Dieting with caution

I have Polycystic Ovarian Syndrome which is nothing to play with.  There is a connection to blood pressure, cholesterol, and insulin issues.  I am also a diabetic, which I have been diagnosed with. Today, I have consumed more fruits and vegetables today than I have had in a few days.  I finally realized that I have to be actually cautious with whatever I consume.  I am at an age where it could or will be harder to lose weight.  I have also read, that because of my age, it could improve.  That is good news.  But I wonder if that would be the case even with the poor diet.  Those are questions that I need to ask myself on a daily basis.
