Here's why:
* We don't track gorilla weights like we do with humans. There's no official global record for heaviest gorilla.
* Gorilla weight varies significantly. Factors like age, sex, diet, and species all influence a gorilla's weight.
* "Fat" is a subjective term. It's not a medical term for gorillas, and it's difficult to determine if a gorilla is overweight without thorough veterinary assessment.
Instead of focusing on weight, we should be concerned with the health and well-being of all gorillas.
