Bodies are shaped by our environment, literally, bigger and smaller bodies are formed due to the environment.
What is it?
Bodies become smaller or larger depending on where they live and the circumstances in their environment. Shrinking due to the surrounding environment is called Insular Dwarfism while growing larger is called Insular Giantism. J. Bristol Foster observed this phenomenon in 1964. According to Tibi Puiu, bigger bodies have a larger food choice so larger animals will live in places there is a vast amount of food and prey. Smaller animals would require less food and are able to have shorter breeding cycles to keep up the species population in that environment. Some people and animals become smaller due to not having a lot of land to provide food source. Therefore a smaller animal or person would not need to eat as much because they would not burn as much energy as a larger person. Because the more you burn, the more you would need to eat, a smaller person would need to eat less.
How does it relate?
It relates because it shows that depending on where people and non-human animals are from, our bodies can differ in size. Foster's rule demonstrates that we are not all meant to be the same size as our ancestors lived in different environments and places which lead to the body we have now. this is due to our ancestors evolving to fit their surrounding environment.
Eating
Because smaller people would need to eat less, this proves that some people are smaller and some people are bigger due to the Island effect. Ancestors and where they came from shape who we are today and evolution shapes our minds and bodies to how it sees fit for our survival.
Instead of listening to restrictive eating gimmicks, listen to your body and mind.
