If you're not losing bodyfat, you aren't under eating. You may, however, be making poor food choices. How much have you read about diet on this site? Do you count your macros? Do you have a diet you're actually following? I'm trying to gauge how much effort you've put in to losing fat.
I would also suggest starting a thread in the nutrition section of this website. Don't answer these questions here, start a new thread and tag me.
One final thing: I can guarantee you that the OP here did not have bulking and cutting phases in the 8 month period of his transformation. I would be he was shedding fat and gaining lean muscle simultaneously. Either that, or he lost the fat quickly, and then started putting on new muscle following that without 'bulking', just staying lean.
