I tried it very well. If you really only eat breakfast and then eat nothing, you will lose 20 pounds. If you are hungry before four o'clock, you can eat an apple, and you won't be too hungry in a few days. Don't drink milk after breakfast, drink unsweetened soy milk lemonade. If you really stick to it, the effect will be immediate, but your menstrual color will get worse. It won't be too serious, but your period will be normal after eating normally. This is the most vicious and effective way to lose weight. Make up your mind to stick to it and you will be satisfied.
