Flavor does not matter, presentation does not matter but the food shouldn’t make you sick, and should ideally have enough calories per day for the average person to survive (2000 kcal min).
Edit: I am not in any danger of starving or malnutrition, nor am I insolvent. I’m mainly asking this question out of curiosity on how people would approach a solution :)
Im a 180lb male and my maintenance calories is 2687. I do 1hr lifting 5 days a week but am pretty idle besides that.
2000 is really low for men.
