I don't know about others, but I have watched how my father struggled over the last 10-15 years of his life to managed his glucose levels on a low fat, whole grains type diet. Steam fish, lean meat, brown rice, brown rice noodles, lots of veg and "healthy" fruits, milo without sugar...regular hour-long walks in the morning and evening...still ended up with failed kidney, 2nd heart bypass, multiple stents (6 in total), multiple vascular surgeries (3) to save his gangrenous toes. Toe amputations one by one...kidney failure... edema, memory loss etc. Car accident due to hypoglycemia because he likely mis-dosed himself... all the while his HbA1c was around 8% which his doctors assure us is perfectly fine for his age...70+.
What I have gathered from that experience is that many will be falsely assured by the medical community that we have been doing our best. Glucose fluctuation is normal. Chronically high glucose level is acceptable. Diabetes is chronic and progressive. Diabetic complications is inevitable. It is dependent on the luck of the draw. Some have better genetics than others. So just accept it.
But the reality is surprisingly different. Our T2D journey need not be so fraught with challenges when we begin to realize that chronic excessive insulin AND glucose are both damaging. Medication free and Insulin sparing lifestyle is achievable and sustainable.
