Please don't forget that the main reason you believe that it is healthy to eat lots of fruit and vegetables , low fat and plenty of fibre, is precisely because that is what you have been told for years. The very same years when everyone got fat and ill.
As a result of that advice a couple of things have happened :
People do not generally like " fruit" - what they do like is " sugar" - the result is that most " fruit" we are now sold bears no relation to the fruit of our ancestors - instead it has been engineered to become a sugar bomb - these pictures illustrate the point

The same is also true of many vegetables - for example recent adverts about bird's eye peas -" the sweetest yet" So please don't feel too guilty about reducing your level of fruit and veg. compared to public health messages. These messages do not reflect the changing nature of the fruit and veg.
Vilification of red mea
Low fat -, low sat fat -little red meat we have been taught about this for so long its hard to get one's head around it at all . Its important to understand that actually most of this bears very little relation to the actual content of foods - for example see an analysis of red meat below .
Initially you will feel that the diet is very restrictive , that's inevitable when one is cutting out the vast majoirty of the stuff for sale in supermarkets, however if you do have a go at the dietdoctor.com recipes ( or those available here) there are certainly some lovely recipes to try.
good luck
