If you insist on not eating after noon, you must never eat at night. Not eating in the afternoon is Sakyamuni's shamanism precept. Buddha believes that people have accumulated a lot of toxins after a night's rest. Detoxification in the morning is far more important than tonic, and you will fall asleep immediately at night. You must keep your body light to sleep well. If you want to skip lunch, you'd better not eat at night. Since you won't feel hungry if you don't eat at night, your body can accept this way, so don't force yourself to eat. I have always strictly abided by the precepts of Shamanism. I drink a large glass of honey water in the morning and eat everything at noon, but I won't eat too much, and all the nutrients will be ingested. Drinking a cup of honey water two hours before going to bed at night, how much you will lose in a month, is hard to say, because there are many other factors, including the speed of your metabolism, the level of your basic metabolism and so on. But if I can keep running, the conservative estimate will not be lower than 10 kg. I have persisted for many years. I am1.66m tall and weigh 88kg (female). Actually, I can be thinner, but I don't exercise. Accustomed to it, it is not only harmful to the body, but also makes the body lighter and accelerates detoxification.
