Roxy - we've all came to our own conclusions about his after our own research. You'll find many posts on this very forum (some by me!), that demonstrate the cycle:
Insulin production > weight gain > insulin resistance > insulin production > weight gain > insulin resistance, etc, etc...
Sugar/carbohydrate makes you fat, not fatty foods. Actually, INSULIN makes you fat, and its the consumption of carbs/sugar that makes the body produce more insulin... The release of insulin in the presence of insulin resistance makes you MORE hungry, so you eat more, and more insulin gets released into your insulin resistant system.
I firmly believe that diabetes (or even pre-diabetes as they're calling it now) leads to weight gain, increasing insulin resistance, leading to more weight gain. When you mody mass (weight) reaches a level when your insulin production and insulin sensitivity are completely out of balance, T2 Diabetes occurs.
We're not naturally greedy people. Insulin makes you hungry. It's very hard to not eat when your blood is being pumped full of stuff that makes you ravenously hungry! Non-T2 Diabetics can't understand this.
Some T2 diabetics can't even understand this!
That's because there are many kinds of T2's. Some can make insulin, but not enough. These people won't know "the hunger" ( :wink: ) like we do. Their insulin sensitivity is such that they CAN use the insulin they produce, as well as any extra that they might need to inject. Then there are those that can produce insulin, but have such high insulin resistance that their bodies CAN'T use the insulin. These are the ones that suffer weight gain - their OWN BODY produces the thing that makes them fat (insulin), and continues to create it when the body doesn't use it as it's supposed to.
Please don't feel guilty that over eating caused diabetes. It's far more likely that diabetes has caused you to overeat!
