Diagnosed as LADA or Type 1.5 diabetic in April.
I wasn't obese, but a little overweight (5'7 and 13st ish), exercised regularly (cycling over 100 miles a week, every week) and not a drinker or drinking fizzy/sugary stuff.
Diet was fine mostly but ate loads of dried fruit and tended to have ready meals when I was working a night shift.
started weeing all the time, went to GP, BM (blood sugar) of over 30. averaging 26.9 from prev 3 months.
After then I cut my carbs as much as I can but not 100% as I'm fine still eating some.
Came off medication after 2 months, diet controlled ever since.
I'd say the best thing to do is actually look at what you're eating and the amounts you are eating.
So many things have sugar (and lots of it) when you wouldn't expect it. Think breakfast and lunch in particular.
Things like meal deals, sammich, a bar and a drink? easy to make that 50-60G of sugar never mind total carbs.
I'm now sub 12st, feeling much better now and Dr says blood sugar average is a bit low (which I feel is good but he says not).
Best advise?
Read the labels.
Think before you eat, fruit/juice/squash etc are going to contain sugar even if it IS fructose.
Don't go nuts or you'll go hypo and crash.
