At my husbands last physical his fasting blood sugar levels were high. They told him he was at the pre-diabetic level, and needed to work on lowering his blood sugar.
The best way for him to do this is to lose some weight and start a regular exercise program. Neither of these things have been easy for him.
He has put off going back to the doctor because he has not lost any weight. I know if he can lose some weight and keep it off, he has a much better chance of having healthy blood sugar levels.
