What physical changes did you notice in your body when walking more than 10k steps consistently?

Been walking anywhere from 10k-20k for 2 weeks. I haven't changed my diet. I haven't lost any weight but the front of my thighs have slimmed. I love walking because I don't feel super hungry after so it's a win win.

Have you seen physical changes from walking more than 10k consistently? What did you see and how long did it take to see it?
