OK - I don't consider this cheating because I stayed within my 20g of carbs a day and I knew these food choices weren't "bad" ones (as they are allowed on OWL) but I found that 1oz of nuts a day and my low carb protein shake made with water and 15ml of cream got me thru induction. I lost about 6pds (3kg) on induction (only need to lose another 6-10pds more - currently weigh 143pds and aiming for about 134pds) so I don't think this slight variation interfered any.
*FOR ME* I found that tailoring a little worked, without disrupting the process and point of induction. I also recall reading in Atkins' book that it is possible to skip induction (ie for vegetarians) so overall, I don't feel my induction "variations" were too much of an issue.
Anyway - not saying everyone should do it but that's what worked for me - YMMV!!!!!!!
