CrossFit Games GOAT, Mat Fraser, had physiological testing done that would show his 5'7", 190lb, frame needed 8000 to 9000 cals to support his two 2 to 2.5-hr intense training sessions per day. He's talked about 500 cals in super-concentrated high-cal juice/sports drinks immediately after each session as being essential for muscular recovery and calorie accumulation. Modern-day wrestlers are doing these same recovery carb cals after weigh-ins and between matches. If Keuter is doing it after lifting and after practice each day, he's down to 5k needed for meals, protein shakes, and snacks.
