I have not actually tried the Fat Fast myself, but have had some success with KISSing (Keep it Simple). I recently lost 10lbs after 2 weeks on a KISS challenge after having spent months bouncing up and down with the same couple of pounds.

KISSing is low carbing stripped right down to the basics, and by following it, you remove any foods that your body may be intolerant of, or that may cause even your weight loss to stall. Very often we don't realise that some foods may be affecting us in such a negative way, especially as we have usually been losing weight whilst eating them. However, there does come a time when our bodies rebel and by KISSing we can usually sort this out.

Just thought that you might appreciate some more 'food for thought', so to speak, and if you want to take it further, I've linked to a couple of good KISSing sites.

There is also a KISS challenge for June, if you want to join with a support group.
