Sorry to hear you didn’t see much impact from the significant efforts you have made so far.
Cutting out those sweet and sugary things will certainly help, but part of how effective that can be will depend on how many of those things you were eating, and how frequently.
As a next step you may want to consider looking at portion sizes of more starchy carbohydrates in your meals. The modern Western diet can figure fairly heavily with starchy carbs - which is fine is you have a fully functioning metabolism, but once your body starts to struggle a little, it can benefit from some portion reductions, swaps and alternatives.
At a level of 45mmol/mol it’s likely that there’s no need to “throw the baby out with the bathwater”, but some tweaks, changes and choosing slightly different proportions of foods on your plate could help a great deal.
Many find it helpful to keep a food diary for a week or two, noting down everything you eat and drink, along with a reasonable estimate of the total carbohydrate content (rather than “of which sugars”). It might feel like a bit of a faff, and will involve some squinting at packets, and perhaps getting out weighing scales, but seeing which meals are your “big hitters” can really help.
