As a nutritionist, I can suggest you some dietary modifications which might be of some help. Since, your body is producing too much insulin, I would advise you to change the type of carbohydrates which you are consuming. Avoid refined starchy foods like white rice, white flour or self-raising flour, semolina, pasta and noodles made out of refined flour, potatoes and other roots vegetables, and simple sugars which you will mostly find in glucose, sweetened beverages, fruit juices, soft drinks (not diet drinks), refined sugar (sucrose), sweets, jellies, jams, candies, bakery items like cakes, pastries, chocolates etc. These foods contain alot of sugar which causes sudden increase in blood glucose levels leading to secretion of insulin in large amounts. Instead choose complex carbohydrates like whole grain cereals like brown rice, whole wheat flour products, broken wheat porridges, oats porridge , oat bran and other bran rich foods. Choose whole fruits like apples, guava, peaches, plums, etc and vegetables as raw salads which will help in preventing reactive hypoglycemia. Include plenty of fibre in all your meals to prevent blood sugar from rising too quickly. This helps to avoid sugar rush/sugar crash syndrome which is commonly seen in reactive hypoglycemia. Read labels to avoid foods which have a low fibre and a high sugar content( sucrose, glucose, maltose in malted foods and drinks). A high fibre diet will not only prevent blood sugar spikes but also help you to control your weight. Hope this answers your query satisfactorily.
