weight
Weight refers to the weight of a person or an object. It is usually used to measure a person's health and body shape. Whether the weight is appropriate or not is related to the height, age, sex and physique of the individual.
Different people have different requirements for weight. Being overweight or underweight may have adverse effects on health. Therefore, it is very important to know your weight and take appropriate measures to maintain a healthy weight.
Factors affecting weight
The change of weight is influenced by many factors. Eating habits are one of the most important factors. Excessive intake of high-calorie and high-fat foods will lead to weight gain, while insufficient intake of low-calorie and low-fat foods will lead to weight loss.
In addition, the increase or decrease of exercise will also have an impact on weight. Moderate exercise helps to consume energy in the body, promote metabolism, and help maintain a healthy weight. Lack of exercise can easily lead to weight gain.
A healthy weight range
According to the standards of the World Health Organization, weight can be estimated by calculating body mass index (BMI). Body mass index is a numerical value calculated according to the height-to-weight ratio. For adults, the body mass index between 18.5 and 24.9 is considered as the normal range. Below 18.5 is considered underweight, and above 24.9 is considered overweight.
Over 30 is considered obese. However, the body mass index (BMI) is only a rough index, which cannot fully reflect the body fat content and muscle mass of individuals. Therefore, other factors such as waist circumference and body fat rate need to be considered.
Ways to maintain a healthy weight
In order to maintain a healthy weight, people need to maintain a balanced diet and moderate exercise. In terms of diet, you should choose nutritious foods, such as vegetables, fruits, whole grains, protein and healthy fats. Avoid eating too much sugar and saturated fat. In addition, it is also important to control food intake.
Moderate exercise helps to consume excess energy, increase muscle mass and improve metabolic rate. Do at least 30 minutes of aerobic exercise every day, such as brisk walking, running and swimming. In addition, maintaining a good sleep quality and reducing stress are also important for maintaining a healthy weight.
