Yep. Turn into fat instead of store in glycogen muscle. IF there an excess in blood stream. It not gonna line up at the glycogen door and wait for insulin to bring it to the store. It gonna snatch away and to lipid store (Fat welcome house).
And Fat have unlimited store so be careful what you eat. Not all carbs will go to glycogen store. Some go lipid, some burn off, some will get in glycogen.
Generally, body tend to adapt and train to use what you eat. In this case you ingest carb, body use carb for energy for the most.
