My dad is a diabetic, but it is a holiday.  How much cake can he eat today?

On special occasions, it is OK for a diabetic to eat more than usual. Your dad could eat some cake as long as it is in moderation and not too many carbohydrates. You can consult his doctor to decide how much cake he can have based on his daily carbohydrate intake limits.
