1. A woman's ideal weight at 40 years old is not a one-size-fits-all number and depends on her height. The same weight can have different effects on individuals of different heights.
2. The Body Mass Index (BMI) is a crucial indicator of whether a person's weight is appropriate. It is calculated by dividing the weight in kilograms by the square of the height in meters.
3. According to China's BMI standards, a BMI below 18.5 is considered underweight, a BMI between 18.5 and 24 is within the normal range, and a BMI above 24 is considered overweight.
4. Another simple calculation method is to subtract 105 from the height in centimeters. For example, a person who is 165cm tall has an ideal weight of 60 kilograms or 120 pounds.
5. Maintaining a weight within the normal range is beneficial for health. Being underweight may indicate malnutrition, while being overweight can increase the risk of hypertension, diabetes, and other diseases.
6. Controlling weight is particularly important for middle-aged and older women. Healthy habits, a balanced diet, and exercise promote vitality and overall health.
7. Individual cases:
- A person who is 1.58 meters tall and weighs 120 pounds may need to pay attention to their relationship with health.
- A person who is 165cm tall and weighs between 116 and 120 pounds may be considered slightly overweight.
- For someone born in 1976, who is now 43 years old, with a height of 165cm and a weight of 50 kilograms, others might think they are too thin and suggest gaining weight appropriately.
- A person who is 158cm tall and weighs 106 pounds might feel it's acceptable.
- At 42 years of age, 160cm tall, and weighing 48 kilograms, one might be considered slightly underweight.
- A person who is 152cm tall and weighs 138 pounds would need their BMI assessed for a proper health evaluation.
- For someone born in 1973, who is 157cm tall and weighs 60 kilograms, their health status would benefit from a BMI evaluation.
