You're missing out on massive amounts of things your body needs to function. And while I am a Type2, I always gave dextroEnergy with me. I get hypo's, and the sugar drags me out of them in a hurry. But you need vitamin D (salmon for instance), Iron, magnesium, proteine... Those things don't make you fat, they keep your muscles and organs working. You went on a crash diet, and those aren't meant for the long term. There's a thousand places where you can learn about a low carb/high fat or low-low diet, or whatever diet that actually will help to keep you alive...! But check it out NOW. Don't wait three weeks. If you're passing out you need help this instant, and not from the people who set you on this path to begin with. Either from books, online like here, or another proffessional, but scrap the previous "help". Yeah, you lost weight, but there are healthier ways to do that without becoming malnurished and probably deficient in quite a few areas. You've kept this up, meaning you can stick with a diet... Now take a moment to find one that won't kill you. Low carb/ high fat for instance, is meant as a permanent lifestyle, not a crash diet, and is designed to be sustainable. As are many other diets out there. But if you're working out, especially, you need extra iron and proteine, not less... And make sure you have some fast acting sugars with you in case you feel faint. And if you haven't yet, buy a meter. If you're uncomfortable just popping sugar, check the meter; if it's somewhere in the three or lower, pop some sugar in, as that's a hypo. (15 grams usually does it). You've worked hard to take care of yourself, you've just been given potentially lethal advice. Educate yourself, take the reigns... You can do this!
