It has always been my understanding that older people needed diets more protein-rich and younger people tolerated carbohydrates better. There are many people who have lost weight by doing a keto-style diet where they ignore carbs and just eat meats. Contrary to many critics, these diets work and help people lose weight and they appear to be healthier. A recent blog post I found disputes the idea that we need so much protein. While its true that we know a lot of things about the body, its also true that many things that scientists do not understand about nutrition as well as you may think.

The irony is that while the body makes hundreds of amino acids in the course of a day, it’s unable to make nine of the so-called essential amino acids. We get those amino acids from foods, and they have big jobs.

It actually isn’t all that complicated, although the rules, so to speak, change if you’re an athlete or someone who spends hours at the gym. Read more
