Eating the same thing everyday for weight loss helps with portions and food planning. I do not have to think about what I am going to eat as I have already determined it and as it is more or less the same thing every week with some variations and modifications (and to be honest, with some cheating). Eating the same thing everyday also helps to control how much money is spent on food and also how much food is eaten and helps to eliminate food waste. It is mostly a win- win! The main downside is food-fatigue, and the lack of excitement in eating but otherwise it works pretty well.
