Why Do Fat People Have So Big Calves? Is the key to big calves getting fat?

Calves represent one of the most problematic muscle groups ever. There are many professional bodybuilders such as Dennis Wolf who are extremely large and yet their calves are weak and small compared to those of a typical fat lady. Question is, why do most fat people have such big calves without even working out?

Higher Bodyweight = More Work For The Calves

When you are overweight your whole body has to work way harder than usual. That’s true for your heart, stomach…and even calves.

Obviously, the calves of a fat person are doing more work during common activities such as walking, climbing stairs and running compared to the those of a featherweight which don’t have to lift nearly as heavy. As a result fat dudes get a solid workout from just walking their dogs.

Fat People = Endomorphs = Big Bones = Bigger Calves

Most truly fat people tend to have bigger bones. Bigger bones immediately equal more muscle mass. A person that has 6′ inch wrists will naturally have a smaller arm compared to someone with 8′ inch wrists. The same is true for the calves. When your ankles are big, your calves will be big naturally.

Short Insertions = Longer Muscle Bellies = Bigger Calves

Unlike ectmorphs most fat people have short tendons and longer muscle bellies. Of course, this is not always the case but it’s quite common. When you have short Achilles tendon and long calf bellies, you are one of those people that have naturally big calves no matter what. Somebody with super long Achilles tendons (sprinters) will usually have short muscle bellies and respectively smaller calf muscles.

When you’re fat your are obviously fed with sufficient calories to grow. This means that the conditions for muscular growth are met and the body has sufficient nutrients to cover the basics and then some. This is also one of the reasons why fat people tend to carry more muscle than your average skinny dude.

It’s not all muscle!

If right now you gain 20 lbs and 15 lbs of it is fat and the rest 5 lbs glycogen, you will still look more impressive than before, and people will think you’ve gained some serious mass, especially when you wear clothes. Fat creates the illusion that you have more muscle mass than what you really have. This is true even for the calves of fat people. Sure, a lot of it is actual muscle but once they diet down, the calves will downsize quite a bit. The good news is that your moobs and cankles will finally be gone too.

Not all fat people are built the same!

If a classical ectomorph – skinny wrists, lengthy bones, short muscle bellies, naturally skinny – decides to get mega fat, he/she won’t look the same as a ‘born to be fat person’. When ectomorphs get fat, most of it goes to the belly and the extremities remain skinny. The end result is the so called skinny fat look. Diets such as GOMAD have created hundreds of examples.
