Yeah, he does look a little worse like he lost too much weight. I don't think an active man can stay at 170lbs eating only 1500 calories even with a slow metabolism.He is looking worse in that recent interview compared to other videos, it might be because he added in sourdough bread to his diet recently (and that might have some bad in it like iron or glyphosate) or he is just going through a period where he is looking worse
I was going to say it could be camera angles and filters etc but I see what you're saying. He looks drained compared to months back.
