Well overall its pretty good, and I am enjoying it. It can be a bit of a PITA remembering to take everything to work each day, probably once a week I have been forgetting to take something. Bit expensive, for the 1800calorie plan, breakfast, lunch and dinner its about $160.
I've been doing it for a month now, and apart from 1 planned whole day, and 2 planned dinners, I have only strayed from the plan two other times for dinner. So I've had takeaway once in the last month, compared to probably once per week before. Having paid for all the food upfront, and not wanting to waste the money is a big incentive to stick with it.
Its good for controlling portion sizes, because you can't go back for seconds!
Food tastes good, plenty of variety. There has been some things where I have been a bit hesitant to try them, but they usually end up tasting pretty good. Only problem I have with the food is on the days where there is pasta, since I hate pasta.
Oh and I have to add, the first week they stuffed up my delivery, and I had to wait an extra day to start it. Been smooth since then though.
