So, I've been reading into natural foods that have a low glycemic index...

According to Wikipedia, "Glycemic index is a measure of the effects of carbohydrates on blood sugar levels. Carbohydrates that break down quickly during digestion and release glucose rapidly into the bloodstream have a high GI; carbohydrates that break down more slowly, releasing glucose ore gradually into the bloodstream have a low GI."

Therefore lower glycemic index, the less insulin that is required to process the glucose.

Green beans have a glycemic index of nearly zero, which is awesome. Most of the beans are in a low glycemic range and have a ton of iron and protein, making them acceptable substitute for some of the fattier meat options-- ie: black bean burger instead of a hamburger. Chickpeas can be made into hummus, a great spread for fresh veggies; soybeans, when steamed in the pod and sprinkled with a little sea salt are EXCELLENT, kind of bearing resemblance to popcorn.

****footnote to soybeans....DO NOT under any circumstances plan on dating, snuggling, doing sit ups with a partner, or finding yourself in any enclosed elevator-type situation if you have consumed any more than about 1/2 a cup of these things in one sitting. Whilst tasty and packed with great nutritional attributes, the soybean has a hidden danger..... toxic fumes of sulfuric death... beans, beans, the musical fruit....yes people I said it, awful, terrible, difficult-to-conceal FLATULANCE.
*ahem*
So, if you're hanging out with the guys, or stuck in a car with someone you don't like, snack away and write me all about it. I could use a laugh or two. For the rest of everyone else out there, steamed soybeans are awesome consumed alone or within reason. Soy is also a great option for tofu, cheese, sauce, milk, soy-dogs and lotion.*******

I too am feeling some of the headaches and irritation that come along with starting a new diet and sticking with it. It is painful, as internal organs begin shrinking also to adjust to a lessened work load, and like Jennifer said, your brain is used to being fed this carbohydrate rich buffet, and now it's being told to stick to the salad bar! Ms Brain is protesting loudly. Mine keeps eating its telegrams.
