Thanks for the advice - I weighed myself last night and the weight is starting to shift - not massive amounts but 2 kg gone so that's a start and I have noticed that my trousers are def getting looser.
I am curious as to why so many people say that the calories I am using are inaccurate though? Surely calories burned are a mathematical equation? My HR monitor takes into account my gender, weight, height, resting HR and vo2 max so how can people say this is widly inaccurate? Surely this has got to be more accurate than trying to say so many calories per mile which does not take into account the weight, gender, exhertion or fitness level of the cyclist?
With regards to saying I am eating too much - I put the thread up as I have successfully lost weight in the past (over 6 stone). I then re-gained some and lost that by burning 6000 cals a week through exercise (according to my HR monitor) and eating between 1600 - 2000 calories a day (1600 in the week, 2000 at the weekend). I was disheartened at first as I thought I would lose weight as before immediately but guess I had just forgotten how much muscle I would be building initially.
The caveman diet is interesting but to be honest far too expensive for me to try so I am happy to keep doing what I am doing for now - my mileage is building nicely (I managed 500 miles in the first 4 weeks of having the bike and this should increase as I know that I can now do 70 mile rides comfortably and my average speed is increasing too).
