I didn't notice any weight loss for the first 5 weeks or so, although I went by feel not by the scale. I didn't find this way of eating to be difficult to follow at all, though. I'm not in menopause but I had a hysterectomy (without the oophrectomy) when I was 39. I know that I will never look like a hot young bikini babe or a cross-fit babe but I'm pretty satisfied with my more athletic and strong physique and the ability to eat for realz and not gain weight.
