The reason why milkshakes rebound is that your eating habits and living habits have not changed. Milkshake itself can lose weight, because it contains protein, which can enhance satiety. For example, the protein content of Qiandong milkshake is as high as 40%, and the satiety lasts for 4-5 hours, so it can replace meals to lose weight. But if you can't control your mouth and still eat and drink, it's useless to do anything.
