I'd probably agree on the too few calories, but its hard to tell without knowing what else you are doing. Do you have a weight routine? Other activities? Sit down job or physically demanding one?
Start putting it all into
Fitday do that for a week and then try to reflect on it.
I don't really know about WW personally, but I think there are better programs out there if you are coupleing this with a good weight routine. One thing I noticed though was a lacking in proteins. You've got some good food in there, but is that a profile that you can maintain for months/years?
