You are correct. The whole “beware of protein” narrative is completely wrong-headed. People here would likely be astounded by how much protein strength athletes eat with nothing but positive health effects.
High protein, low fat, low carb, low protein, high carb, high fat- collectively we've tried them all through one fad or another.
Currently IMO we're in a blowback period where we are seeing high carb is not panning out and many people are still afraid of fat, so protein is the next savior in line.
For what exactly? It pans out just fine for various things, or are you specifically talking about weight loss?
