I immediately went on a low-carb diet. Back then, it was mostly called the Atkins diet. Today, it's mostly called the Paleo diet. Either way, it's the same concept. Eat mostly natural foods and cut out the added sugar by virtually eliminating all processed "supermarket" foods. As well as all fast food.
20 years later, at age 60, not a trace of diabetes. I'm about 50 pounds lighter. I'm overall in much better physical shape then I was two decades ago.
Some other FReeper posted something like this a while back:
Cows eat grass and are fat. Wolves eat cows and are skinny............
It’s specifically visceral fat that’s the main cause of insulin resistance. Visceral fat physically prevents insulin from binding to sugar molecules.
Good for you!
