Exercise is the best supplement for you.
You need to lay off the crap in your diet.
You need to learn discipline.
I've known a bunch of folks who ARE NO LONGER TYPE II because they got on a digit control program.
Recently, I met at guy at Lifetime Fitness in Flower Mound, Texas, who previously had been 400 pounds, hypertensive, and type II. Now, a year later, he's 300 pounds, not hypertensive, and NOT type 2. (Those who've seen him drudge through it have an appreciation for his efforts.)
Sure, genes can suck, but, you need to fix-up your diet; you need to EXERCISE.
Tell us your HBA1C and your median glucose value.
You need HIIT.
You need muscle.
You need exercise.
Your insulin sensitivity will increase.
Your glycogen uptake will increase.
You'll burn more calories at rest.
Small meals often.
Slow down on your sugar and alcohol.
Cool it on the fattie stuff.
Slow down on the caffeine.
Ditch the tobacco.
In a sentence, with regard to your blood sugar, steady as she goes.
With regard to Type II, no need to have it, and time to get rid of it.
