I was told the same thing by my doctor to just eat well and exercise.
With me it was not what I ate that gave me type ll but how I ate.
I eat healthy food but, have to remind myself to eat a breakfast lunch and dinner, along with snacks during the day. I used to eat mainly just dinner. Now I eat at least 3 times daily even if I have to force myself.
I also found out just lately that when you have a bad cold and are not feeling well your sugar can climb higher.
I don't know if this helped or not. Just my two cents. And yes....LOL That was my thought to on life begins at 40 also, unfortunately time stamp for me started at 30. ;-/ LOL
Best of wishes to you.
