BBC diet test
Have a look at "BBC what's the right diet for you" website. Do the test on there (its only about 10 questions) and it will guide you to a suitable diet, depending on your result. It says I am a "feaster" (I am a bit greedy tbh! ) and advises a high protein, low GI diet. It also has usefull recipes and helpful advice and science stuff to explain it all. Give it a go and let us know your results.
