Hi. Your fasting blood level is slightly elevated and I can understand the GP advising a low-GI diet and losing weight. A low-GI diet is good as it smooths absorption but doesn't necessarily reduce your carb intake which is essential if you are overweight and want to get your bloods down a bit. Many of us would certainly say have low-GI but also control you overall carb intake to a level that helps weight loss. You might want to go for something like 150gm/day or whatever level enables you to achieve gradual weight loss. That means avoiding all added sugar and going more for protein, veg and fat rather than carbs. Do read package labels. Control bread, pasta, potato and so on. There are many web-sites that will give GI ratings for a range of foods; just Google low-GI etc. Having a glucose meter will also help you check which foods affect you most.
