Fabio, National Academy Of Medicine Maximum, National Academy Of Medicine discussed on The Nutrition Diva's Quick and Dirty Tips for Eating Well and Feeling Fabulous


Diva podcast. I'm your host Monica. Ryan Eagle and today's show was suggested by Fabio. Who writes? I came across a study on bodybuilders, which suggests that a caloric surfeit doesn't contribute to weight gain as you would expect when the extra calories come solely from protein. Can you comment on it? The study Fabio asked me about was published in two thousand and fourteen in the Journal of the International. Society of Sports Nutrition and it is definitely worth a closer look. The subjects in this study were all in their early twenties, and they were all engaged in heavy resistance, training or weightlifting. They were quite lean and very muscular, going into the study in fact, if you looked only at their body, mass index their BMI numbers. It looked as if the subjects were on the verge of. City, but when you look at their body composition, it's clear that the higher body weights related to their heights word due to their very high muscle mass. One group in the study then added a lot of extra protein to their diet in the form of way, protein powder, and when I say a lot I mean a lot. These athletes had previously been consuming about one gram of protein per pound her day, or about twenty to twenty five percent of their calories. Now this is about twice the recommended minimum intake, but it's still comfortably within the acceptable range for protein that's laid out by the National Academy of Medicine, which is formerly known as the Institute of Medicine. For the study, the researchers essentially doubled the appleans protein intake to an average of three hundred grams per day now that is quite a bit higher than the National Academy of Medicine Maximum recommended intake, and it's also as the researchers point out, and I'm quoting here. The highest recorded intake of dietary protein in the scientific literature that we are aware of and quote. The researchers didn't evaluate whether this extremely high protein intake had any negative impacts on liver or kidney function, but many of the subjects did complain of intestinal distress during the study. However, nobody is recommending that eating this much protein would be a good idea on a long-term basis. The point of this short term study was simply to find out how eating protein in excess of caloric requirements would affect body composition in highly trained people, and when they say highly trained, they mean resistance training not trained in the scientific method or whatever. So? The subject's didn't eat less of other foods. They just added the way protein and of what they were already eating, or at least that's what they were supposed to do. In reality, some of the subjects ended up eating fewer carbohydrates. Others actually ate a bit more carbohydrate, but on average they managed to increase the caloric intake by eight hundred calories per day mostly from protein, and they also continue. Continue to do their usual strenuous workouts. So what were the results of this grand experiment? Well, according to the researchers and I'm going to quote again here. The current investigation found no changes in body, weight, fat, mass, or fat, free mass in the high protein Diet Group and this occurred in spite of the fact that they consumed over eight hundred calories more per day for eight weeks and quote. Now how is this even possible? Where did all of those extra calories go?.
