Considering macros and calorie counts, what exactly would the effect be of eating very little throughout the day, and filling up the rest of your daily caloric needs with some really shitty fast-food if you got everything else you need for that day macro-wise.
I ask because I derailed my meat+rice+veg diet and went to KFC for a meal the other day, and want to know how badly it fucked me over, despite getting all my macros and calories that day.
