Firstly I'm no Nutrirtionist, so I could be wrong.
I was under the impression bread, potatos, and pasta are in themselves not fattening to any great degree. They are mainly starch and carbohydrates, not fat and sugars. They should be part of a healthy diet.
I am impressed that some of you have actually completly changed your diet - it takes a lot of will power. At the end of the day, you are only going to lose weight my reducing your calorie intake, and then try to burn off more than you consume. If however by changing your diet, you are constantly denying yourself the foods you are used to and enjoy, I believe you are doomed to failure.
I enjoy a wide range of foods, but you will never persuade me to live off oily fish and vegetables, or to jog 10 miles everyday through polluted city streets. Nor will I be going on some trendy diet, that results in someone, somewhere growing fat on my hard earned cash.
Everyone's metabolism is different, I know how much junk I can eat and get away with, I don't need someone to tell me what I should be eating. A little bit of common-sense goes a long way.
Ranting aside....
The link below has some good advice, and his website I find fasinating.

If anyone ones interested I'm 6ft and medium build. My weight varies according to the seasons. I get fatter in winter. My weight ranges from around 168 pounds to 155. I'm happy with that
