Biwi I have low carbed on and off for years, did really well some years ago but found it easier to eat 'normally' in the end. There was such a bias against the WOE, also I am not generally in the same office every day, and found it difficult to maintain when travelling.
The thing that made the difference this time, is that I am not dieting to lose weight, I am eating in such a way as to maintain my blood sugar at a good level. Every day I get a reality check on my diet, so I can see if my carbs are creeping, I also know that if I want to go off piste occasionally, I can pull it back by upping fat etc, and the meter will tell me when I am stable again.
The weight is falling off quietly, I am not obsessing about what the scales say every day which is much more healthy.
I have found my blood sugar monitor to be an amazing tool to aid the low carb WOE, much more useful than ketostix. This experience has shown me that the purpose behind eating low carb must be to control blood sugar, therefore reducing the insulin response, therefore preventing the insulin laying down excess carb as body fat.
At last I have a tool that gives me a realistic picture of whether I am eating sensibly!
