Yeah I had an idea for a sub-race of elfs that is loosely inspired from Elf-san and contemporary portrayals of elfs, called "pork elfs", but they don't really have an official name.
Basically, they are anatomically similar "normal elfs" where they have slightly longer limbs than humans, longer lifespans, long pointy ears. But where they differ are a few key anatomical differences.
Obviously these elfs tend to be fatter on average, but that is due to a few changes related to their diet. Pork elfs are omnivores and are more than willing to eat meat, particularly pork hence their name, they also are not nomadic and have an elaborate agrarian and ranching society, crops that are calorie dense like potatoes, beets, and corn are very commonly grown. As such they very rarely have food shortages. However many pork elfs also suffer from a mental condition where their brains produce a bit too much hunger hormones, leading to higher than average body fat content even for this sub species although it is not extreme enough of a disorder to cause morbid obesity on it's own. Due to a lot of reasons mentioned later, pork elfs also have a much higher basic metabolic rate compared to elfs and even humans, as a typical sedentary BMR for a Pork Elf is close to 3000kCal, but can be as high as 10,000kCal in very large individuals living in subzero climates.
As for other anatomical differences; they tend to be slightly taller than normal elfs (assuming you are talking about elfs from a fantasy setting where they are slightly taller than humans), ranging around 6'6" to 8'0" in height.
They have far more developed muscle mass through out their whole body, but are not ripped; although with some training they could easily do so, at least easier than adult human male could with the same level of effort. The extra muscle mass is more pronounced in their legs causing them to just naturally have very well developed legs. Although this also allows them to move far more easily while being extremely obese, roughly twice as easily than a human at the same BMI.
They also have an affinity for slightly colder climate, due to being able to develop a layer of brown fat that can grow from 0.1 inches in cool climates to a whopping 1.5 inches in extremely cold climates that could be frozen year round, often shrugging off temperatures as low as -40F with little more than what would be modest winter clothing for a human. Although not to say they can't enjoy warmer climates, they just tend to not dress very heavily at all.
Naturally having longer legs and feet, combined with a having more fatty and muscle mass they tend to be elegant swimmers, while clumsy in the forest compared to a typical elf they are masters of the water and have a much easier time floating and can easily swim 50% faster than a human with roughly the same amount of physical exertion.
Largely due to their diet Pork Elfs tend to have a slightly larger brain mass and further development, allowing them on average to be slightly more intelligent than elfs and humans, although when they get tired their focus awareness takes a massive hit. Many Pork Elfs suffer from becoming "hangry" while being very hungry and they love to eat for a quick surge in happiness.
Obviously they are massively geared toward weight gain, but this is offset by them having a really high BMR, making it rather difficult for them to become extremely obese quickly or stay that way terribly long. That said, an average BMI for a Pork Elf is 35 for women, 25 for men, so they already would start off quiet fat. Although should a pork elf become excessively fat their body can handle it quiet well, but in addition they have evolved to not suffer from weight and diet related issues like diabetes, gout, hypertension no matter what weight.
