Your diet is way to high in carbohydrates and includes foods you should not be eating whatsoever, especially at the beginning. Here's what's wrong:
1. Avoid all bread at first, doesn't matter what kind.
2. Some people actually do okay with a little brown rice, I say avoid it at first to eliminate all complex carbohydrates other than vegetables, but you can try it.
3. Pie? You're kidding I hope. No pie. That crust will kill you unless you're getting an organic, whole grain crust, which I doubt you are, but even then it's not what you should be eating. Pie must absolutely, without a doubt be totally avoided for a long, long time. I think steevia is okay if you want to try a natural sweetener that won't raise blood sugar (i think it's natural, make sure to check) but i've heard xylitol is the best for that. Eating that pie isn't affecting you at first, but I bet it's causing you problems days down the road, trust me. Unless you eat straight sugar, you will usually not notice any symptoms for a day or so.
4. Bottom line, too many carbohydrates for the day, you should be getting no more than 100g and no less than 60g.
5. The people you're reading that are getting good results in two months or less are on low carbohydrate diets, which in my opinion is the only way to go, carbohydrates are added back in slowly after you get better. Until that time, they must be watched carefully otherwise you'll never get better. I personally don't know anyone, unless they have a more minor form of hypoglycemia or fasting hypoglycemia, who can eat a higher carbohydrate diet with lower protein and fat and get better. Everyone on here has tried that diet and failed, even me. The body has to learn to slowly tolerate a carbohydrate level that you set, very, very slowly.
