As folks have indicated, lower carbs is the way to go.
I've cut out refined sugars (except for the odd square of dark chocolate)
I have very little starchy carbs, i.e. two small spuds on a sunday dinner, low carb rolls from lidl, low carb pasta and tortilla wraps.
The only fruit i eat are apples, i've tested against my meter and apples are ok. i don't like citrus fruit so no loss there but i do miss bananas.
Breakfast is a toasted Lidl High Protein roll in combo with one or more of Gouda slices, salami, high meat content sausages, bacon, eggs (scrambled, poached, boiled) etc
Lunches are pretty much standard salads with chicken, ham or cheese with Mayo or my wife's sugar free mustard salad dressing (a bit like honey mustard dressing)
Dinners are mostly steak, gammon, chicken, pork with either salad or fresh green veg. Mashed Cauliflower with a bit of english mustard is a favourite too.
Homemade trifles are a regular evening treat, sugar free jelly, custard made from custard powder not out of a tim topped with clotted cream. Occasionally i have some grated dark chocolate top too.
We recently had chicken fajitas. Low carb wraps, fresh chicken, sliced peppers and the lowest sugar content fajita mix we could find. consumed with 2 bottles of Corrs lager and was only 1.2 points up on my meter after 2 hours.
I'm ok with Carrots and Peas although some people find these can spike them. I'm even ok with a bag of Walkers French Fries as part of my lunch with a salad.
I've found i can have two or three bottles of Coors Lite lager once or twice a week with no discernible affect on my BG
Coors Lite is much lower carb than other beers.
it really is trial and error with your meter within the guidelines of low carbs, (almost) no refined sugar, very few starchy carbs.
lots of brilliant info and help on this forum, get stuck in and read, read, read.
