If your bones are bigger, there is really no good way to make yourself thinner. For example, Ar Fi, I guess she always looks fleshy because of her big bones, although she is not heavy. At this time, you can make yourself look thinner by wearing clothes, such as wearing some loose clothes, so that you won't look so fat.

If you look fatter than people of the same height and weight because of muscle relaxation, then I suggest that you can tighten your muscles through some exercise, so that your figure will look much better. You can learn to dance or do yoga, so you won't develop a sense of muscle. I have an aunt who is learning to dance now. After studying for a month or two, her figure has really improved a lot and her weight has not dropped. Or practice that kind of high-temperature yoga to lose weight.
