Well, its more than two weeks... I found it really hard to do, and no significant weight change... I think part of the problem was that I would get home and be tired and hungry and the kids/partner would have dinner organised and it would inevitably involve carbs, and if I was too tired to be bothered I would eat a few carbs.

So this turned out to be a "fewer carbs after 5" diet... and it made no discernable difference.

Maybe I'll try again when I can have more control in the food prep area.
