Oh - it was a while ago and the memory is not what it was - they were a well established slimming organisation.

I think their origins were in 'the Cambridge diet' - that goes back many decades now.

I did some work on that when I was with Lyons Tetley, later Allied Lyons - I quite liked the products, but they were equivalent to 30 gm of carbs in each sachet - three of those in a day and I did not lose any weight.
