Recently, there has been a heated discussion online about a certain actress losing 100 pounds to shoot a new movie. Many netizens have expressed their motivation to work hard and strive to lose weight before spring arrives. Although the weight change of the female lead may be part of the promotion of the new film, the topic of weight loss is always eye-catching and worth discussing. How to successfully lose weight? What are the ways to lose weight? Let's talk about this matter. Before losing weight, the first step is to clarify whether it is necessary to lose weight. Generally, two indicators are considered: body mass index (BMI) and waist circumference. The normal range of adult BMI value should be 18.5-23.9kg/m2. When the BMI value is greater than 23.9, weight loss should be carried out in a timely manner; At the same time, waist circumference is more important than weight. Adult males with a waist circumference of ≥ 90 centimeters and females with a waist circumference of ≥ 85 centimeters belong to abdominal obesity and also require weight loss. Generally speaking, it is recommended that men have a waist circumference of no more than 85 centimeters and a waist to hip ratio of no more than 0.9, while women have a waist circumference of no more than 80 centimeters and a waist to hip ratio of no more than 0.8. Generally speaking, a person weighing over 200 pounds will lose weight much faster than a person weighing 120 pounds. Nevertheless, it is very difficult to lose at least 8 pounds per month and last for more than 10 months. Someone asked, can weight loss be achieved through liposuction? In fact, to achieve an ideal body shape and achieve even weight loss in every part of the body, liposuction is very difficult. Furthermore, the loose skin after liposuction needs to be tightened by pulling, which may not necessarily achieve the original smoothness and tightness for the face and exposed areas. In addition, liposuction for weight loss can reduce subcutaneous fat, but it cannot reduce visceral fat, which is not beneficial for human metabolism. If the original dietary habits are not changed, liposuction will still rebound. Some people also ask, is it possible to have a stomach cut or go on a diet to lose weight? In fact, dieting to lose weight can force the body to gradually adapt to a low energy intake state, causing a significant decrease in energy metabolism levels, leading to fatigue, hair loss, skin deterioration, menstrual disorders, muscle loss, decreased resistance, and may even trigger eating disorders and thyroid dysfunction. Nowadays, food is extremely abundant, and a person may be able to starve for a few days, but it is difficult to sustain hunger for a year. Even if it can be achieved, if one eats the same amount every day for a long time, weight loss will continue to slow down, and extreme situations such as not losing weight even when hungry, and even swelling due to malnutrition may occur. In this state, if you are an actor, it is difficult to work properly, especially when shooting movies related to combat, as each move relies on muscle strength to present. Can a person who is so hungry and wobbly, a person with loose muscles, successfully play a role that requires high muscle strength? Therefore, the most likely method is to lose weight by controlling diet and increasing exercise, which is commonly known as "controlling your mouth and stepping out of your legs.". Generally speaking, overweight and obesity are mainly caused by unhealthy lifestyles such as excessive food intake, lack of fiber in the diet, irregular eating habits, and lack of physical exercise. Genetic, psychological, economic, and cultural factors can also have an impact on obesity. For overweight and obese individuals, it is important to find the right answers
