Yes and no. According to the research I'm familiar with (unfortunately, so far with animals, not people), your liver begins kicking into gluconeogenesis somewhere between .5 and .7g of protein per pound of lean body weight, and converts it to glucose at a ratio of between .67 (high carb) and .75 (low-carb). It's a lossy process, though, with only around a .6 conversion ratio.
So let's play a math game for a second. You don't need it to lose weight, but it's fun to play with numbers. Let's assume you have 150 lbs of lean weight, you're low-carbing, and we're taking the high number from current estimates:
* Protein used whole by the body: .7g * 150lbs = 105g/lb . Protein remaining: 95g
* Protein converted to glucose: .75 * 95g = 71g converted at ratio of .6 efficiency = 43g glucose equivalent
* Additional protein used whole by the body: 200g - 95g -71g = 34g
Now, these are my current estimates based on my understanding of the research; it could be wrong. But basically, if you over-consume protein, you can be certain that some amount is going to be converted to glucose, driving up insulin and working against your goals. On the other hand, the best way to ensure muscle growth is to keep a steady supply of protein in your bloodstream after your muscles have enjoyed a hypertrophic workout within the last few days.
It's an interesting balancing act that may very well vary by person. Best of luck!
Note: The allegation that a high-protein diet causes any kidney issues for people with healthy kidneys is entirely unfounded and without any scientific merit. High blood urea is a symptom of kidney failure, not a cause. Additionally, the single greatest cause of kidney failure is
diabetes, for which a moderate-protein, high-fat diet is the best treatment.
Ignore the "high protein kidney stress" arguments; they are totally specious and have been repeatedly disproved for people with healthy kidneys. Unless you are already in (probably diabetes-induced) kidney failure, your blood protein levels are irrelevant to kidney function.
