This can't be generalized, it depends on your physical condition. If you are just a little high in fat, you can't lose 20-30 pounds a month, and the standard body mass index 10% will lose a few pounds a month;

Obesity is overweight >: 20% can probably weigh more than 5 kg; In the case of high-intensity aerobic training every day.

20%~30% of mild obesity is overweight 10 kg, but if you work hard enough, you can achieve 10+ through diet and effective recovery. After all, your base is not particularly large.

Moderately obese, overweight 30% ~ 50%, 15 kg.

Severe obesity is more than 50% of the standard weight. This can be started from small aerobic exercise and can be reduced by a lot, about 20+ a month. Put it in my hand, hehe, a fat man of 290 who once weighed 160 kg every month.

Morbid obesity and overweight >: 100% This is terrible. If you can't do aerobic exercise right away, you will die. You must take other measures first.

But you can't say you can. See if you are strong or a little weak, for reference only.
