I think the biggest thing is not making any one macro extremely low unless there is a specific reason

I use my weekly training schedule rather than changing macros after every individual workout

When I add more cardio I sometimes need to increase my food intake depending on how much my activity has changed

On more active days I find that adding some extra carbs helps keep my energy steady

I think adjusting portions is easier than completely changing the meal plan every time my routine changes

Irregular meal times do not really bother me as long as I know roughly what I have eaten by the end of the day

I used to eyeball portions but they were never really consistent from one meal to another

As body weight and activity levels change your calorie needs can change too so the original diet may need some tweaking

Missing one meal does not really affect my progress if the rest of the day is consistent
