I have heard a lot about lying down, and now people are beginning to pursue "lying thin". Look at the labels of their counselors and nutritionists. I want to say that this is entirely possible!

We all know that the human body is in a dynamic balance, which is a process of constant consumption and intake.

If you want to gain weight, it is consumption > intake;

If it is maintained, it is consumption ≈ intake;

If you want to lose weight, it is consumption.
