Losing weight is a long-term process, and losing weight too fast may have a negative impact on the body. It is suggested that you consult a doctor or a professional dietitian before losing weight and make a healthy fat reduction plan that suits you.

Generally speaking, losing 1-2 kg (about 0.5- 1 kg) per week is safe and sustainable. At this rate, the goal of losing 20 kilograms (about 9 kilograms) a month may not be easy to achieve, and it may also pose potential risks to health.

In addition, besides exercise, we need to pay attention to eating habits and lifestyle. If you simply buy some courses and don't really change your living habits, the effect may not be very significant. If you plan to buy related courses, please consult a professional fitness coach first to understand your physical condition and ability, and carry out corresponding fat-reducing exercise training according to the coach's guidance.
