Hehe, your requirements are very high. Generally speaking, it is difficult to achieve the effect of 25 kg in two months. But I still offer you some methods. As for whether it has achieved results, there is no guarantee.

Exercise: swimming, high-temperature yoga, aerobic exercise: running in the morning and walking slowly at night (at least half an hour, sweating is effective)

Diet: Eat more fruits and vegetables, eat less fat, eat three meals normally, be full at 7 or 8 minutes, eat less or not at night, and refuse all snacks except dinner.
