How can I best manage my diabetes at home?

The best way to control diabetes is being smart and selecting foods which will keep not only the sugar down, but will also help to control weight gain and decrease cholesterol. This can be approached by changing to a diet with fewer calories and less fat- you can accomplish this by eating more fresh fruit, vegetables, sea food and legumes instead of daily steak and hamburgers.
One should try and eat a healthy diet which derives at least 20-20% daily calories from protein, 30% of less from fat and the rest from carbohydrates. 

One should become a label based shopper and check which foods are sugar and fat free. Some labels even mention which foods are good for the diabetic. Stop wasting money on consultation with dieticians because there is ample free information on cyberspace.
