Okay, let me try to phrase this.
I understand that high carbs + high fats are absolutely a no no, because an insulin spike from the carbs will cause the fats to be dragged with it and stored as body fat.
And if your liver and glycogen stores are full, all extra carbs will be stored as fats.
But if you train hard several times a week the carbs will not be stored as fats because they will be used solely for replenishing your glycogen.
I have some more but that's it for now!
