BUZZZZZ! Sorry, wrong question for a doctor to ask. Please thank him for playing "Let's Pretend I Know Something About Nutrition".
Seriously, I sure wouldn't take ANY form of dietary advice from someone who asks this question, I don't care whether he's a doctor or not. I could see a question like, "Are you supplementing B-12?" or something like that, but not THE protein question. I would have laughed at him. At this point you know more about nutrition than your doctor does.
Sorry, guess I ranted a little bit...
Vegetarianism, bone loss, fracture and vitamin D: a longitudinal study in Asian vegans and non-vegans. European Journal of Clinical Nutrition (2012) 66, 75–82
In spite of the fact that....
"The prevalence of vitamin D insufficiency in vegans was higher than in omnivores (73% versus 46%; P 1⁄4 0.0003)."
The study concluded...
"Conclusions: Vegan diet did not have adverse effect on bone loss and fracture. "
However...
"Corticosteroid use and high intakes of animal protein and animal lipid were negatively associated with bone loss."
From the study..
On Calcium
"We found no significant effects on dietary calcium and vitamin D on bone loss. Dietary calcium intake in the present study’s participants was relatively low, but it did not have adverse effect on bone loss. Indeed, the average dietary calcium intake among vegans was only 375mg/day, much lower than the intakes observed in non-vegetarians (683 mg/ day). In both groups, the dietary calcium intake was well below the recommended level of 1000 mg/day. Nevertheless, the low levels of dietary calcium did not have any adverse effect on either BMD or bone loss in both vegetarians and omnivores."
On Vitamin D
"Disturbingly, almost 3/4 vegans had 25(OH)D levels at the level of insufficiency and more than a quarter at the level of deficiency. Although these prevalence rates were significantly higher than non-vegetarians, the difference did not seem to translate into adverse effect on bone density or bone loss. Indeed, we found no significant correlation between 25(OH)D and BMD or changes in BMD. Although the null association could be attributed to sample size, measurement errors of both BMD and 25(OH)D, and the duration of follow-up, the finding suggests that vitamin D may have modest effect, if any, on the rate of bone loss in postmenopausal women."
NOTE: The vegans averaged at Vitamin D Level of 26.1, which by older standards was defined as insufficient. However, according to the new IOM Consensus Statement, a level of 20-30 is now considered sufficient and not insufficient and this study seems to prove that out. They were not insufficient, their levels were just lower that those on a more omnivorous diet but these higher levels in the omnivores was not protective of their high animal protein diet.
There is more to nutrition than isolated lab numbers and isolated nutrient intakes.

What we didn't see eye to eye on was the "diet" which I tried to explain was a lifestyle change. He understood that part of it, but he believes I will be "out of balance." I told him I gave up all meat, dairy and oils. He called it "extreme". He also said diet has helped you get to this point today, but what will you do in the future? He also asked me where was I going to get my protein from.
