The discovery, reported in the American Journal of Clinical Nutrition, suggests that the widespread practice of throwing away egg yolks to maximize one's

To examine the relationship between
dietary intake of major sources of
protein and kidney function, a team led by Woon - Puay Koh, MBBS (Hons), PhD (Duke - NUS Medical School and Saw Swee Hock School of Public Health in National University of Singapore) analyzed data

For example, in a study published in The American Journal of Clinical Nutrition, Weigle et al. showed that an increase in
dietary protein from 15 % to 30 % of energy and a reduction in fat
from 35 % to 20 % produces a sustained decrease in appetite and calorie
intake and results in significant weight loss, and other researchers have gotten similar results when comparing
protein and carbs in terms of satiety.
«the lowest level of
dietary protein intake that will balance the losses of nitrogen
from the body, and thus maintain the body
protein mass, in persons at energy balance with modest levels of physical activity.»
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
Basically we want about 10 - 20 % of our

In conclusion, a 15 % increase in energy

intake produces a sustained decrease in ad libitum caloric
intake that may be mediated by increased CNS leptin sensitivity and results in clinically significant weight loss.
Conclusions: An increase in
dietary protein from 15 % to 30 % of energy at a constant carbohydrate

A high
protein diet, where studies show the most benefit, is considered one where anywhere
from 20 - 35 % of calories are coming
from protein, and yet most people who come to see us at Parsley are averaging less than 15 % of
dietary intake from protein.
A classical ketogenic diet — with a staggering 70 - 90 percent of total calories coming
from fat — might not be necessary.51 Classical ketogenic diets restrict
protein as well as carbohydrate, since 48 - 58 percent of the amino acids in
dietary proteins can be glucogenic, thereby undermining the purpose of a diet intended to generate a high amount of ketones and limit glucose as much as possible.46 As therapy for AD, however, simply lowering carbohydrate
intake to a point where some ketones are generated and hyperinsulinemia is corrected could have positive effects just by easing the metabolic burden on the brain.
According to the Institute of Medicine, children ages 4 to 18 should obtain no more than 30 percent of their daily calorie
intake from dietary protein, which is a maximum of 120 grams of
protein per day for children consuming 1,600 calories a day.
Only those who markedly decrease their animal
protein intake may expect to benefit
from dietary recommendations.
In humans, data collected
from 38 different trials of food consumption that used widely varying
intakes of
protein,
from 8 to 54 % of energy, showed: «Percent
dietary protein was negatively associated with total energy
intake (F = 6.9, P < 0.0001) irrespective of whether carbohydrate (F = 0, P = 0.7) or fat (F = 0, P = 0.5) were the diluents of
protein.
A number of other
dietary factors can impair the production of anti-inflammatory hormones, thereby increasing the inflammatory ones: low levels of vitamins B6, C, E, niacin, and the minerals magnesium, calcium, and zinc (these should come
from a healthy diet); trans fat; low
protein intake; excess stress; and aging, which increases the risk of more inflammatory chemicals.
Ten to 35 percent of your caloric
intake needs to come
from protein, states the
Dietary Guidelines for Americans 2010.
A review of the somewhat limited data
from these and earlier studies (1) indicated that inhibition of tumor development as a result of marginal
intakes of various
proteins could be abolished by supplementation with the respective limiting amino acid for each
protein... [O] ur results suggest that the enhancement of focus development by lysine supplementation of gluten is due to a general improvement in
dietary protein quality and not to any particular metabolic effect peculiar to lysine.
Protein change theory states that for strength and muscle gains there must be a sufficient increase in dietary protein from habitual intake to study intake.1 This means once a study comparing protein intake establishes sufficient «spread», the researchers must also ensure that the subjects are consuming sufficiently more protein than their typical, pre study

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.
Subjects with renal insufficiency, even subclinical, kidney transplant patients and people with metabolic syndrome or other obesity - related conditions, will be more susceptible to the hypertensive effect of amino acids, especially of the sulphated variety.104 The well - documented correlation between obesity and reduced nephron quantity on raised blood pressure puts subjects with T2D or metabolic syndrome at risk, even if in diabetics with kidney damage the effects are not always consistent with the hypothesis.12, 105,106 In fact, although some authors have reported a positive influence of a reduction in
protein intake from 1.2 to 0.9 g / kg, over the short term, on albuminuria in T2D, 107 the same authors have subsequently stated instead that
dietary protein restriction is neither necessary nor useful over the long term.108
These «deficiencies» are usually
from suboptimal or outright deficient
intake of some important nutritive factors, and while
dietary protein or fatty acids deficiencies (which do impair testosterone production) are almost unheard of there are some vitamins or minerals which are a bit more commonly deficient.
After adjusting for major lifestyle and
dietary risk factors, the HR per 10 % increment of animal
