Specific implementation: the first day: apple 1 kg. On this day, you can only eat apples, eat nothing and drink water all day. Apples should be eaten slowly in small bites. The next day: 1000 ml yogurt or skim milk, divided into six or seven equal portions, one portion at a time, only drinking milk all day, and not eating others. If you are thirsty, you can use milk instead of water, or drink milk and yogurt at the same time, but pay attention to the amount. The most important thing to lose weight is persistence, come on! I wish you success in losing weight!
