Then immedietly start the carb-up. And yes, the carb powders with a scoop of protein are preferred for the first 2 meals because you need the carbs to be absorbed quickly.
