Don't think about losing weight quickly, because thin people will rebound quickly, so you must eat dinner, otherwise your body nutrition will not keep up. I prefer soybean milk for breakfast. It's good for my health and I can lose weight. Eat lunch properly every day, don't be too full, eat more fruits and vegetables, and don't be too greasy. Replace dinner with fruit, drink more water and exercise more at ordinary times. You need a skipping rope and a heavy hula hoop as your exercise tools.
