Can confirm this is legit. I may only be 6'0" 140 lbs but when I got down to 132 lbs (high stress in college, not enough time to eat) my face looked godly and my ramus became very pronounced. I felt cranky, tired, and irritable though due to lack of calories. I'd rather sacrifice a little bit of facial aesthetics to eat what I want. I just have to be careful because if I get up to 150 lbs I lose jawline definition and my face starts looking bloated. I have low lean muscle mass so 150 lbs is actually skinny fat territory for me.
