Ive started eating the same thing for breakfast and lunch every single day and supper is my wildcard that changes every day. I also have standard snacks that I have in hand that doesn’t change (like apples and grapes). To be clear, I am not a dietitian, and I’m not positive this is particularly healthy, though I do try to make my breakfast and lunch as healthy as possible I’ve found be streamlining those two meals has really cuts down on my decision fatigue and so I feel less burnt out only having to plan for the next week of suppers. It also has made me enjoy deviations from my routine much more, like when eating out. I go grocery shopping every Tuesday after work. Shopping weekly, but not on Saturday or another popular day helps avoid the crowd AND Monday is when my grocery store gets it’s weekly shipment, so everything is fresh and lasts all week. I hope this helps!
