I think his view point is part enthusiasm and part virtue signaling. I have maintained a steady body weight my whole life. I eat whatever I want at normal portion sizes. And watch sugar. I like a few chocolates, maybe an ice cream cone (two small scoops) at home with the kids. Not on a regular basis. No soda.  My favorite breakfast is raw eggs from my chickens in a shaker with whole milk and a splash of chocolate- a splash!! Keeps me full a long time. Plus, it’s fast and I’m in a hurry. I really like protein because it’s filling. No powders though. And frankly animal fat is filling too. But I can eat it because I don’t overeat or snack.  Those are things I do. I’m not fat at all and try to help others think beyond “dieting” This guy sounds like a diet martyr.
