If it is not the cause of edema, your legs are different in thickness and must be accompanied by a waist injury.

As you said, there is fat in the front and back of the thigh, which can be shaped by exercise. But the thickness is different, but it is very troublesome.

You have to make sure that there is something wrong with your psoas muscle or lumbar spine. Adjust here first, then reduce your legs.

There is a lot of fat on the back, which means that you rarely stand, but most of you sit. Being fat before is caused by not going up stairs and exercising often.

Obesity is related to diet.

Please look for the root cause of different leg thickness first. This is very unhealthy, more serious than obesity.
