Advertisements are overwhelming. It's expensive. As an ordinary office worker, I can't afford it. I suggest you use Byron Weiss milkshake. Byron Weiss is a nutritional milkshake, which contains natural ingredients such as oats, soybeans and wheat germ, and can provide the nutrition that human beings need every day. Parents are advised to walk1-2km while drinking milkshakes, and lose weight through exercise and meal replacement. Although the effect will not be much thinner at once, it is still a very healthy way to lose weight.
