Can you clarify why you are doing this meal replacement?
Are you trying to lose weight, therefore using the replacement shake so you dont consume more food than you should?
Do you just not have time to make a lunch, so this is easier?
Does going out or food in general not taste how you think it should anymore?
I ask because over the last few years I struggled with weight. I was up to 230, then down to 196, then back to 216 and now to 200. For me, I just love food.
I have been juice fasting for breakfast, lunch and afternoon snack and eating a sensible dinner and this has made all the difference. It was hard to start doing this. It is very hard to do a complete juice fast as we are groomed to eat.
There is a good documentary: "Fat, Sick and Nearly Dead" by Joe Cross. Netflix has it. It is funny and informative.
I know this may not be what you are looking for, just trying to offer another prospective from my own experience.
