During the weight loss process, many people often use whether there is a change in weight as a judgment criterion or basis, which is not entirely correct.
Why is that?
1
First of all
Because in the main composition of the human body, besides bones, there is fat and muscle. The density of muscle is greater than the density of fat, meaning that the volume of the same weight of muscle is smaller than fat. This means that, for example, during strength training in a short period of time, muscle mass increases while fat is burned, leading to a more even distribution of body fat, a more slender and lean body shape, creating a visual “lean” feeling. However, the weight may not have changed. Many people wonder “why do I look thinner but my weight hasn’t changed.” In fact, this is a good phenomenon. Therefore, it is recommended in such situations to evaluate the changes in body fat content through body fat percentage testing.

Secondly
Changes in body water distribution. For example, through exercise that promotes blood circulation and metabolism, excess water in the body may be eliminated, reducing body swelling and improving body shape, but weight may not significantly decrease.
Most of the individuals who have a noticeable short-term weight loss are likely to have achieved it through dieting. Dieting means a significant reduction in calorie intake. When the body expends more calories than it consumes, it utilizes stored energy, including glycogen, fat, and proteins, leading to weight loss. However, this type of weight loss is not healthy or sustainable. Overly restrictive dieting in the short term can lead to issues such as imbalanced nutrition, slowed metabolism, decreased immunity, etc. Once normal eating is resumed, weight can easily bounce back, and may even surpass previous levels.
Reminder
Therefore, body weight alone is not the sole indicator of body changes. It is important to consider various body indicators, such as body mass index (BMI), body fat percentage, waist circumference, body dimensions (such as upper arm, hip, thigh circumference), muscle strength, etc. Weight loss is not an overnight process. It is crucial to adhere to a concept of balanced diet, follow the principles of scientific exercise, and persevere consistently in order to achieve a healthy and strong physique!
