Below is a video demonstrating the 12000 plus calorie diet for Brian Shaw. Brian is the winner of the 2011, 2013, 2015 and 2016 World’s Strongest Man competition. In the video Shaw eats 7 meals during a single day and consumes a wide range of proteins, carbs and fats. He is 6’8 and weighs 423 lb.
I find it a struggle to fit in around 4500 calories.
