Hi, my brother is a Diabetic Type 1 and has been for about 10 years. He recently decided to become a vegetarian and we are trying to tell him this isn't smart. He isn't a normal diabetic as he is 6 feet 2 inches in height and only 150 pounds in weight. When he was first diagnosed with it the doctor put him on a higher carb diet to put weight on him. Since he became a vegetarian he is losing more and more weight. Is is smart for a diabetic to not eat meat? What is the best diet for a Type 1 on an insulin pump.
