Dr. Herta Spencer, of the Veterans Administration Hospital in Hines, Illinois, explains that the animal and human studies that correlated calcium loss with high
protein diets used isolated, fractionated amino acids from milk or eggs.19 Her studies show that when
protein is given as meat, subjects do not show any increase in calcium excreted, or any significant change in serum calcium, even over a long period.20 Other investigators found that a high -
protein intake increased calcium absorption when
dietary calcium was
adequate or high, but not when calcium
intake was a low 500 mg per day.21
First, multiple 24 - h
dietary recalls reduce measurement error, and 15
dietary recalls are considered more than
adequate to capture a person's usual
intake of carbohydrate,
protein, fat, and fiber (33).
The ketogenic diet is simply one that restricts carbohydrates, especially refined carbohydrates, allows moderate or
adequate protein intake, and enhances healthy organic
dietary fat consumption.
Mettler, et al. [29] also found that a caloric reduction coming from
dietary fat while maintaining
adequate carbohydrate
intake and increasing
protein to 2.3 g / kg maintained performance and almost completely eliminated LBM losses in resistance trained subjects.
I would suggest that for humans to have developed the ability to stay in ketosis even with more than sufficient
protein intake, we must have at least have spent frequent long periods in a condition of very low carbohydrate, high fat access, either exogenously or endogenously, and more than
adequate protein as a
dietary norm.
The overall calcium balance appears to be unchanged by high
dietary protein intake in healthy individuals (13), and current evidence suggests that increased
protein intakes in those with
adequate supplies of
protein, calcium, and vitamin D do not adversely affect BMD or fracture risk (14).
