As far as I know, Tom Brady follows a plant-based diet for almost always. This means he has not always been a vegan. I remember reading reports that said he consumed meat. It is easy to confuse a plant-based diet with veganism. The concept of veganism is beyond just eating plant-based food items. It is also about one’s lifestyle. Has Brady used any animal-based product? He has. Besides, I am not sure that the clothing and accessories that sportspeople like him use are all vegan.
 
This is why I do not buy into the theory that any A-list sportsperson is a vegan. How could they be one, if some endorsement involves the use of an animal-related product? I am not a vegan, but I do not believe in notions such as part veganism and half veganism. If you are a vegan, your diet and lifestyle are fully in line with veganism. Otherwise, you are no vegan.
