Hi Olivia!! It truly did for sure the first week. I was very into the whole meal planning and went to the supermarket to get all the items I needed for an entire week. It worked well, if you have the time is really the best way to go. We have been doing this diet for 3 weeks and today starting the 4th week. Now we don’t plan as much given that we keep the types of things we need in the refrigerator and freezer.
