It completely depends on your lean weight, but 200g of protein is very high for most people who aren't athletes. I'm not in a state to work out whether the normal chorus saying that much protein will damage your kidneys is true or if I've just heard it enough times that it sounds true. Here's a publication that looks informative, but I haven't worked all the way through it and it may or may not support my presumption that 200 g of protein a day is too much for a male of average height who is not in an intense exercise regimen.

Not to defend (or bash) the proposed extreme diet but as far as we know your kidneys will be fine handling pretty much any amount of protein you can consume unless you have kidney disease. Most of it will end up being converted to glucose via gluconeogenesis. Said diet is certainly better for you than 30 years of fast food, as evidenced by the complete lack of protein-caused-disease in medical case studies opposed to... the obesity epidemic?

Don't worry about hypothetical lions around the bend when you're sprinting away from an angry tiger.

Definitely agree. If it helps control your appetite, it's not worse than continuing to carry all that weight. I just thought I'd throw that paper up because it seemed like a different take than I usually see. And just to stick my nose in and mention that 200 g a day is more protein than the vast majority of people need.

My gut would have something to say about all that protein before my kidneys even noticed, honestly.

I am not a physician. You don't need to worry about protein intake damaging kidneys unless you have preexisting kidney problems.
