Some of the replies seem a bit harsh. If you're very overweight or have other health issues, plenty about you is broken. Temporarily using a crutch to get through the worst of it doesn't seem so bad, if that crutch helps you eliminate sugar. To me, sugar has always seemed kind of drug-like in its appeal. I know that probably sounds ridiculous to anyone who has never had such an addiction, but I'm sure the feelings are real to the person who reacts that way. My suspicion is that YogaBare has probably tried "willpower" before with no luck.
Unfortunately, during a low blood sugar event -- which always felt to me like a deep depression -- a burst of sugar DOES make you feel better. Physically, emotionally, and quickly. That's a powerful association to break, that the taste of sugar is almost immediately followed by relief. It takes several hours before you pay for the sugar by feeling crappy again, and perhaps many years before diabetes and other diseases set in, so the negatives just don't seem to stick as well as the immediate good feelings.
YogaBare, it took me right around two weeks of relatively low carb eating before I noticed a dramatic change in my hypoglycemia: for me it was sudden and dramatic, like someone turning on the lights. And that was back in the days when low fat was all the rage, so I didn't have other wonderful things like bacon to exercise the pleasure centers of the brain. Good luck!
