Hi Im a newbie to all of this,I was diagnosed with PreDiabetes about 3 weeks ago. I've taken it upon myself to change my lifestyle by eating healthier, cook more healthier things and take up exercise. I've seen lots of people mention Blood Glucose Test Kits/Machines?? Is this something I should invest in? All I was told by my GP was to lose weight by eating the right things and get some exercise.....so im slightly confused as to how I should go about things. Any help will be much appreciated!
