Coworker: “I’m on a keto diet, I’ve been having 6 eggs for breakfast everyday”
Me: “Wow, that sounds taxing on your liver, maybe check your plan with a doctor nutritionist”
Coworker: “Yes, it was my gym nutritionist who designed the diet, I also do protein shakes”
He is a personal trainer, and specifically a trainer/coach for professional bodybuilders. This is broscience and simply not reasonable advice for normal people. Normal people (like you, like me, like basically everyone even if you exercise by weight training) need normal amounts of protein.
