I liked the video format for sure. I disagree with the protein requirements, unless you are talking about sedentary individuals or possibly extreme endurance athletes. 56g of protein for a power or strength athlete would not be nearly enough. Look at vegans like David Carter who had to eat nearly 300g of protein per day while competing in the NFL. Or smaller guys like John Venus who are vegan physique guys. They recommend the more standard protein requirements for bodybuilders. In order to keep a positive nitrogen balance and muscle protein synthesis going, I've seen recommendations of about .8g-1g per pound of lean body mass. So you don't count fat weight, but you do need to keep your muscles fueled so they can continue to grow when stressed.
I went vegan about 6 weeks ago now. A few weeks prior to that I ran a vegan diet for week, but my lifts were regressing. Basically I was not recovering for my next workouts when I was eating around 170g of protein per day. After doing more research and looking at other vegan strength athletes, many recommended the amount I listed above. For me that is about 270g of protein per day. Now the second time around I am sticking with macros more like 270g protein, 730-750g carbs, and 75-80g of fat, and I feel much better. I am recovering for my workouts and making progress again.
