A major scientific review is challenging the idea that more protein is always better.

The review, led by pathologist and biomedical researcher Dudley Lamming and published in the journal Cell Press Blue, examined more than 350 studies involving humans, mice, insects, yeast, and other organisms.

The review found that eating less protein, or less of certain amino acids that make up protein, may turn on body processes linked to healthier aging, as well as metabolism, the process by which the body turns food and drinks into energy.

I'm going to guess it's overeating in general. Protein as a proxy for calories. Undereating does extend life, that gets proven over and over. And yeah, too much protein is hard on your kidneys.

But I would bet money that a person is better off being more active, so that they burn off the calories they eat, or fasting sometimes and eating less overall.

Just holding calories steady and reducing protein doesn't seem better. Because the other places calories can come from are carbohydrates and fats, and it's not healthy to eat too much of those either. Therefore I think it probably just means don't overeat or even do undereat.
