It's really unnecessary. If you just want to be symmetrical and slim and don't pursue the backbone of a star supermodel (which is actually unhealthy), you really don't have to be so hard on yourself. If you continue to eat in a certain way, your figure will change. If you want to keep this figure all your life, you have to be hard on yourself all your life. Who wants to do this? There is no vegetable rice, rice, pork belly, Dongpo elbow, ice cream, chocolate and cake. Are you sure you want to abandon these foods that you have loved all your life? At least I don't want to.
In fact, the hard conditions for losing weight are not high. Don't ask you to eat anything, but "eat calories"
