To stay healthy these days I watch my diet-avoid seed oils, processed foods, carbs and eat mostly meat, eggs and cheese. I also get a full blood work up + urinalysis once to twice a year. If you want to avoid prescription drugs for chronic illness, I think it’s better to take charge of your own health rather than rely on a physician. Here are the markers I find most helpful:

HbA1c < 5.7

Fasting glucose < 100

TG/HDL < 2

Triglycerides < 170

Uric acid < 5.6

And waist to hip ratio should be less than .8

Am I missing any?
