No, the last thing to advocate for losing weight is fasting. During weight loss, you don't eat any calories, only fruit and vegetable juice, no matter whether eating such a vegetarian diet is harmful to your health. When you finish this devil training, you can't resist the temptation of delicious food and eat more than before. Long-term fasting will make our bodies think it is "famine", and thus take the initiative to enter a state of hunger. You will eat more when you are hungry.
