Diet for people with hypoglycemia. Recently, I have been diagnosed with hypoglycemia. Since I am still in high school, lunch is at a predetermined schedule, meaning it's approximately four to five hours before I eat. For this reason, I have been eating a snack in between classes. The problem is that I have gained about 20 pounds because of this. I'm not one to work out, but I do occasionally. I would like some advice as to what foods I should eat
