If you have a lot of fat, it is indeed possible to lose two kilograms a day when you start to lose weight, but this will happen in half a month at most, mostly for a few days. At that time, I lost eight kilograms when I weighed myself the next day, and then I gradually lost about 30 kilograms in the first month, which is equivalent to one day 1 kg, so as you said, two kilograms a day is 60 kilograms a month, and I have five around me. If your muscle endurance and toughness are infinite, you can do 2000+ sit-ups every day for a month, and control your diet at the same time, you can lose 60 pounds a month.
