Is Obesity Genetic? What Science Has To Say
Science has so much to say when it comes to the question “Is obesity genetic?”
For starters, genes do play a significant role in human physiology, adaptation, development, and even other aspects of life.

The brain then coordinates these impulses with other inputs to be able to send instructions to the body. The result is either of two outcomes: consume more and spend less energy, or the opposite. Even the smallest alterations in these genes can influence their activity levels.
