Did Brian ever question his high protein intake? Is he possibly wrong?
Popular "Youtube Health/Lifestyle Doctors" such as Peter Attia, David Huberman, Dr. Layne Norton all seem to agree on a relatively high protein consumption of around 1 g/lb of bodyweight as a guide for optimal health. And they all bring the argument that more protein increases muscle mass and even if you overdo it, there is no harm.
Brian seems to ride this wave as well and follows a relatively high protein diet. He even consumes plant protein powder which is void of nutrition and fibre while arguing that every calorie has to fight for its life in his diet (hmm...). So I really am interested on which scientific base Brian aims for such high protein amount. At the end the goal is longevity, not muscle hypertrophy.
I was listening to an interview on the Viva Longevity Channel and it talks about the harms of high protein diets. But it's not what you think. It has to do with protein replacing healthy plants and fibre that we would have eaten if we didn't try to aim for large protein amounts. And while total protein intake isn't strongly linked to lifespan, higher intake of plant-based foods is associated with lower risks of chronic disease and longer life due to its high fiber and low saturated fat content.
Another issue is many people are moving away from real food to refined processed foods like protein bars or powders containing questionable ingredients to reach their protein target which then do harm the body. The Youtube video talks about a trending protein obsession.
Here is an interesting article if you like a quick read. Also researchist Gardner debunks the myth that plant protein is incomplete in this study from 2019.
