Diabetes and weight loss: They're the yin and yang of optimal health. There's no question about it: If you're overweight and have type 2 diabetes, dropping pounds lowers your blood sugar, improves your health, and helps you feel better.
Don White, 68, a retired science teacher from upstate New York, first suspected he had type 2 diabetes when he was 45 years old and his school held a health fair for students and teachers. A simple prick of his finger to test for high blood sugar -- a sign of diabetes -- revealed some unexpected news.
