Many college students have been going to gym and workout throughout school year. And most of them know that to get a fitter body, “low-carbs, and high-proteins” diet should be incorporated with their workout. It is obvious for the body builders to know that carbohydrates will breakdown into smaller sugar forms. So they would prefer diets with lower-carbs in general. It helps them to reduce the amount of sugar transforming into fat. And yes, it makes perfect sense that taking in plenty of protein allows body to rebuild stronger muscles faster after workout. Yet, for long-term speaking, should we consume as much protein as possible the better?
According to Francine Segan, a food historian, many ancient writers wrote that Olympic athletes would avoid grains and breads for half a year. She also said there are many fragments of other documents suggest that athletes consumed diets rich in protein and fibers—also as known as Mediterranean diet. Even ancient athletes believed in high protein and low carbohydrates diets help to build stronger, more enduring muscles. The fact that high lean protein diets help us build muscles with better performance is supported by many scientific researches.
Another research group led by Stephen Simpson andDavid Le Couteur at the University of Sydney conducted an experiment which assigning different diets to mice and compare their average lifespan. For the result, the low-protein/high-carbohydrate diet appears to extend lifespan. The study shows that animals with this diet had lower blood pressure, better glucose tolerance, and healthier cholesterol. Those mice consumed lots of protein were skinner but lived shorter than the otherwise. But how come fatter animals are healthier? There are findings state that reducing protein intake can lower the level of IGF-1 growth factor, which with higher level has a greater risk of cancer and diabetes. Low level of protein can also lower the level of mTOR, which with a lower level can extend the lifespan of mice.
These studies suggest that high level of protein is able to create the leanest muscles with better performance. However, it could also shorten the lifespan of animals. If high level of protein consumption will lead to shorter lifespan, is most of the body builders and athletes achieving health and longevity or the otherwise?
