Thank you all for your very informative responses - I am trying to track my calories purely as I currently don't trust myself and I have allowed myself to get so out of touch with what I am consuming that I need to get some sort of idea of how much.....tracking carbs however is of course my priority and keeping below 20g. I'm on day 5 now though with no change in weight however I have been exercising every day and have started to walk to and from work instead of catching the bus. Ketostix this morning were purple so hopefully I am starting strong.
