Reversing diabetes' usually refers to the case where people with type 2 diabetes are able to restore their blood sugar and insulin to normal levels, such that they no longer need to take medication. This is also known as putting diabetes in remission.
The reversal is not necessarily permanent – to keep diabetes in remission and stay off the meds, you have to keep your weight in the healthy range by continuing to practise healthy eating habits and staying active.
Also, note that this doesn't happen for everyone – while weight loss can be beneficial in reversing diabetes progression, it also depends on how long you've had the disease, how severe it is, and your genes. Some people who are at a healthy weight are living with type 2 diabetes too.
According to Dr Daniel Wai, endocrinologist at Mount Elizabeth Hospital, it is believed that each of us has a definite amount of fat storage capacity. When that capacity is exceeded, the body does not want any more additional fat, and becomes resistant to insulin.
When you develop insulin resistance, there is just no way for your body to convert that sugar to energy. You end up with raised blood sugar levels, and your doctor diagnoses you with type 2 diabetes.
The more body fat you have, the harder it is for your pancreas to make the amount of insulin your body needs to control blood sugar. That's why weight loss – through changes in your diet and physical activity – is especially beneficial in controlling and reversing diabetes progression.
A diet that aims to reverse diabetes would basically mean a diet that helps you manage your body weight while meeting your daily nutritional needs, and may require a calorie adjustment depending on an individual's body composition and condition.
