I haven't had my operation - I'm at the beginning of this journey. But in my mind I am going to have to change every single eating habit I currently have, including popping food into my mouth - I can't just mindlessly eat. Perhaps that's what was worrying your mom? Maybe it looked to her like you were just mindlessly stuffing food, even though it was small and grilled. She just saw you go through a huge surgery and she (I imagine) wants you to succeed.
