I know an APP that can help you lose weight. Call the APP. It's a bit like Keep, but the app can check its body fat content, which means it can monitor how much fat has risen in real time and how much it needs to lose according to normal weight. There are nutritious meals on it, and people who want to lose weight can lose weight according to the nutritious meals on it. It is said that the effect is not bad.

I think it is useful and can be adopted.
