That's kind of a hard question to answer, Greatdanelady,
A lot of us, when we first start LDL, are eager to lose a lot of weight. Then, when we find how EASY this WOE is, we settle down and just let things take care of themselves. LDL then changes from a "Diet" to a way of life. So many of us no longer refer to LDL as a diet, it has become the way we live. And when what you eat is how you live, you no longer stress about how quickly you're going to lose weight.
Every other "diet" I was ever on was a short term period in my life that I "suffered" through so I could get slim and then get back to eating all the things I have given up in order to go on the "diet". On LDL, there is no sacrifice, no suffering and you eat all you want of every good food. Who would want to give that up?
So, Typically, I don't know how quickly someone loses weight on LDL. We are all so different and each one of us configure LDL to our personal lifestyle that there is really no good answer to that question. I hope you're not more confused now than when you asked the question!
