Why does dieting work well in the early stage and not well in the later stage? My original 148kg 12 days was reduced to 128, and now I have been dieting for almost 60 days, and only the first 20 days have an effect. Losing weight in stages will start to decline rapidly and then stop. At this time, you need to keep your weight. Don't think that you can't lose weight at first sight. Many people get stuck at this stage and then gain weight again, but it depends on what medicine you use to lose weight. It's hard to say, exercise and dieting are better. After this period, you will lose weight.
