Je me pose la question car mon ratio tourne à un peu plus de 200g pour 75kg depuis 1 an, je n'ai aucun problème de santé mais j'aimerai savoir si mon corps réagirait aussi bien en consommant moin de proteines.
Je laisse la parole aux pros

staz26 a écrit:on conseille en général 1.5g à 2g voir 2.5g de proteine par kilo de poid corps. Mais si la personne doit consommer 150 g de protéine par jour et qu'elle en prend 200, les 50g de protéines en plus sont quand même bénéfique pour les muscles ou c'est 50g inutiles qui partiront dans l'urine?
The present study examined the effects of training status (endurance exercise or body building) on nitrogen balance, body composition, and urea excretion during periods of habitual and altered protein intakes. Experiments were performed on six elite bodybuilders, six elite endurance athletes, and six sedentary controls during a 10-day period of normal protein intake followed by a 10-day period of altered protein intake. The nitrogen balance data revealed that bodybuilders required 1.12 times and endurance athletes required 1.67 times more daily protein than sedentary controls. Lean body mass (density) was maintained in bodybuilders consuming 1.05 g protein.kg-1.day-1. Endurance athletes excreted more total daily urea than either bodybuilders or controls. We conclude that bodybuilders during habitual training require a daily protein intake only slightly greater than that for sedentary individuals in the maintenance of lean body mass and that endurance athletes require daily protein intakes greater than either bodybuilders or sedentary individuals to meet the needs of protein catabolism during exercise.

Determining macronutrient intake
Protein
Adequate protein consumption during contest preparation is required to support maintenance of LBM. Athletes require higher protein intakes to support increased activity and strength athletes benefit from higher intakes to support growth of LBM [5,22-28]. Some researchers suggest these requirements increase further when athletes undergo energy restriction [13,16,22,28-33]. Furthermore, there is evidence that protein requirements are higher for leaner individuals in comparison to those with higher body fat percentages [7,33,34].
The collective agreement among reviewers is that a protein intake of 1.2-2.2 g/kg is sufficient to allow adaptation to training for athletes whom are at or above their energy needs [23-28,35-38]. However, bodybuilders during their contest preparation period typically perform resistance and cardiovascular training, restrict calories and achieve very lean conditions [2-6,17-21]. Each of these factors increases protein requirements and when compounded may further increase protein needs [33]. Therefore, optimal protein intakes for bodybuilders during contest preparation may be significantly higher than existing recommendations.
In support of this notion, Butterfield et al. [22] found that male athletes running five to 10 miles per day during a slight caloric deficit were in a significant negative nitrogen balance despite consuming 2 g/kg of protein daily. Celejowa et al. [39] showed that five out of 10 competitive weight lifters achieved a negative nitrogen balance over the course of a training camp while consuming an average protein intake of 2 g/kg. Out of these five, as many as three were in a caloric deficit. The authors concluded that a protein intake of 2–2.2 g/kg under these conditions only allows for a small margin of error before nitrogen losses occur.
Walberg et al. [32] examined the effects of two energy restricted isocaloric diets of differing protein intakes in 19 lean (9.1-16.7% body fat), male, non-competitive body builders. One group consumed a protein intake of 0.8 g/kg and higher carbohydrates, while the other consumed 1.6 g/kg of protein with lower carbohydrates. The length of the intervention was only one week, but nonetheless nitrogen losses occurred only in the lower protein group and LBM decreased by a mean of 2.7 kg in the 0.8 g/kg protein group and by a mean of 1.4 kg in the 1.6 g/kg protein group. While the high protein group mitigated LBM losses compared to the low protein group, they were not eliminated.
A recent study by Mettler et al. [29] employed the same basic methodology as Walberg et al. [32]. However, one group consumed a protein intake of 1 g/kg, while the other consumed 2.3 g/kg. The high-protein group lost significantly less LBM (0.3 kg) over the course of the two week intervention compared to the low-protein group (1.6 kg). Unlike Walberg et al. [32] calorie balance between diets was maintained by reducing dietary fat as opposed to carbohydrate to allow for the increase in protein.
While it appears that the 2.3 g/kg protein intervention in Mettler et al. [29] was superior for maintaining LBM compared to 1.6 g/kg in Walberg et al. [32] a recent study by Pasiakos et al. [40] found a trend towards the opposite. In this study, a non-significant trend of greater LBM retention occurred when subjects consumed 1.6 g/kg of protein compared to 2.4 g/kg of protein. However, the participants were intentionally prescribed low volume, low intensity resistance training "to minimize the potential of an unaccustomed, anabolic stimulus influencing study outcome measures". Thus, the non-anabolic nature of the training may not have increased the participants’ protein requirements to the same degree as the participants in Mettler et al. [29] or to what would be expected among competitive bodybuilders.
Maestu et al. [6] did not observe a significant loss of LBM in a group of drug free bodybuilders consuming 2.5-2.6 g/kg of protein during the 11 weeks prior to competition. These results when considered alongside the works by Walberg et al. [32] and Mettler et al. [29] imply that the higher the protein intake, the lower the chance for LBM loss. However, it should be noted that this study did not include a low protein control and not all studies show a linear increase in LBM preservation with increases in protein [40]. Furthermore, two subjects did lose significant amounts of LBM (1.5 kg and 1.8 kg), and the authors noted that these specific bodybuilders were among the leanest of the subjects. These two subjects lost the majority of their LBM (approximately 1 kg) during the latter half of the intervention as their percentage of calories from protein increased from 28% to 32-33% by the end of the study. The group as a whole progressively decreased their calories by reducing all three macronutrients throughout the investigation. Thus, the two subjects uniquely increased their proportion of protein, possibly reducing fat and carbohydrate to the point of detriment [6]. That said it is also plausible that the lost LBM seen by these two subjects was necessary in order to achieve their low levels of body fat. It is unknown whether or not the lost LBM influenced their competitive outcome and it is possible that had the competitors not been as lean, they may have retained more LBM but also not have placed as well.
In a review by Phillips and Van Loon [28], it is suggested that a protein intake of 1.8-2.7 g/kg for athletes training in hypocaloric conditions may be optimal. While this is one of the only recommendations existing that targets athletes during caloric restriction, this recommendation is not given with consideration to bodybuilders performing concurrent endurance and resistance training at very low levels of body fat. However, the recently published systematic review by Helms et al. [33] on protein intakes in resistance-trained, lean athletes during caloric restriction suggests a range of 2.3-3.1 g/kg of LBM, which may be more appropriate for bodybuilding. Moreover, the authors suggest that the lower the body fat of the individual, the greater the imposed caloric deficit and when the primary goal is to retain LBM, the higher the protein intake (within the range of 2.3-3.1 g/kg of LBM) should be.

On peut observer exactement la même chose avec un régime très riche en glucide, surtout en choisissant les bonnes sources de glucides, très riches en fibres.*
De même, il a été démontré que la consommation de viandes induit une prise plus important de poids tout en contrôlant pour la quantité de kcal consommer.
Les régimes hyper-protéinés, essentiellement a base de protéines animales, sont a déconseiller pour la santé rénales. De plus ces régimes seront suivies pour des périodes très longues par des bodybuildeurs (plusieurs années).
* je suis personnellement un régime "high carbs" (75% glucides, 15% protéines et 10% graisses) et j'ai perdu ainsi plusieurs kg tout en conservant ma masse musculaire (prise de force même!). Je suis a environ 10% de matière grasse a l'année sans efforts. Et sans reprendre de poids!

Overall, the prevalence rate of CKD increased from 10.0% (95% CI, 9.1-10.9) to 13.1% (95% CI, 12.0-14.1).
The Nurses' Health Study reported an association of animal protein intake with renal function decline in women already presenting with mild kidney function impairment but not in women with normal kidney function (85). Renal function decline was observed with animal protein-rich diets but not with plant protein-rich diets, emphasizing the importance of the source of protein (and fat) rather than the amount regarding adverse health consequences.
Source: http://www.ncbi.nlm.nih.gov/pubmed/17976426The rate of clinical diagnosis among those with chronic kidney disease was 26.5% (95% confidence interval, 17.9 to 35.1), suggesting that 74% of patients with chronic kidney disease are undiagnosed.

Tu ne crois pas que le problème vient plutôt des graisses saturées (moindre), produits laitiers et sucres plutôt que les protéines animales? Quid de la diète paléo qui donne tout de même de bon résultats sur la santé?
Et pour les résultats de l'étude sur les oeufs, là je me base aussi sur mon expérience. Je consomme en moyenne 3 oeufs par jour et à ma dernière prise de sang (<1 mois) mes taux des cholestérol étaient très bon.ça fait 3 ans pour moi que je participe à un protocole à la salpetrière avec une mesure de cholestérol tous les six mois ,je mange 3 oeufs / jour et mon ratio cholestérol est passé de 2,04 à 1,14 en un an (stable pour le moment) j ai juste limité les graisses saturées ,les produits laitiers ( beurre, yaourts,fromage, viandes grasses, les sucres ajoutés )
On ne peut pas pointer du doigt qu'un seul aliment ou source alimentaire...

Seulement premier sur lequel je tombe c'est une étude sur la "western style diet". Donc aucun rapport avec le sujet...
Mais au lieu de juste lire des études. Qui dans 90% des cas sont mal faite.
Faut surtout utiliser son bon sens et avoir des connaissances en physio et diététique.
Euh...western style diet...qu'est ce que vous ne comprenez pas. Le régime western style diet est classiquement riche en protéines d'origines animales, en graisses saturés, en produit laitiers et en sucres. Il y a des similarités remarquables avec de nombreuses diètes que l'on peut rencontrer chez des bodybuilders et même sur ce forum et le site web associé a ce forum.
Donc il y a un très réel rapport avec le sujet.
Je suis d'ailleurs persuadé que vous n'avez pas lu les études que j'ai posté.
Mais bon, je vais arrêter d'essayer de vous persuader. Vous ne semblez pas vouloir accepter des études scientifiques comme arguments. D'ailleurs, je vous demande d'ou viennes vos "connaissances en physiologie" ? Est-ce que vous pensez que ces connaissances ne sont pas le résultat d'études scientifiques ? Ne serait il pas contradictoire de prétendre que 90% des études sont mal faites alors que en même temps vos connaissances en physiologie sont le résultat direct d'études scientifiques? Vos connaissances sont elles valides si ceci est le cas ? De plus, quel est exactement l'étendu de vos connaissances dans ce domaine ? Et si vous avez ces connaissances, comment se fait il que vous êtes incapable de réfuter mes affirmations ?

Est-ce que votre prise de sang a été lorsque vos étiez a jeune ? Pouvez-vous poster vos valeurs?
Il faut aussi comprendre que pas tout les individus réagissent de la même façon a ce type de diète. Certains auront un taux de cholestérol beaucoup plus élevés que d'autres en suivant exactement la même diète.
Je déconseille le régime paléo qui supprime la consommation de fruit sucrés, de graines, d'amidon et de légumineuses.
