Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]
"Your genes can play a role in your body shape and how easily you gain weight. While you can't change your genetics, understanding the cause can help reduce frustration," says Best. 23.
Steatopygia, a genetic characteristic leading to increased accumulation of adipose tissue in the buttock region, is most notably (but not solely) found among the Khoisan of Southern Africa. It has also been observed among Pygmies of Central Africa and also the Andamanese people, such as the Onge tribe in the Andaman Islands. This genetic ...
Yes, weight is linked to chronic diseases like type 2 diabetes, heart disease, fatty liver, kidney disease and stroke, but it is hard to establish a cause-and-effect relationship between weight ...
Obesity is a condition in which a person's weight is higher than what is considered healthy for their height, and is the leading cause of preventable death worldwide. Obesity can result from several factors such as poor nutritional choices, overeating, genetics, culture, and metabolism. [ 1 ]
A “hungry gut” gene may indicate who responds best to weight loss drugs like Ozempic and Wegovy, new research finds. “Hungry gut” refers to the type of obesity phenotype that occurs when ...
The extreme endpoint of this distribution are the so-called 'monogenic' obesities where most of the impact on body weight can be tied to a mutation in a single gene that runs in a single family. The classic example of such a genetic effect is the presence of mutations in the leptin gene. [29]
About 40% of American adults are living with obesity — and for many, it can feel a bit like a roller-coaster as their weight fluctuates. Experts explain the science behind "yo-yo dieting."
