Most people who go on a weight loss program (do whatever works for you) have a problem with the scale. Partly you do the work, and you want immediate results. Let me paraphrase my Dietitian on this one. No matter what your present weight is, you did not get there overnight, don’t expect to shed it that way.
First, it is not healthy. Losing too fast can have serious medical consequences. Nor is it sustainable. You want to lose that weight for life. Nor are there any magical pills. You have to do the work.
