You can't "turn off" insulin once it's been injected — it's going to work no matter what — so it's important to time and match the amounts of insulin given with the body's needs throughout the day and night. Following a meal plan from day to day and getting regular physical activity will help make it easier for your child to achieve good diabetes control.
If you google “diabetes cure” you are directed to websites like WebMD and the Mayo Clinic where you find information on diet, exercise, medication, and insulin therapy, but nothing about the cure. This lack of information may have to do with the fact that Americans spend $322 billion a year to treat diabetes, $60 billion a year on weight-loss programs, and $124 billion a year on snack foods. This is about 3% of the US economy! Because so many peoples’ livelihoods are supported by diabetes and its main cause, obesity, the viral effect of people getting cured and telling others is greatly diminished.
