Hi,
depending how long you have had diabetes, and your overall condition,
losing weight and changing your diet to a strict low carb diet / keto diet, could possibly put your diabetes into remission or at worst make it very much easier to manage.
The principle of low carb diet is restricting carbs, particularly all grains, sugars, starchy veges and sweet fruits, and eating a diet that focusses more on protein, low carb plant foods (veges and non-sweet fruits), some nuts, and healthy fats.
