Bear Size ~

Let's say you are a native grassland, hunter-gatherer type of African. You have to do so much work to sustain yourself just to get the most basic necessity: food. However, we as humans naturally decline in muscular force production, regardless whether we do the same thing for 80 years. By age 80, you would only have about 50% of your muscle left, even though you're doing the same thing for since teen years, just at a less forceful pace. A person who lived for the first twenty years of his life eating junk and staying in the basement would quite literally be a "huge pile of fat" unlike a person living actively.

Not so the case with normally-active animals such as bears, cats, bovines, or large reptiles. Bears and cats in captivity, even given the fattest foods ever with minimal excercise, would still be (not sure about looks, though, for bears) quite muscular for their weight, yet just a tad fatter than if they were in the wild. The reason why they can still be extremely muscular even if given minimal exercise is because the genes are already set for them over millions of years as carnivores to actively hunt food. They wouldn't be total fat slobs compared to a wild version of themselves, unlike us. We simply regulate muscle and fat dufferently.

Taking post-prime years and muscle deterioration into account, its safe to say that Jimbo is not entirely fat, just slightly less muscular than Bart or Van. A basement-dwelling man at about 250 pounds, on the other hand, would have at least 40% more more body fat than a 230 pound, 20% bodyfat man who actively plays as a quarterback in football. Reply
