Has there been a significant change in weight from 120 pounds to 100 pounds

The degree of weight loss from 120 pounds to 100 pounds varies from person to person, mainly depending on height, body fat percentage, and muscle distribution. For women under 160 centimeters in height, a significant decrease in body fat percentage may result in significant visual differences; Individuals who are over 170 centimeters tall or have high muscle mass may experience relatively small changes. During the process of weight loss, the reduction of fat and the increase in muscle density will jointly affect changes in body shape. From the perspective of body fat percentage, a decrease in body fat percentage for the same body weight will significantly improve body shape. When weight loss is mainly focused on reducing fat, areas such as waist circumference and thigh circumference usually shrink significantly, and facial contours become clearer. The reduction of breast and hip fat in women may lead to changes in cup size, but optimizing the waist to hip ratio will increase the overall proportion. When muscle mass is maintained well, the arms and legs will feel tight, and the decrease in basal metabolic rate will be relatively small. In special circumstances, rapid dieting to lose weight may lead to muscle loss, weight loss but limited body shape changes. Some people have improved their physical condition due to edema, although their weight has only decreased slightly, they appear visibly thin. Individuals with implicit obesity have a higher initial body fat percentage, and their body shape changes after weight loss may exceed expectations. The population with a smaller weight base has a more significant impact on body shape per kilogram of weight change.

During weight loss, it is recommended to maintain muscle mass through strength training and adopt a high protein diet to avoid malnutrition. Controlling the weight loss rate within one percent of body weight per week is more conducive to maintaining the effect of body shape changes. Regular measurement of body circumference can better reflect real changes than simply focusing on weight, and adequate sleep can help reduce fat accumulation. After a stable weight, it takes more than three months for the body to form a new metabolic balance point.
