Here's something to put Gort into perspective: his body-mass index (BMI) is 45.8 kg/m^2. McCaskill, according to El Jefe's data, had a BMI of 34.5. Anything over 30 is considered obese. So McCaskill was in the obese territory, but not so far out of the ordinary. Now, maybe half-orcs have a somewhat different body type than humans, so let's compare. According to the standard D&D height-weight tables, the average human male is 5'9.5", 175 lb for a BMI of 25.5; the average half-orc male is 5'11.5", 241 lb for a BMI of 33.1. Clearly half-orcs have somewhat higher BMI typically than humans, and are probably healthier with a high BMI than a comparable human. So maybe a BMI of 45 for a half-orc is comparable to mid-30s for a human. (The largest human that can be generated on the table has a BMI of only 32.4, and that is also the maximum possible for a human male.) In that case, Gort's weight doesn't seem that extreme, but I will cling to my earlier statement that he's probably not very healthy.
