Hi there . . .
Getting some of the weight off will go a long, long way to correcting your problems. The experts say that even losing 10% of your current weight will help your blood sugar control. Take a look at some of the "Stickies" at the top of the forum for links to various helpful sights.
BTW, "low-carb" is not necessarily a plan for diabetes control. It's far more important to choose "good" carbs (vegetables, fruits, whole grains -- rather than highly refined carbs like white bread and sugar) and to "balance your carb intake" fairly evenly throughout the day in order to stabalize your blood sugar levels as much as possible.
Good luck on the journey to better health and fitness, Chickie. Keep up the good work you are definitely on the right track with the diet and exercise.
