Of course not. For healthy people, drinking lemonade can lose weight, but if you lose that much, it will definitely affect your health. 10-20 kg a month should be ok, which requires at least 30 minutes of exercise and reasonable diet during the day. Be sure to have a good breakfast and a full lunch. You can eat less staple food for dinner, eat some vegetables and fruits rich in vitamins every day, and have a proper amount of lemonade at night, which is healthy and can lose weight.
