Do animals that are supposed to have a lot of fat on them suffer from any fat related problems like humans?

Animals like walruses and whales, just to name two, are supposed to have a lot of fat on them for survival. But do they suffer from any problems associated with humans and obesity such as clogged arteries, high cholesterol (that is negative), or diabetes? I know animals like dogs can suffer from these same things if they are overweight.

Bonus question: If they don't suffer from these sorts of problems, why is that?

Well, to answer this, you have to understand a little about the cause of problems from fat. Fat, in moderation, is actually beneficial to the body because it can both be stored for energy, and used for cushioning. For cushioning, fat cells are present around many of the vitals organs to protect them from concussive damage. However, as people become obese, their fat cells become larger to the point that they obstruct certain organs from operating properly, the most common being the lungs and heart. However, if a animal is supposed to be fat, their fat storage will be different to where it doesn't negatively impact their organs' ability to function.

As with arteries, cholesterol, diabetes, etc, it's not the being fat, per se, that causes these. You can be overweight/obese and not have any of these symptoms. However, diets that promote obesity also tend to cause these other diseases.

TL;DR "Fat" animals bodies are intended to be fat, and so do not necessarily have all the same negative effects of humans being fat.
