Hello Rascal, welcome to the Forum. Although your blood sugar was very high when you were diagnosed, you have done remarkably well on the metformin. Losing the weight will help very much in controlling blood sugar. Please read our stickies at the top of the Diabetes Forum here for more information about
diet and blood sugar levels. Also, the following website has a lot of information about
diabetes:

Basically, carbohydrates will raise your blood sugar. Staying away from potatoes, bread, cereal, rice anything made with sugar and flour will help keep blood sugar lower. Vegetables (except the root vegetables), salad greens, nuts, most beans, lean meats, fish chicken are what you should be eating. If you keep a daily food journal of what you eat at meals and what your blood sugar is about 2 hours after eating, you will see what effects that food has on your blood sugar. It's best to keep blood sugar lower but this magic number varies from doctor to doctor and professional organization, etc. In my opinion, I think keeping it under 120 in postprandial readings (after eating) is best.
Exercise helps keep blood sugar lower too - and, of course, exercise benefits your heart, circulation, lungs, everything! Even your mood!
My experience with the nutrition/food classes was difficult because they are trained to tell you to continue to eat whole grains. For me this is counter-productive. This means that you are eating the very food that raises the blood sugar and this doesn't make sense to me. There is no nutrition in whole grain food that you can't find in a diet of leafy greens, vegetables, some fruit, proteins, etc. This is my personal choice.
Please do some poking around on our Forum for threads that talk about food, too. And ask questions. We have many members who are happy to help!
