What are the BMI Standards and Ideal Weight Charts for Adult Women and Men?

BMI (Body Mass Index) for adult females is a crucial health indicator, calculated based on height and weight. Specifically, BMI is determined by dividing weight (in kilograms) by the square of height (in meters). For instance, a woman who is 1.65 meters tall and weighs 60 kilograms has a BMI of approximately 23 (60 ÷ 1.65² ≈ 23). Based on BMI, we can categorize adult female's physical condition into the following three categories:

1. Underweight: BMI is less than 18.5, indicating a possible lack of sufficient nutrition to maintain normal physiological functions, requiring increased nutrient intake.
2. Normal: BMI ranges from 18.5 to 24, indicating a relatively healthy physical condition that requires a balanced diet and adequate exercise to maintain.
3. Obese: BMI is greater than 24, suggesting excessive fat accumulation that poses potential health risks, necessitating measures such as dietary changes and increased exercise to control weight.

Male BMI standards and adjustment methods:

1. Normal Range: Male BMI falls within 18.5-23.9 kg/m², with significant individual differences that can be calculated based on personal height and weight.
2. Influencing Factors: Height and weight are influenced by various factors, including genetics, exercise, and nutritional intake.
3. Adjustment Methods: A BMI above the normal range is often due to excess nutrients or insufficient exercise, requiring dietary adjustment and increased physical activity. A BMI below the range is typically caused by malnutrition, requiring increased nutrient intake. If symptoms persist, medical attention may be necessary.

Maintaining a healthy BMI is crucial for both adult males and females. A high BMI can increase the risk of diabetes, hypertension, heart disease, and other illnesses, while a low BMI may lead to malnutrition and weakened immunity. It is recommended that women regularly measure their height and weight and calculate their BMI. If the BMI falls outside the normal range, prompt measures should be taken to adjust dietary and exercise habits to maintain a healthy physical condition.

Normal female weight: Standard weight ± 10%.

• Overweight: More than 10% but less than 20% above the standard weight.
• Slight obesity: More than 20% but less than 30% above the standard weight.
• Moderate obesity: More than 30% but less than 50% above the standard weight.
• Severe obesity: More than 50% above the standard weight.

The formula for calculating standard female weight is: Weight (kg) = Height (cm) - 100. A fluctuation of about 10% above or below this value is considered normal.
