Picking up takeout is always the easiest option. Yes, the actual cooking of the meal does not take too long. The problem is putting the thought into what to prepare, purchasing all the ingredients and then actually preparing the food.
I prepare a lunchbox on a daily basis which generally has the following: plain/greek yogurt with nuts and a tsp of honey, 2 x fruits, 20g of biltong, a salad with some protein source and carrots/cucumbers/celery to keep hunger at bay (I get my ideas from Pinterest). I will have two cups of coffee a day with stevia. Dinner is generally a recipe I find adapted for a calorie / clean diet. All of that takes time and effort especially when working long hours and then trying to get in training. I don't even want to imagine how parents get it all done.
My diet is very low in calories, and full of fresh foods. For others that are not restricting calories or need more protein, I am sure putting together daily meals takes quite a bit more effort.
seanyp00h, I am trying to get around 100g of protein a day. Not even getting close.
