>I started doing Karate and my weight went down quick and I notice my face gets leaner and now I have a defined jaw line. I’m not sure maybe just my genetics but maybe you got your jawline from losing weight. I was skinny and atheletic type with super low body fat then I didn't have visible square jaw. After that I started eating lot more and training hard, so I did gain some muscle (early newbie gains) but gained fat also. So now my muscles while I could feel them, got burried under layer of fat. People in my tribe don't have strong jaw. It's hard to find them even in the village I hail from, you can find strong built bulky men and women but no strong jaws.
