Adapting plan to low sugar/carbs needs

Hello everyone, is there any general recommendations or info from people with insulin problems (diabetes, Hypoglycemia, Hyperinsulinimia) to add to the general guidelines? i was diagnosed with Hyperinsulinimia a month ago and have undergone a general change in eating habits as advised by a physician (minimize carbs, minimize sugar consumption when inevitable, taking meds, switching sugar for fructose, up cardio exercising) but in general i have no idea how to fit this with a healthy weight loss program, i saw no stickies or consolidated info on the subject, is there any people here with a similar background that can provide some insight into this process? thanks for the help.
