That was a good move, post-workout carbs. I've had a similar experience, perhaps our metabolisms are similar. What is working best for me is this, lifting every other day. High protein (1.5g per lb), low fat from lean meats and fish oils, and no carbs except every fourth day, or after every OTHER workout. I'm taking a min. of 1g per lb, so about 200g carbs after every other workout.
Its a carb cycling diet where I have 3 days low carbs, 1 day high. It works so much better than a regular keto or CKD, at least for me.
