“Keto is hard on the kidneys...Low carb is better.”

I think (subject to correction by others) what is tough on the kidneys is high-protein, which should be kept below 30% on all diets, ideally at 20% of all calories. The foods where that really shows up is in poultry (at around 60%) and fish (probably the same, but I haven’t run the numbers). Red meat (non-lean) and cheese get closer to 30% protein, while nuts and vegetables can get much lower in protein. So you do have to pay attention in that area.

But your advice is still very good, even for diabetics, as they may not get off insulin, but they should be able to cut down quite a bit on dosage.

When I started, I was pretty much “Dirty Keto” but over time I’ve cleaned it up. That’s probably the best way to ease into doing Keto.
The best thing is to eliminate processed foods, that’s the big win right there.

Ketone bodies are produced as your body burns fat. This is what can trigger metabolic acidosis, which is a known cause of chronic kidney disease. High protein diets can also be hard on the kidneys, which is just another one of many reasons why fad diets should be avoided. Of course, there are foods that can be high in both protein and fat.

The types of food you eat doesn't matter all that much because the best method for losing weight is to burn more calories than you consume. Same as it ever was. Consume more energy than you burn and you'll gain weight. The First Law of Thermodynamics has not been repealed.
