| Could be some form of the dawn effect dumping glucose according to internal rhythms coinciding with your walking. Or you could be starving your system for energy which could also cause the liver to dump glycogen.
Test:
You might try slicing up an apple and eating a few slices before you start and a few more while you walk. If that works, it isn't a dawn thing.
