I got an early warning.
Sugar cravings were present from age of two, family members developing T2, 3 babies weighing over 10lbs each even though I was very slim, high fasting blood glucose for past 11 years, several GTTs near limits. I never doubted I would develop T2, but not only found it difficult to be motivated enough to drastically do something about my weight, I didn't have the knowledge of what would work (reducing carbs) till recently when I found this forum.
What did I do in that eleven years? Continued going to gym 3 times a week, and followed the high complex carb diet recommended, but I gained weight and succumbed to constant cravings and hunger. I was confused as to why I couldn't lose weight. Over the years, I had dropped soft drink, icecream, biscuits, cake etc from diet (but not choc) and increased fruit and veg and upped the exercise. I still didn't lose much weight, 100kg down to 95kg, but I do believe it has staved off T2 for quite a few years.
