Any advice for Dieting and exercise for a type 1? I go to legs bums and tums fitness class, and it always decreases my blood sugar. I go to circuit training which is more intense and my blood sugar goes up.. and it doesnt go lower at all later in the day.. (which the doctor said should happen when i go to diabetes clinic) I decrease my insulin before I go because its so intense has anyone experienced that? What type of dieting tips has anyone got? As in meals that fill you up so you dont have to snack throughout the day ( As I do). Im not big i weigh 9st 8 but wanna loose a bit more ready for my summer holiday!
