my husband did the CSIRO diet last year, and he did loose 10kg in the 12 weeks. He has since put it all back on and then some.

The first week of doing it though cost us $400 in shopping as we had none of the spices or pantry items they were wanting to had to stock up on EVERYTHING. We followed their menu plans 'cept for fish as I don't do fish.

We have both books on it so would alternate between the two if there was a menu that didn't appeal to us that night.
