I posted a comment earlier today describing my own experience. I never said that everybody should stop eating food with added sugar, I just said it worked for me.
One main thing we don't mention in this thread is that sugar is addictive. Cutting sugar was hard like quitting somking was hard. If you never got addicted like I was, I guess it os hard to understand the problem. But when you are addicted it is hard to just know if you are hungry or not. So I choosed to go on the other extreme which works better for me.
