Animal protein is more bioavailable and is higher in branch chain amino acids (BCAAs) than plant protein. Therefore, if you’re a vegan and aren’t consuming any animal products, you’ll need more protein overall to have the same impact on muscle growth and preservation. Gram for gram, plant-based proteins are less efficient at turning on muscle building pathways than animal proteins, so the Avatar system is designed to compensate and keep you at the best protein level to hit your goals.
In addition to setting proper protein levels, selecting a vegan status in the app will filter suggested foods and recipes to only show options that fit your diet restrictions.
