I was just about to suggest that!!
Honestly if you want advice on healthy dieting and weight loss I would say head down to your local gymn. Often there might be programs or advice points there (if nothing else leaflets and such) which should be able to give you some constructive starting points and advice.
I'd also say (though it sounds like your not going to but I'll say it anyway

) try not to shock/overtax your system with sudden changes in diet and activity. Any big changes need to really be done with some constructive research so that you will not only achive your end result but also do so in a manner that won't leave you damanging your health in the process
