What if i miss my time eating frame?

I have a question regarding protocol. I am a nurse and I get so busy some days I do not get to eat until late in the day if at all. I have my lunches already pre-planned/made but miss my protocol window for my second meal/lunch (10-2). Some days when I finally get my lunch I’m not even hungry because I am so stressed from the work day but I feel that I need to eat so I’m not starving for dinnertime. Do I still eat even if I’m not hungry to prevent hunger later? I realize there is always enough food but mentally knowing I won’t be eating until 10 am the next day triggers my scarcity mentality.
