Losing weight has a lot to do with calorie intake and calorie consumption. When the intake of calories is less than the consumption of calories, the insufficient calories will decompose the body fat to supplement. After a period of time, the body will naturally lose weight. Therefore, to control the total calorie intake throughout the day, it is not helpful to lose weight by relying on a certain food or a certain type of food. Bitter gourd, cucumber, apple and celery juice can't lose weight.
