Every 7700 calories is one kilogram, and the most scientific weight loss speed is 0 per week. 5 kg means you have 3850 calories left in a week, which translates into 550 calories a day. I suggest you take out a special notebook and carefully record your daily calorie consumption and intake. You can lose one kilogram of meat for every 7700 calories, but you can't lose it too fast. If you consume less than 65,438+0,200 calories a day, your body will automatically store energy, because you can't get the energy for basic operation, so your fat will not be consumed.
