Five years ago I was 60 pounds heavier, ate/drank whatever I felt like that wasn’t high in sugar, was sedentary, smoked a pack a day and had to take Metformin to control my blood sugar.
Then one day I experienced chest pains, which turned out to be heart disease. Four clogged arteries, two of which got stents.
I quit smoking, drastically changed my diet (low fat, low salt, low cholesterol, low sugar, whole grains, fruit, vegetables, nuts, ultra-lean meats), took up exercise, lost 60 pounds, and now my A1C is almost always in the low 5’s (5.1 - 5.3), and I am not on Metformin.
My doc says that I have a history of diabetes, though I am not currently diabetic.
