Hiya. Personally, I'd give the low carb a try, plenty of testing to start with! Fruit pushes sugars up, berries are usually the least harmful but test and see what affects you. Less root veg, more green stuff, cauli, cabbage, spring greens, broccoli..
If I could advise you to do one thing, it's drop bread out of your diet. You may be able to get away with it, but I very much doubt it! Don't be afraid of meat or fish, any type, just not wrapped in breadcrumbs or batter. Eggs, cheese, all good. Your best friend is your meter, try cutting your spuds, pasta, rice etc by half to begin with, replace with veg or salad. It's not a starvation diet and of course, results will be individual to you, but these are good ways to get acclimatised! Hope that helps, have a look at the low carb diet section too xx
