Just be careful with hypoglycemia.
I wouldn't think it would help so much with glycogen depletion, as some of the actives shuttle glucose into muscle tissue to be stored as glycogen. By lowering glucose substrates in the bloodstream, this would likely help with ketosis; moreover, the drop in blood glucose independent of the insulin receptor will certainly help with insulin sensitivity.
Big word of caution, as mentioned above, is the hypoglycemia. Light to medium intensity cardio would be a good way to go.
