Cornelia C. Metges, Christian A. Usually relatively short-term experimental studies on the effects of high-protein intakes have been performed, and so the consequences of longer-term or chronic nutrient intake are difficult to judge. Epidemiologic evidence, on the other hand, which aims to circumvent this difficulty, can be flawed by various biases, confounding effects or even limitations of the data which make it difficult to obtain clear-cut cause-effect relationships Taubes Moreover, no extensive body of data exists covering the issue. However, there are bits and pieces of information suggesting that there is no benefit from increasing the dietary-protein intake far above the recommended intake level. Below we summarize the relevant available literature and attempt, by making prudent assumptions, to estimate a TUL which is defined as the highest level of daily intake that is likely to pose no risk of adverse health effects Institute of Medicine, Food and Nutrition Board One of the main questions is whether chronic intake of high-protein diets may be of any value in promoting increased lean body mass Garlick et al. The answer to this question is important not only for athletes and body builders who tend to believe that a high-protein intake is crucial for their physical performance Linseisen et al.

Other workers disagreed with the concept of a diet lethal catabolism calorje, and, as should become apparent later catabolism this low, both the extent of weight loss and survival time protein on the initial degree of adiposity see Table 2 for some remarkable cause records of weight loss in fasting obese subjects.

Dietary proteins have been used for years to treat obesity. Body weight loss is beneficial when it concerns fat mass, but loss of fat free mass — especially muscle might be detrimental. This occurs because protein breakdown predominates over synthesis, thus administering anabolic dietary compounds like proteins might counter fat free mass loss while allowing for fat mass loss. Indeed, varying the quantity of proteins will decrease muscle anabolic response and increase hyperphagia in rodents fed a low protein diet; but it will favor lean mass maintenance and promote satiety, in certain age groups of humans fed a high protein diet. Beyond protein quantity, protein source is an important metabolic regulator: whey protein and plant based diets exercize favorable effects on the risk of developing obesity, body composition, metabolic parameters or fat free mass preservation of obese patients. Specific amino-acids like branched chain amino acids BCAA, methionine, tryptophan and its metabolites, and glutamate can also positively influence parameters and complications of obesity especially in rodent models, with less studies translating this in humans. Tuning the quality and quantity of proteins or even specific amino-acids can thus be seen as a potential therapeutic intervention on the body composition, metabolic syndrome parameters and appetite regulation of obese patients. Since these effects vary across age groups and much of the data comes from murine models, long-term prospective studies modulating proteins and amino acids in the human diet are needed. Obesity has become a major public health problem because of its high prevalence in both developed and developing countries and its major complications, such as diabetes mellitus, cardiovascular diseases, respiratory failure and cancers.
