As far as I know, some friends have eaten other food substitutes. But after trying it, it seems that there is no weight loss effect. Some tastes good and full, but they haven't lost weight after eating for a few days. Some products don't feel nutritious enough, but they do have a weight loss effect, and they will rebound as soon as they stop. So I tried Avon Golden Triangle, which was more nutritious and healthy. He has whey protein, red yeast capsules, and slimming nutritious meal packages, and the nutritional mix is more reasonable. The most important thing is that it only takes 25 days to have an effect, and it will not rebound.
