I have a friend who is on kidney dialysis, and his protein intake is limited because protein builds up so quickly in his bloodstream. His dieticians tell him that even healthy people who eat too much protein will damage their kidneys trying to remove the wastes that it produces.
When all is said and done, people need to eat an all-around healthy diet. If they'd do so, they'd lose weight and feel better. If they don't, they'll be heavy. The diet doesn't need to be particularly low carb or high carb. It just needs to be balanced.

True. But what the food-nannies call a "balanced" diet has changed over the last 30 years from modest-carb modest-fat to low-fat and high-carb.
