it is totally normal with raising morning blood glucose , therefore look after your morning blood glucose if they are in avarage rising then it is time to go even lower carb wise or/and protein wise many times as well
As you have maybe been fasting, then it can also happen the first days of a fast as well as the liver uses its reserves stored for glucose roduction there too... after more days of fasting usually peoples morning numbers get a bit better or even very much better... depends a few has a body that steals proteins from other places in their bodies and changes that into glucose also... then fasting is maybe not their way of going, that is a personal judgement after experience , but one can only be sure after many days of fasting of that.
