I suspect you will be able to do similarly with other carb sources.
Reason for increased blood sugar during training (you may already know so just explaining in case it’s of interest to the OP): increased circulating epinephrine, growth hormone, and glucagon all stimulate gluconeogenesis (production of glucose) in the liver, which kicks it out into the bloodstream to prevent a perilous drop in blood sugar as your muscles start to vacuum up what little is in your blood.
