Let's say that for whatever reason you failed to control your symptoms and you're having an hypoglycemic crisis. In other words your sight is disturbed, your head is numb, your thoughts are becoming negative and you feel anxious and like approaching a panic attack, you're cold sweating and breathing heavy.
We all know that when this happens people or doctors who don't know any better suggests to feed the hypoglycemic person sugar. They give you to tell you to eat water and sugar, or a sugar lump, or a tablespoon of honey or if they're less hard-core a glass of orange juice. That would stop the symptoms immediately but would trigger their returning very soon and making them more intense the next time.
So what a person with an hypoglycemic crisis should eat to stabilize slowly the sugar, recover from the crisis and prevent its returning in the next hours?
That's not true. The fact is that everything is converted to glucose, protein and fat are slower, that's it. You shouldn't use carbohydrates because you want to stop your body from overreacting. The only way it can do that is have a moderate, but well maintained level of carbohydrates for a long period of time, then you can add stuff later.
