Some Experts Worry About Long-Term Impacts Of High-Protein Diets.

reports that “while some nutritionists have encouraged the protein craze, a number of experts are urging caution.” The Times says that “they point out that protein powders and supplements...are a relatively new invention” and that “there are no rigorous long-term studies to tell us how much protein is too much.” The Times adds that “short-term studies suggest that high protein, low carbohydrate diets may promote weight loss and help to preserve lean muscle, and that eating protein helps satisfy hunger.” But, according to the Times, “a recent small trial found that older women who lost weight on a high protein diet did not experience one of the important benefits that usually follow weight loss, an improvement in insulin sensitivity, which reduces the risk of developing Type 2 diabetes.” Meanwhile, “large population studies also suggest an association between habitual high protein intake and a heightened risk of diabetes.” http://www.nytimes.com/2016/12/06/well/eat/can-you-get-too-much-protein.html
