Obesity ≠ Overweight We often say, “I’ve gained weight recently, three or four pounds heavier”. Because weight reflects our fatness and is very easy to measure, we tend to use it to measure fatness. In fact, this concept is not desirable – weight is affected by many factors, body condition, bone size, muscle proportion, water content, etc., will affect the amount of weight, but can not accurately reflect the body fat and thin. Therefore, we say that obesity ≠ excess weight, weight as the only indicator to measure fat and thin, is very unscientific. Weight loss ≠ weight loss When it comes to weight loss, the scale is often the thing we miss most every day – any small change in the needle becomes the weather vane of our daily mood. But because weight is affected by many factors, weight loss as the purpose of weight loss often leads to a great deviation in our weight loss – the wavering weight affects our confidence and determination to lose weight; the simple pursuit of weight loss leads us to use rapid weight loss methods, and most of these methods are to lose muscle and water, so Weight loss is easy to rebound. So stop relying so much on your scale pointer, sometimes it will also cheat you Oh! So, how do we know if we are fat or thin, and how to test our weight loss effect? Obesity = high fat rate The goal of our weight loss is to eventually have a good shape and a healthy body. Every behavior during weight loss is an effort to achieve this purpose. In terms of body composition, our body is composed of several major parts – bones, internal organs, muscles, water, and fat. Obviously, the first two parts are basically fixed; muscle is the main place of calorie consumption, its reduction will lead to a decline in metabolism, so weight loss can not reduce muscle; water content will change, it is easy to discharge the body and supplement increase; and fat not only has a great impact on our appearance, but also has a great danger to our health, so the fundamental goal of weight loss is: fat loss! Obesity does not refer to excessive weight alone, but to abnormal or excessive fat accumulation. To measure whether you are obese, you can measure the percentage of fat tissue in your body, also known as the adiposity rate. Weight loss = fat loss When we lose weight, using fat percentage as another indicator is a better reflection of our weight loss and whether we are on the right track than simply using weight as the only criterion. It is important to remember that every action you take in weight loss is about fat loss, not weight loss. So some behaviors, such as reducing water, or reducing muscle tissue (muscle is the main place where calories are burned, and reducing muscle is tantamount to suicide in weight loss), are contrary to our goals and even hinder our weight loss. Although the BMI index is not so scientific, bearing a BMI index far above the normal level is definitely obese. Also, post-operative patients must be supplemented with high quality protein. Our goal is to lose fat. Happy New Year to everyone.
